## Getting Started
### Installation
```bash
npm install @astermind/astermind-pro @astermind/astermind-elm
```
### License Setup
Astermind Pro uses a **centralized license configuration** that automatically propagates to both Pro and Synth.
**Option 1: Configuration File (Recommended)**
Edit `src/config/license-config.ts`:
```typescript
export const LICENSE_TOKEN: string | null = 'YOUR_LICENSE_TOKEN_HERE';
```
**Option 2: Environment Variable**
```bash
export ASTERMIND_LICENSE_TOKEN="your-license-token-here"
```
**Option 3: Programmatic**
```typescript
import { initializeLicense, setLicenseTokenFromString } from '@astermind/astermind-pro';
initializeLicense();
await setLicenseTokenFromString('your-license-token-here');
```
The license automatically propagates to:
- ✅ Astermind Pro (primary)
- ✅ Astermind Synth (included with Pro subscription)
See [LICENSE_SETUP.md](../config/LICENSE_SETUP.md) for complete guide.
### Basic Import
```typescript
import {
// License Management
initializeLicense, checkLicense, setLicenseTokenFromString,
// Math utilities
cosine, l2, normalizeL2, ridgeSolvePro, OnlineRidge, buildRFF, mapRFF,

} from '@astermind/astermind-pro';
```
**Note:** Astermind Pro subscription includes **Astermind Synth** - a synthetic data generator for bootstrapping your projects. See the [Bootstrapping with Astermind Synth](#bootstrapping-with-astermind-synth) section below.
---
## Bootstrapping with Astermind Synth
**Astermind Synth is included with every Astermind Pro subscription** and provides synthetic data generation to bootstrap your ML projects quickly.
### Why Use Synth?
- **Start Immediately** - Generate training data in minutes, not days
- **Test Pipelines** - Validate your architecture before production data
- **Rare Scenarios** - Generate edge cases and rare examples
- **Privacy-Safe** - Use synthetic data for development and testing
- **Rapid Prototyping** - Iterate quickly on new ideas
### Installation
Synth is included with Pro, but you can also install it separately:
```bash
npm install @astermind/astermind-synthetic-data
```
### Quick Start
```typescript
import { loadPretrained } from '@astermind/astermind-synthetic-data';
// Load pretrained model (ready to use)
const synth = loadPretrained('retrieval');
// Generate synthetic data
const firstName = await synth.generate('first_name');
const email = await synth.generate('email');
const phone = await synth.generate('phone_number');
console.log(`${firstName} - ${email} - ${phone}`);
```
### Generation Modes
Synth offers 5 generation modes with different realism levels:
1. **`retrieval`** - Fully realistic formats from curated examples (100% format realism)
2. **`exact`** - High-fidelity retrieval with pattern variations (95-100% realism)
3. **`hybrid`** - Blends retrieval with ELM jitter (80-90% realism)
4. **`elm`** - ELM-based generation with label conditioning (75-85% realism)
5. **`premium`** - Best-of-all-worlds combining all improvements (85-100% realism)
### Pretrained Labels
The pretrained model supports these labels out of the box:
- **Names**: `first_name`, `last_name`
- **Contact**: `phone_number`, `email`
- **Address**: `street_address`, `city`, `state`, `country`
- **Business**: `company_name`, `job_title`, `product_name`
- **Other**: `color`, `uuid`, `date`, `credit_card_type`, `device_type`
### Custom Training
Train Synth on your own data:
```typescript
import { OmegaSynth } from '@astermind/astermind-synthetic-data';
const synth = new OmegaSynth({
mode: 'hybrid',
maxLength: 50,
usePatternCorrection: true
});
const customData = [
{ label: 'product_code', value: 'PROD-001' },
{ label: 'product_code', value: 'PROD-002' },
{ label: 'sku', value: 'SKU-ABC-123' },
{ label: 'sku', value: 'SKU-XYZ-456' }
];
await synth.train(customData);
// Generate from your custom labels
const productCode = await synth.generate('product_code');
const sku = await synth.generate('sku');
```
### Bootstrapping ELM Models
Use Synth to generate training data for ELM models:
```typescript
import { loadPretrained } from '@astermind/astermind-synthetic-data';
import { ELM } from '@astermind/astermind-elm';
// Step 1: Load Synth and generate training data
const synth = loadPretrained('hybrid');
await new Promise(resolve => setTimeout(resolve, 100)); // Wait for initialization
const labels = ['first_name', 'last_name', 'email', 'phone_number'];
const trainingData: Array<{ text: string; label: string }> = [];
for (const label of labels) {
const samples = await synth.generateBatch(label, 100);
for (const value of samples) {
trainingData.push({ text: value, label });
}
}
// Step 2: Train ELM on synthetic data
const texts = trainingData.map(d => d.text);
const labelArray = trainingData.map(d => d.label);
const uniqueLabels = Array.from(new Set(labelArray));
const elm = new ELM({
useTokenizer: true,
hiddenUnits: 256,
categories: uniqueLabels,
maxLen: 50
});
(elm as any).setCategories(uniqueLabels);
// Encode and train
const labelIndices = labelArray.map(l => uniqueLabels.indexOf(l));
const encodedTexts = texts.map(text => {
const encoded = (elm as any).encoder.encode(text);
return (elm as any).encoder.normalize(encoded);
});
elm.trainFromData(encodedTexts, labelIndices);
// Step 3: Test the model
const predictions = elm.predict('john.doe@example.com', 3);
console.log(predictions); // Should predict 'email' with high confidence
```
### Bootstrapping Complete Pipelines
Combine Synth, ELM, and Pro features for complete solutions:
```typescript
import { loadPretrained } from '@astermind/astermind-synthetic-data';
import { ELM } from '@astermind/astermind-elm';
import { rerankAndFilter, summarizeDeterministic } from '@astermind/astermind-pro';
// 1. Generate synthetic knowledge base
const synth = loadPretrained('retrieval');
const kbChunks = [];
for (let i = 0; i < 100; i++) {
const product = await synth.generate('product_name');
const company = await synth.generate('company_name');
const description = `Product ${product} by ${company}. High quality and reliable.`;
kbChunks.push({
heading: product,
content: description,
score_base: Math.random()
});
}
// 2. Train ELM classifier for intent detection
const intentData = [
{ text: 'What is the price?', label: 'pricing' },
{ text: 'How do I use this?', label: 'usage' },
{ text: 'What are the features?', label: 'features' }
];
const elm = new ELM({
useTokenizer: true,
hiddenUnits: 128,
categories: ['pricing', 'usage', 'features'],
maxLen: 50
});
// Train ELM (simplified - see full example above)
// ...
// 3. Use Pro features for RAG
async function answerQuery(query: string) {
// Detect intent
const intent = elm.predict(query, 1)[0].label;
// Retrieve and rerank
const reranked = rerankAndFilter(query, kbChunks, {
lambdaRidge: 1e-2,
probThresh: 0.45,
useMMR: true,
budgetChars: 1200
});
// Summarize
const summary = summarizeDeterministic(query, reranked, {
maxAnswerChars: 1000,
includeCitations: true
});
return {
intent,
answer: summary.text,
sources: summary.cites
};
}
```
### Fine-Tuning Pretrained Models
Add your own data to pretrained models:
```typescript
import { loadPretrained } from '@astermind/astermind-synthetic-data';
// Load pretrained
const synth = loadPretrained('retrieval');
await new Promise(resolve => setTimeout(resolve, 100));
// Add custom data
const customData = [
{ label: 'product_name', value: 'MyProduct A' },
{ label: 'product_name', value: 'MyProduct B' },
{ label: 'custom_field', value: 'Custom Value' }
];
await synth.train(customData);
// Now can generate from both pretrained and custom labels
const product = await synth.generate('product_name'); // Uses both pretrained + custom
const custom = await synth.generate('custom_field'); // Uses only custom
const email = await synth.generate('email'); // Uses only pretrained
```
### Batch Generation
Generate multiple samples at once:
```typescript
const synth = loadPretrained('hybrid');
// Generate 100 email addresses
const emails = await synth.generateBatch('email', 100);
// Generate diverse dataset
const dataset = [];
for (const label of ['first_name', 'last_name', 'email', 'phone_number']) {
const samples = await synth.generateBatch(label, 50);
for (const value of samples) {
dataset.push({ label, value });
}
}
```
### Advanced Configuration
```typescript
import { OmegaSynth } from '@astermind/astermind-synthetic-data';
const synth = new OmegaSynth({
mode: 'premium', // Best quality
maxLength: 50, // Max string length
seed: 42, // For reproducibility
usePatternCorrection: true, // Enable pattern correction
useOneHot: false, // Memory-efficient (set true if memory allows)
useClassification: false, // Use regression (set true for discrete outputs)
exactMode: false // For hybrid: use jitter (set true for 0% jitter)
});
await synth.train(customData);
const result = await synth.generate('label');
```
### Integration with Pro Features
Synth works seamlessly with Pro features:
```typescript
import { loadPretrained } from '@astermind/astermind-synthetic-data';
import { rerankAndFilter, InfoFlowGraph } from '@astermind/astermind-pro';
// Generate synthetic test queries
const synth = loadPretrained('retrieval');
const testQueries = await synth.generateBatch('product_name', 20);
// Test reranking system
const graph = new InfoFlowGraph({ window: 256 });
for (const query of testQueries) {
const results = rerankAndFilter(query, documents, {
lambdaRidge: 1e-2
});
// Monitor information flow
graph.get('Query->Results').push(
[query.length / 100],
[results.length]
);
}
const snapshot = graph.snapshot();
console.log('Information flow:', snapshot);
```

## Core Concepts
### 1. **Modular Architecture**
Every component is independent and composable:
- Use individual functions/classes as needed
- Mix and match components
- Build custom pipelines
### 2. **No Private APIs**
Everything is public and extensible:
- All functions are exported
- All types are accessible
- No hidden implementation details
### 3. **Pipeline Pattern**
Typical pipeline flow:
```
Input → Preprocessing → Retrieval → Reranking → Summarization → Output
```
You can customize any stage or skip stages entirely.

## API Reference
### Math Utilities
#### Vector Operations
```typescript
import { dot, add, scal, normalizeL2, l2, cosine } from '@astermind/astermind-pro';
// Create vectors
const a = new Float64Array([1, 2, 3]);
const b = new Float64Array([4, 5, 6]);
// Dot product
const dotProduct = dot(a, b); // 32
// Vector addition
const sum = add(a, b); // [5, 7, 9]
// Scalar multiplication
const scaled = scal(a, 2); // [2, 4, 6]
// L2 norm
const norm = l2(a); // ~3.74
// Normalize
const normalized = normalizeL2(a); // Unit vector
// Cosine similarity
const similarity = cosine(a, b); // 0.9746
```
#### Advanced Math
```typescript
import { softmax, sigmoid, expSafe, logSumExp } from '@astermind/astermind-pro';
// Softmax (stable implementation)
const logits = new Float64Array([2.0, 1.0, 0.1]);
const probs = softmax(logits); // [0.659, 0.242, 0.099]
// Sigmoid (overflow-safe)
const x = 10;
const prob = sigmoid(x); // ~0.9999
// Safe exponential
const large = expSafe(700); // Won't overflow
```
### Kernel Ridge Regression (KRR)
```typescript
import { ridgeSolvePro, RidgeOptions } from '@astermind/astermind-pro';
// Solve (K + λI)Θ = Y
const K = [
[1.0, 0.5, 0.3],
[0.5, 1.0, 0.4],
[0.3, 0.4, 1.0]
];
const Y = [[1.0], [0.8], [0.6]];
const options: RidgeOptions = {
lambda: 0.01,
ensureSymmetry: true,
cgTol: 1e-6,
cgMaxIter: 1000
};
const result = ridgeSolvePro(K, Y, options);
console.log(result.Theta); // Solution matrix
console.log(result.method); // "cholesky" or "cg"
console.log(result.info); // Diagnostics
```
### Online Ridge Regression
```typescript
import { OnlineRidge } from '@astermind/astermind-pro';
// Initialize: p features, m outputs, lambda regularization
const ridge = new OnlineRidge(64, 1, 1e-3);
// Update incrementally (rank-1 updates)
for (const [features, target] of trainingData) {
const phi = new Float64Array(features);
const y = new Float64Array([target]);
ridge.update(phi, y);
}
// Predict
const newFeatures = new Float64Array([...]);
const prediction = ridge.predict(newFeatures);
```
### Random Fourier Features (RFF)
```typescript
import { buildRFF, mapRFF } from '@astermind/astermind-pro';
// Build RFF for RBF kernel approximation
const rff = buildRFF(
d: 128, // input dimension
D: 32, // features per cos/sin block (output is 2D = 64)
sigma: 1.0, // kernel bandwidth
rng: Math.random
);
// Map input to RFF space
const input = new Float64Array(128); // your input vector
const rffFeatures = mapRFF(rff, input); // 64-dimensional output
```
### Omega RAG System
```typescript
import { omegaComposeAnswer, RetrievedChunk, OmegaOptions } from '@astermind/astermind-pro';
const chunks: RetrievedChunk[] = [
{ heading: "Chapter 1", content: "..." },
{ heading: "Chapter 2", content: "..." }
];
const options: OmegaOptions = {
dim: 64,
features: 32,
sigma: 1.0,
rounds: 3,
topSentences: 8,
personality: "teacher" // "neutral" | "teacher" | "scientist"
};
const answer = await omegaComposeAnswer(
"How does X work?",
chunks,
options
);
```
### Reranking (OmegaRR)
```typescript
import { rerank, rerankAndFilter, filterMMR, Chunk, RerankOptions } from '@astermind/astermind-pro';
const chunks: Chunk[] = [
{ heading: "Doc 1", content: "...", score_base: 0.8 },
{ heading: "Doc 2", content: "...", score_base: 0.7 }
];
const options: RerankOptions = {
lambdaRidge: 1e-2,
useMMR: true,
mmrLambda: 0.7,
probThresh: 0.45,
epsilonTop: 0.05,
budgetChars: 1200,
randomProjDim: 32,
exposeFeatures: true, // Get feature vectors
attachFeatureNames: true // Get feature names
};
// Rerank only
const scored = rerank("query", chunks, options);
// Rerank + filter in one call
const filtered = rerankAndFilter("query", chunks, options);
// Access engineered features
scored.forEach(chunk => {
console.log(chunk.score_rr); // Reranker score
console.log(chunk.p_relevant); // Relevance probability
console.log(chunk._features); // Feature vector (if exposeFeatures=true)
console.log(chunk._feature_names); // Feature names (if attachFeatureNames=true)
});
```
### Summarization (OmegaSumDet)
```typescript
import { summarizeDeterministic, ScoredChunk, SumOptions } from '@astermind/astermind-pro';
const chunks: ScoredChunk[] = [
{
heading: "Section 1",
content: "...",
rrScore: 0.9,
rrRank: 0
}
];
const options: SumOptions = {
maxAnswerChars: 900,
maxBullets: 6,
preferCode: true,
includeCitations: true,
teWeight: 0.25,
queryWeight: 0.45,
evidenceWeight: 0.20,
rrWeight: 0.10,
codeBonus: 0.05,
headingBonus: 0.04,
jaccardDedupThreshold: 0.6,
allowOffTopic: false,
minQuerySimForCode: 0.40,
maxSectionsInAnswer: 1
};
const result = summarizeDeterministic("query", chunks, options);
console.log(result.text); // Generated summary
console.log(result.cites); // Citations
```
### Transfer Entropy
```typescript
import { TransferEntropy, InfoFlowGraph, InfoFlowGraphPWS } from '@astermind/astermind-pro';
// Basic Transfer Entropy
const te = new TransferEntropy({
window: 256,
condLags: 1,
xLags: 1,
ridge: 1e-3,
bits: true
});
// Push synchronized samples
te.push([0.5, 0.3], [0.7, 0.2]); // X, Y as vectors or scalars
// Estimate TE(X→Y)
const teValue = te.estimate(); // in bits
// InfoFlow Graph (multiple channels)
const graph = new InfoFlowGraph({
window: 256,
condLags: 1,
xLags: 1,
ridge: 1e-6,
bits: true
});
// Monitor multiple information flows
graph.get('Query->Score').push(queryVec, scoreVec);
graph.get('Feature->Relevance').push(featureVec, relevanceVec);
// Get snapshot
const snapshot = graph.snapshot();
// { 'Query->Score': 0.0234, 'Feature->Relevance': 0.0156 }
// PWS variant (Phase-Weighted Stacking)
const graphPWS = new InfoFlowGraphPWS({
window: 256,
usePWS: true,
tailQuantile: 0.9,
tailBoost: 4,
jitterSigma: 0.15,
pwsIters: 8
});
```
### TE Controller (Closed-Loop Control)
```typescript
import { TEController, Knobs } from '@astermind/astermind-pro';
const controller = new TEController({
targets: {
q2score: [0.01, 0.10], // Query→Score TE band
feat2score: [0.01, 0.10], // Feature→Score TE band
kept2sum: [0.01, 0.10], // Kept→Summary TE band
loopMax: 0.25 // Max loop TE
},
limits: {
alpha: [0.4, 0.98],
sigma: [0.12, 1.0],
ridge: [0.01, 0.2],
probThresh: [0.3, 0.7],
mmrLambda: [0.4, 0.9],
budgetChars: [600, 2400]
},
step: {
alpha: 0.03,
sigma: 0.04,
ridge: 0.01,
probThresh: 0.03,
mmrLambda: 0.05,
budgetChars: 120
},
cooldown: 2,
maxPerSessionAdjusts: 24,
trustMinSamples: 8
});
// Update with TE snapshot
controller.pushTE({
'Retriever:Q->Score': 0.05,
'OmegaRR:Feat->Score': 0.08,
'Omega:Kept->Summary': 0.12
});
// Get adaptive adjustments
const current: Knobs = {
alpha: 0.7,
sigma: 0.35,
ridge: 0.05,
probThresh: 0.45,
mmrLambda: 0.7,
budgetChars: 1200
};
const adjustment = controller.maybeAdjust(current);
if (adjustment.knobs) {
// Use adjusted knobs
console.log(adjustment.note); // Explanation of change
}
```
---
## Building Custom Pipelines
### Example 1: Simple Retrieval Pipeline
```typescript
import { cosine, normalizeL2 } from '@astermind/astermind-pro';
// Custom sparse retrieval
function customRetrieval(
query: string,
documents: Array<{ id: string; content: string; embedding: Float64Array }>
): Array<{ id: string; score: number }> {
// Tokenize and embed query (using your own embedding method)
const queryEmbedding = embedQuery(query);
const normalizedQuery = normalizeL2(queryEmbedding);
// Score all documents
const scored = documents.map(doc => {
const normalizedDoc = normalizeL2(doc.embedding);
const score = cosine(normalizedQuery, normalizedDoc);
return { id: doc.id, score };
});
// Sort by score
return scored.sort((a, b) => b.score - a.score);
}
```
### Example 2: Multi-Stage Reranking Pipeline
```typescript
import { rerank, filterMMR, rerankAndFilter } from '@astermind/astermind-pro';
// Custom multi-stage pipeline
async function multiStageReranking(
query: string,
initialResults: Chunk[],
stages: Array<{ name: string; options: RerankOptions }>
) {
let current = initialResults;
// Apply reranking stages sequentially
for (const stage of stages) {
console.log(`Applying ${stage.name}...`);
// Rerank with stage-specific options
const reranked = rerank(query, current, stage.options);
// Optional: Apply custom filtering between stages
if (stage.name === 'coarse') {
// Keep top 50% after coarse stage
current = reranked.slice(0, Math.ceil(reranked.length / 2));
} else {
current = reranked;
}
}
// Final MMR filtering
const final = filterMMR(current, {
useMMR: true,
mmrLambda: 0.7,
budgetChars: 2000
});
return final;
}
// Usage
const results = await multiStageReranking("query", chunks, [
{ name: 'coarse', options: { lambdaRidge: 1e-1, randomProjDim: 16 } },
{ name: 'fine', options: { lambdaRidge: 1e-2, randomProjDim: 32 } },
{ name: 'precise', options: { lambdaRidge: 1e-3, randomProjDim: 64 } }
]);
```
### Example 3: Custom Summarization with Intent Detection
```typescript
import { summarizeDeterministic } from '@astermind/astermind-pro';
// Custom intent-aware summarization
function intentAwareSummary(
query: string,
chunks: ScoredChunk[],
intent: 'code' | 'explanation' | 'reference'
) {
const baseOptions: SumOptions = {
maxAnswerChars: 1000,
includeCitations: true,
preferCode: intent === 'code'
};
// Adjust options based on intent
const options: SumOptions = {
...baseOptions,
...(intent === 'code' && {
codeBonus: 0.15, // Higher code bonus
minQuerySimForCode: 0.30, // Lower threshold
maxSectionsInAnswer: 2 // Allow more sections for code
}),
...(intent === 'explanation' && {
queryWeight: 0.60, // Higher query weight
maxBullets: 8 // More bullets for explanations
}),
...(intent === 'reference' && {
evidenceWeight: 0.30, // Higher evidence weight
includeCitations: true // Always include citations
})
};
return summarizeDeterministic(query, chunks, options);
}
// Detect intent from query
function detectIntent(query: string): 'code' | 'explanation' | 'reference' {
if (/\b(how|why|what|explain|describe)\b/i.test(query)) {
return 'explanation';
}
if (/\b(code|function|class|method|example|snippet)\b/i.test(query)) {
return 'code';
}
return 'reference';
}
// Usage
const intent = detectIntent("How do I implement authentication?");
const summary = intentAwareSummary(query, chunks, intent);
```
### Example 4: Information Flow Monitoring Pipeline
```typescript
import { InfoFlowGraph, TEController } from '@astermind/astermind-pro';
// Monitor information flow in your pipeline
class MonitoredPipeline {
private graph: InfoFlowGraph;
private controller: TEController;
constructor() {
this.graph = new InfoFlowGraph({
window: 256,
condLags: 1,
xLags: 1,
bits: true
});
this.controller = new TEController({
targets: {
q2score: [0.01, 0.10],
feat2score: [0.01, 0.10],
kept2sum: [0.01, 0.10]
}
});
}
async process(query: string, documents: Chunk[]) {
// Stage 1: Retrieval
const retrieved = this.retrieve(query, documents);
const querySig = this.getSignature(query);
const retrievalSig = this.getSignature(retrieved);
this.graph.get('Query->Retrieval').push(querySig, retrievalSig);
// Stage 2: Reranking
const reranked = rerank(query, retrieved, { exposeFeatures: true });
reranked.forEach(chunk => {
if (chunk._features) {
this.graph.get('Feature->Score').push(
chunk._features,
[chunk.score_rr]
);
}
});
// Stage 3: Summarization
const summary = summarizeDeterministic(query, reranked);
const summarySig = this.getSignature(summary.text);
const keptSig = this.getSignature(reranked.map(c => c.content).join(' '));
this.graph.get('Kept->Summary').push(keptSig, summarySig);
// Check TE and adjust if needed
const teSnapshot = this.graph.snapshot();
this.controller.pushTE(teSnapshot);
const adjustment = this.controller.maybeAdjust(this.getCurrentKnobs());
if (adjustment.knobs) {
console.log(`Auto-adjusted: ${adjustment.note}`);
// Apply adjusted knobs in next iteration
}
return { summary, teSnapshot, adjustment };
}
private getSignature(text: string): number[] {
// Convert text to signature vector (simplified)
return [text.length / 1000, text.split(' ').length / 100];
}
private getCurrentKnobs() {
return {
alpha: 0.7,
sigma: 0.35,
ridge: 0.05,
probThresh: 0.45,
mmrLambda: 0.7,
budgetChars: 1200
};
}
}
```
### Example 5: Hybrid Retrieval with Custom Kernels
```typescript
import { buildRFF, mapRFF, cosine, ridgeSolvePro } from '@astermind/astermind-pro';
// Custom hybrid retrieval combining multiple signals
class HybridRetriever {
private rff: ReturnType<typeof buildRFF>;
private sparseWeights: Map<string, number>;
constructor() {
this.rff = buildRFF(128, 32, 1.0);
this.sparseWeights = new Map();
}
retrieve(
query: string,

### Pattern 2: Multi-Modal Retrieval
```typescript

class MultiModalRetriever {
async retrieve(
query: { text: string; image?: Float64Array; audio?: Float64Array },

}>
) {
// Text retrieval

## Advanced Architectures: Ensembles & Chaining
Advanced ML architectures using ensemble methods and model chaining for improved performance and complex problem solving.
### Overview
**Ensemble Methods**: Combine multiple models to improve accuracy and robustness
- **ELM/ELM Ensemble**: Multiple ELM models voting together
- **KELM/ELM Ensemble**: KernelELM and ELM combined for non-linear + linear patterns
**Chaining Methods**: Feed one model's output into another for hierarchical processing
- **ELM Chaining**: Sequential ELM models (feature extraction → classification)
- **KELM/ELM Chaining**: KernelELM for feature extraction, ELM for final classification
- **ELM/KELM Chaining**: ELM for initial processing, KernelELM for refinement
---
### Ensemble Method 1: ELM/ELM Ensemble
**Use Case**: When you need robust classification with multiple perspectives
```typescript
import { ELM } from '@astermind/astermind-elm';
class ELMEnsemble {
private models: ELM[] = [];
private categories: string[];
constructor(categories: string[], numModels: number = 3) {
this.categories = categories;
// Create multiple ELM models with different configurations
for (let i = 0; i < numModels; i++) {
const elm = new ELM({
useTokenizer: true,
hiddenUnits: 256 + i * 64, // Vary hidden units
categories,
maxLen: 100,
activation: i % 2 === 0 ? 'relu' : 'tanh' // Vary activation
});
this.models.push(elm);
}
}
async train(trainingData: Array<{ text: string; label: string }>) {
const texts = trainingData.map(d => d.text);
const labels = trainingData.map(d => d.label);
const labelIndices = labels.map(l => this.categories.indexOf(l));
// Train each model independently
for (const elm of this.models) {
(elm as any).setCategories(this.categories);
const encodedTexts = texts.map(text => {
const encoded = (elm as any).encoder.encode(text);
return (elm as any).encoder.normalize(encoded);
});
elm.trainFromData(encodedTexts, labelIndices);
}
}
predict(text: string, topK: number = 3): Array<{ label: string; prob: number }> {
// Get predictions from all models
const allPredictions = this.models.map(elm => elm.predict(text, topK));
// Combine predictions (weighted voting)
const combined = new Map<string, number>();
allPredictions.forEach((predictions, modelIdx) => {
const weight = 1.0 / this.models.length; // Equal weight
predictions.forEach(p => {
const current = combined.get(p.label) || 0;
combined.set(p.label, current + p.prob * weight);
});
});
// Convert to array and sort
const result = Array.from(combined.entries())
.map(([label, prob]) => ({ label, prob }))
.sort((a, b) => b.prob - a.prob)
.slice(0, topK);
return result;
}
// Confidence-based weighting (higher confidence models get more weight)
predictWeighted(text: string, topK: number = 3): Array<{ label: string; prob: number }> {
const allPredictions = this.models.map(elm => {
const preds = elm.predict(text, 1);
return {
predictions: elm.predict(text, topK),
confidence: preds[0]?.prob || 0
};
});
// Weight by confidence
const totalConfidence = allPredictions.reduce((sum, p) => sum + p.confidence, 0);
const combined = new Map<string, number>();
allPredictions.forEach(({ predictions, confidence }) => {
const weight = totalConfidence > 0 ? confidence / totalConfidence : 1 / this.models.length;
predictions.forEach(p => {
const current = combined.get(p.label) || 0;
combined.set(p.label, current + p.prob * weight);
});
});
return Array.from(combined.entries())
.map(([label, prob]) => ({ label, prob }))
.sort((a, b) => b.prob - a.prob)
.slice(0, topK);
}
}
```
**Business Use Case**: Customer support ticket classification
- Multiple ELM models trained on different data splits
- Ensemble voting reduces misclassification
- Confidence weighting prioritizes reliable models
---
### Ensemble Method 2: KELM/ELM Ensemble
**Use Case**: Combining linear (ELM) and non-linear (KernelELM) pattern recognition
```typescript
import { ELM, KernelELM } from '@astermind/astermind-elm';
class KELMELMEnsemble {
private elm: ELM;
private kelm: KernelELM;

categories,
maxLen: 100
});
// KernelELM for non-linear patterns
this.kelm = new KernelELM({
outputDim: categories.length,
kernel: {
type: 'rbf',
gamma: 0.01
},
ridgeLambda: 0.001,
task: 'classification',
mode: 'nystrom',
nystrom: {
m: 100,
strategy: 'uniform'
}
});
}
async train(trainingData: Array<{ text: string; label: string }>) {
const texts = trainingData.map(d => d.text);
const labels = trainingData.map(d => d.label);
// Train ELM
(this.elm as any).setCategories(this.categories);
const labelIndices = labels.map(l => this.categories.indexOf(l));
const encodedTexts = texts.map(text => {
const encoded = (this.elm as any).encoder.encode(text);
return (this.elm as any).encoder.normalize(encoded);
});
this.elm.trainFromData(encodedTexts, labelIndices);
this.encoder = (this.elm as any).encoder;
// Train KernelELM on same encoded features
const oneHotLabels = labels.map(label => {
const idx = this.categories.indexOf(label);
const oneHot = new Array(this.categories.length).fill(0);
oneHot[idx] = 1;
return oneHot;
});
this.kelm.fit(encodedTexts, oneHotLabels);
}
predict(text: string, topK: number = 3, kelmWeight: number = 0.6): Array<{ label: string; prob: number }> {
// ELM prediction
const elmPreds = this.elm.predict(text, this.categories.length);
const elmProbs = new Array(this.categories.length).fill(0);
elmPreds.forEach(p => {
const idx = this.categories.indexOf(p.label);
if (idx >= 0) elmProbs[idx] = p.prob;
});
// KernelELM prediction
const encoded = this.encoder.encode(text);
const normalized = this.encoder.normalize(encoded);
const kelmProbs = this.kelm.predictProbaFromVectors([normalized])[0];
// Combine (weighted average)
const elmWeight = 1 - kelmWeight;
const combined = this.categories.map((label, idx) => ({
label,
prob: elmWeight * elmProbs[idx] + kelmWeight * kelmProbs[idx]
}));
return combined
.sort((a, b) => b.prob - a.prob)
.slice(0, topK);
}
}
```
**Business Use Case**: Fraud detection
- ELM captures linear patterns (amount thresholds, time patterns)
- KernelELM captures complex non-linear interactions
- Ensemble improves detection accuracy
---
### Chaining Method 1: ELM Chaining (Feature Extraction → Classification)
**Use Case**: Hierarchical feature learning and classification
```typescript
import { ELM } from '@astermind/astermind-elm';
class ELMChain {
private featureExtractor: ELM;
private classifier: ELM;
private categories: string[];
constructor(categories: string[]) {
this.categories = categories;
// First ELM: Feature extraction (autoencoder-like)
this.featureExtractor = new ELM({
useTokenizer: true,
hiddenUnits: 512, // Large hidden layer for rich features
categories: [], // No classification, just feature extraction
maxLen: 200,
activation: 'relu'
});
// Second ELM: Classification on extracted features
this.classifier = new ELM({
useTokenizer: false, // Input is already feature vectors
inputSize: 512, // Matches feature extractor output
categories,
hiddenUnits: 256,
activation: 'tanh'
});
}
async train(trainingData: Array<{ text: string; label: string }>) {
const texts = trainingData.map(d => d.text);
const labels = trainingData.map(d => d.label);
// Step 1: Train feature extractor (reconstruct input)
(this.featureExtractor as any).setCategories([]);
const encodedTexts = texts.map(text => {
const encoded = (this.featureExtractor as any).encoder.encode(text);
return (this.featureExtractor as any).encoder.normalize(encoded);
});
// Train as autoencoder (input -> input)
this.featureExtractor.trainFromData(encodedTexts, encodedTexts);
// Step 2: Extract features using trained extractor
const extractedFeatures = encodedTexts.map(encoded => {
// Get hidden layer representation
const hidden = (this.featureExtractor as any).buildHidden(
[encoded],
(this.featureExtractor as any).model.W,
(this.featureExtractor as any).model.b
);
return hidden[0];
});
// Step 3: Train classifier on extracted features
const labelIndices = labels.map(l => this.categories.indexOf(l));
this.classifier.trainFromData(extractedFeatures, labelIndices);
}
predict(text: string, topK: number = 3): Array<{ label: string; prob: number }> {
// Step 1: Extract features
const encoded = (this.featureExtractor as any).encoder.encode(text);
const normalized = (this.featureExtractor as any).encoder.normalize(encoded);
const hidden = (this.featureExtractor as any).buildHidden(
[normalized],
(this.featureExtractor as any).model.W,
(this.featureExtractor as any).model.b
);
const features = hidden[0];
// Step 2: Classify
return this.classifier.predictFromVector([features], topK);
}
}
```
**Business Use Case**: Document categorization
- First ELM learns document-level features
- Second ELM classifies based on learned features
- Better generalization than single-stage classification
---
### Chaining Method 2: KELM/ELM Chaining (Non-linear Features → Linear Classification)
**Use Case**: Complex feature extraction with efficient classification
```typescript
import { ELM, KernelELM } from '@astermind/astermind-elm';

this.categories = categories;
// Temporary ELM for encoding
const tempELM = new ELM({
useTokenizer: true,
hiddenUnits: 256,
categories: [],
maxLen: 200
});
this.encoder = (tempELM as any).encoder;
// KernelELM for non-linear feature extraction
this.featureExtractor = new KernelELM({
outputDim: featureDim,
kernel: {
type: 'rbf',
gamma: 0.01
},
ridgeLambda: 0.001,
task: 'regression', // Feature extraction, not classification

nystrom: {
m: 100,
strategy: 'uniform'
}
});
// ELM for final classification
this.classifier = new ELM({
useTokenizer: false,
inputSize: featureDim,
categories,
hiddenUnits: 128,
activation: 'relu'
});
}
async train(trainingData: Array<{ text: string; label: string }>) {
const texts = trainingData.map(d => d.text);
const labels = trainingData.map(d => d.label);
// Encode texts
const encodedTexts = texts.map(text => {
const encoded = this.encoder.encode(text);
return this.encoder.normalize(encoded);
});
// Step 1: Train KernelELM feature extractor
// Use encoded texts as both input and target (autoencoder-like)
this.featureExtractor.fit(encodedTexts, encodedTexts);
// Step 2: Extract features using KernelELM
const extractedFeatures = this.featureExtractor.transform(encodedTexts);
// Step 3: Train ELM classifier on extracted features
const labelIndices = labels.map(l => this.categories.indexOf(l));
this.classifier.trainFromData(extractedFeatures, labelIndices);
}
predict(text: string, topK: number = 3): Array<{ label: string; prob: number }> {
// Step 1: Encode
const encoded = this.encoder.encode(text);
const normalized = this.encoder.normalize(encoded);
// Step 2: Extract features with KernelELM
const features = this.featureExtractor.transform([normalized])[0];
// Step 3: Classify with ELM
return this.classifier.predictFromVector([features], topK);
}
}
```
**Business Use Case**: Sentiment analysis
- KernelELM captures complex sentiment patterns
- ELM efficiently classifies on extracted features
- Better accuracy than single-stage models

### Chaining Method 3: ELM/KELM Chaining (Initial Processing → Refinement)
**Use Case**: Initial classification with non-linear refinement
```typescript
import { ELM, KernelELM } from '@astermind/astermind-elm';
class ELMKELMChain {
private initialClassifier: ELM;
private refiner: KernelELM;
private categories: string[];
constructor(categories: string[]) {
this.categories = categories;
// ELM for initial classification
this.initialClassifier = new ELM({
useTokenizer: true,
hiddenUnits: 256,
categories,
maxLen: 200
});
// KernelELM for refinement
this.refiner = new KernelELM({
outputDim: categories.length,
kernel: {
type: 'rbf',
gamma: 0.01
},
ridgeLambda: 0.001,
task: 'classification',
mode: 'nystrom',
nystrom: {
m: 50,
strategy: 'uniform'
}
});
}
async train(trainingData: Array<{ text: string; label: string }>) {
const texts = trainingData.map(d => d.text);
const labels = trainingData.map(d => d.label);
// Step 1: Train initial ELM classifier
(this.initialClassifier as any).setCategories(this.categories);
const labelIndices = labels.map(l => this.categories.indexOf(l));
const encodedTexts = texts.map(text => {
const encoded = (this.initialClassifier as any).encoder.encode(text);
return (this.initialClassifier as any).encoder.normalize(encoded);
});
this.initialClassifier.trainFromData(encodedTexts, labelIndices);
// Step 2: Get initial predictions as features
const initialFeatures = encodedTexts.map(encoded => {
const preds = this.initialClassifier.predictFromVector([encoded], this.categories.length)[0];
return preds.map(p => p.prob);
});
// Step 3: Train KernelELM refiner on initial predictions + original features
const combinedFeatures = encodedTexts.map((encoded, i) => {
return [...encoded, ...initialFeatures[i]];
});
const oneHotLabels = labels.map(label => {
const idx = this.categories.indexOf(label);
const oneHot = new Array(this.categories.length).fill(0);
oneHot[idx] = 1;
return oneHot;
});
this.refiner.fit(combinedFeatures, oneHotLabels);
}
predict(text: string, topK: number = 3): Array<{ label: string; prob: number }> {
// Step 1: Initial classification
const encoded = (this.initialClassifier as any).encoder.encode(text);
const normalized = (this.initialClassifier as any).encoder.normalize(encoded);
const initialPreds = this.initialClassifier.predictFromVector([normalized], this.categories.length)[0];
const initialProbs = initialPreds.map(p => p.prob);
// Step 2: Refine with KernelELM
const combined = [...normalized, ...initialProbs];
const refinedProbs = this.refiner.predictProbaFromVectors([combined])[0];
// Combine initial and refined (weighted)
const final = this.categories.map((label, idx) => ({
label,
prob: 0.3 * initialProbs[idx] + 0.7 * refinedProbs[idx]
}));
return final
.sort((a, b) => b.prob - a.prob)
.slice(0, topK);
}
}
```
**Business Use Case**: Medical diagnosis
- ELM provides initial diagnosis
- KernelELM refines based on initial prediction + symptoms
- Improved accuracy for complex cases

### Real-World Business Use Cases
#### Use Case 1: Multi-Stage Content Moderation
**Problem**: Classify content safety, then determine severity level
**Solution**: ELM Chain
```typescript
class ContentModerationSystem {
private safetyClassifier: ELM;
private severityClassifier: ELM;
async initialize() {
// Stage 1: Safety classification
this.safetyClassifier = new ELM({
useTokenizer: true,
hiddenUnits: 256,
categories: ['safe', 'unsafe'],
maxLen: 500
});
// Stage 2: Severity classification (only for unsafe content)
this.severityClassifier = new ELM({
useTokenizer: false,
inputSize: 256, // Features from safety classifier
categories: ['low', 'medium', 'high', 'critical'],
hiddenUnits: 128
});
}
async moderate(content: string) {
// Stage 1: Safety check
const safety = this.safetyClassifier.predict(content, 1)[0];
if (safety.label === 'safe') {
return { action: 'approve', safety: 'safe' };
}
// Stage 2: Extract features and classify severity
const encoded = (this.safetyClassifier as any).encoder.encode(content);
const normalized = (this.safetyClassifier as any).encoder.normalize(encoded);
const features = this.extractFeatures(normalized);
const severity = this.severityClassifier.predictFromVector([features], 1)[0];
return {
action: 'flag',
safety: 'unsafe',
severity: severity.label,
confidence: severity.prob
};
}
private extractFeatures(encoded: number[]): number[] {
// Extract hidden layer features from safety classifier
const hidden = (this.safetyClassifier as any).buildHidden(
[encoded],
(this.safetyClassifier as any).model.W,
(this.safetyClassifier as any).model.b
);
return hidden[0];
}
}
```
#### Use Case 2: Financial Risk Assessment
**Problem**: Assess credit risk with multiple factors
**Solution**: KELM/ELM Ensemble
```typescript
class CreditRiskAssessor {
private ensemble: KELMELMEnsemble;
async initialize() {
this.ensemble = new KELMELMEnsemble([
'low_risk',
'medium_risk',
'high_risk',
'reject'
]);
}
async assess(application: {
income: number;
creditScore: number;
debtRatio: number;
employmentHistory: string;
loanAmount: number;
}) {
// Format as text for processing
const text = `
Income: ${application.income}
Credit Score: ${application.creditScore}
Debt Ratio: ${application.debtRatio}
Employment: ${application.employmentHistory}
Loan Amount: ${application.loanAmount}
`;
// Ensemble prediction (KELM captures non-linear interactions)
const prediction = this.ensemble.predict(text, 1, 0.7); // 70% weight to KELM
return {
risk: prediction[0].label,
confidence: prediction[0].prob,
recommendation: this.getRecommendation(prediction[0].label)
};
}
private getRecommendation(risk: string): string {
const recommendations = {
low_risk: 'Approve with standard terms',
medium_risk: 'Approve with higher interest rate',
high_risk: 'Approve with strict terms',
reject: 'Reject application'
};
return recommendations[risk] || 'Review required';
}
}
```
#### Use Case 3: Hierarchical Document Classification
**Problem**: Classify documents by category, then by subcategory
**Solution**: ELM Chain
```typescript
class HierarchicalDocumentClassifier {
private categoryClassifier: ELM;
private subcategoryClassifiers: Map<string, ELM>;
async initialize() {
// Top-level categories
const categories = ['legal', 'financial', 'technical', 'medical'];
this.categoryClassifier = new ELM({
useTokenizer: true,
hiddenUnits: 512,
categories,
maxLen: 2000
});
// Subcategory classifiers (one per category)
this.subcategoryClassifiers = new Map();
const subcategories = {
legal: ['contract', 'brief', 'motion', 'opinion'],
financial: ['invoice', 'statement', 'report', 'analysis'],
technical: ['spec', 'manual', 'ticket', 'bug_report'],
medical: ['record', 'diagnosis', 'prescription', 'report']
};
for (const [category, subs] of Object.entries(subcategories)) {
const subClassifier = new ELM({
useTokenizer: false,
inputSize: 512, // Features from category classifier
categories: subs,
hiddenUnits: 256
});
this.subcategoryClassifiers.set(category, subClassifier);
}
}
async classify(document: string) {
// Stage 1: Category classification
const categoryPred = this.categoryClassifier.predict(document, 1)[0];
const category = categoryPred.label;
// Stage 2: Extract features
const encoded = (this.categoryClassifier as any).encoder.encode(document);
const normalized = (this.categoryClassifier as any).encoder.normalize(encoded);
const features = this.extractFeatures(normalized);
// Stage 3: Subcategory classification
const subClassifier = this.subcategoryClassifiers.get(category);
if (!subClassifier) {
return { category, subcategory: 'unknown' };
}
const subcategoryPred = subClassifier.predictFromVector([features], 1)[0];
return {
category,
categoryConfidence: categoryPred.prob,
subcategory: subcategoryPred.label,
subcategoryConfidence: subcategoryPred.prob
};

### Advanced Business Use Case: Intelligent Document Processing Pipeline
**Problem**: Process legal documents with multi-stage analysis: extract entities, classify document type, assess relevance, and generate summaries.
**Solution**: Combined chaining and ensemble methods
```typescript
import { ELM, KernelELM } from '@astermind/astermind-elm';
import { rerankAndFilter, summarizeDeterministic } from '@astermind/astermind-pro';
import { loadPretrained } from '@astermind/astermind-synthetic-data';
class IntelligentDocumentProcessor {
// Stage 1: Entity extraction (ELM)
private entityExtractor: ELM;
// Stage 2: Document type classification (KELM/ELM Ensemble)
private typeEnsemble: KELMELMEnsemble;
// Stage 3: Relevance assessment (ELM Chain)
private relevanceChain: ELMChain;
// Stage 4: Summary generation (Pro)
private synth: any;
constructor() {
// Entity extraction
const entityTypes = ['person', 'organization', 'date', 'amount', 'location'];
this.entityExtractor = new ELM({
useTokenizer: true,
hiddenUnits: 256,
categories: entityTypes,
maxLen: 500
});
// Document type classification (ensemble)
const docTypes = ['contract', 'brief', 'motion', 'opinion', 'correspondence'];
this.typeEnsemble = new KELMELMEnsemble(docTypes);
// Relevance assessment (chain)
const relevanceLevels = ['critical', 'important', 'relevant', 'low_priority'];
this.relevanceChain = new ELMChain(relevanceLevels);
// Synthetic data for testing
this.synth = loadPretrained('retrieval');
}
async processDocument(document: {
content: string;
metadata: any;
}) {
// Stage 1: Extract entities
const entities = await this.extractEntities(document.content);
// Stage 2: Classify document type (ensemble)
const docType = this.typeEnsemble.predict(document.content, 1, 0.6)[0];
// Stage 3: Assess relevance (chain)
const relevance = this.relevanceChain.predict(document.content, 1)[0];
// Stage 4: Generate summary if relevant
let summary = null;
if (relevance.label !== 'low_priority') {
const chunks = this.chunkDocument(document.content);
const reranked = rerankAndFilter(
`Summarize ${docType.label} document`,
chunks,
{
lambdaRidge: 1e-2,
probThresh: 0.5,
useMMR: true,
budgetChars: 2000
}
);
summary = summarizeDeterministic(
`Summarize ${docType.label} document`,
reranked,
{
personality: 'neutral',
maxAnswerChars: 1000,
includeCitations: true
}
);
}
// Stage 5: Generate synthetic test cases
const testCases = await this.generateTestCases(docType.label, 10);
return {
entities,
documentType: {
type: docType.label,
confidence: docType.prob
},
relevance: {
level: relevance.label,
confidence: relevance.prob
},
summary: summary?.text || null,
testCases
};
}
private async extractEntities(text: string): Promise<Array<{ type: string; value: string }>> {
// Use entity extractor to find entities
const sentences = text.split(/[.!?]+/);
const entities: Array<{ type: string; value: string }> = [];
for (const sentence of sentences.slice(0, 20)) { // Limit for performance
const preds = this.entityExtractor.predict(sentence, 3);
if (preds[0].prob > 0.5) {
entities.push({
type: preds[0].label,
value: sentence.substring(0, 50) // Simplified
});
}
}
return entities;
}
private chunkDocument(content: string): Chunk[] {
// Split document into chunks
const paragraphs = content.split(/\n\n+/);
return paragraphs.map((para, i) => ({
heading: `Paragraph ${i + 1}`,
content: para,
score_base: 0.5
}));
}
private async generateTestCases(docType: string, count: number): Promise<string[]> {
const cases: string[] = [];
for (let i = 0; i < count; i++) {
const company = await this.synth.generate('company_name');
const date = await this.synth.generate('date');
cases.push(`${docType} document: ${company} - ${date}`);
}
return cases;
}
}
```
**Why This Architecture Works**:
1. **Entity Extraction (ELM)**: Fast, efficient for named entity recognition
2. **Type Classification (KELM/ELM Ensemble)**: Combines linear and non-linear patterns for accurate classification
3. **Relevance Assessment (ELM Chain)**: Hierarchical feature learning for nuanced relevance scoring
4. **Summary Generation (Pro)**: Production-grade summarization with reranking
5. **Test Case Generation (Synth)**: Privacy-safe synthetic data for testing
**Business Value**:
- **Accuracy**: Ensemble methods reduce classification errors
- **Efficiency**: Chaining allows specialized models at each stage
- **Scalability**: Each stage can be optimized independently
- **Maintainability**: Clear separation of concerns

## Integration Examples
### Integration with React
```typescript
import { useState, useEffect } from 'react';
import { rerankAndFilter, summarizeDeterministic } from '@astermind/astermind-pro';
function SearchComponent() {
const [query, setQuery] = useState('');
const [results, setResults] = useState<ScoredChunk[]>([]);
const [summary, setSummary] = useState('');
const [loading, setLoading] = useState(false);
const handleSearch = async () => {
setLoading(true);
try {
// Rerank
const reranked = rerankAndFilter(query, documents, {
lambdaRidge: 1e-2,
probThresh: 0.45,
useMMR: true,
budgetChars: 1200
});
setResults(reranked);
// Summarize
const summaryResult = summarizeDeterministic(query, reranked, {
maxAnswerChars: 1000,
includeCitations: true
});
setSummary(summaryResult.text);
} finally {
setLoading(false);
}
};
return (
<div>
<input value={query} onChange={e => setQuery(e.target.value)} />
<button onClick={handleSearch}>Search</button>
{loading && <div>Loading...</div>}
{summary && (
<div>
<h3>Summary</h3>
<p>{summary}</p>
</div>
)}
{results.map((result, i) => (
<div key={i}>
<h4>{result.heading}</h4>
<p>Relevance: {(result.p_relevant * 100).toFixed(1)}%</p>
<p>{result.content.slice(0, 200)}...</p>
</div>
))}
</div>
);
}
```
### Integration with Node.js API
```typescript
import express from 'express';
import { rerankAndFilter, summarizeDeterministic } from '@astermind/astermind-pro';
const app = express();
app.use(express.json());
app.post('/api/search', async (req, res) => {
const { query, documents } = req.body;
try {
// Rerank
const reranked = rerankAndFilter(query, documents, {
lambdaRidge: 1e-2,
probThresh: 0.45,
useMMR: true,
budgetChars: 1200
});
// Summarize

});
} catch (error) {
res.status(500).json({ error: error.message });
}
});
app.listen(3000);
```

## Performance Optimization
### 1. Batch Processing
```typescript
// Process multiple queries in batch
async function batchProcess(
queries: string[],
documents: Chunk[]
): Promise<Array<{ query: string; results: ScoredChunk[] }>> {
// Pre-compute document features once
const docFeatures = documents.map(doc =>
computeFeatures(doc)
);
// Process queries in parallel
const results = await Promise.all(
queries.map(async query => {
const queryFeatures = computeFeatures({ content: query });
const reranked = rerank(query, documents, {
lambdaRidge: 1e-2
});
return { query, results: reranked };
})
);
return results;
}
```
### 2. Caching
```typescript
class CachedPipeline {
private cache = new Map<string, ScoredChunk[]>();
async process(query: string, documents: Chunk[]) {
const cacheKey = this.getCacheKey(query, documents);
if (this.cache.has(cacheKey)) {
return this.cache.get(cacheKey)!;
}
const results = rerankAndFilter(query, documents, {
lambdaRidge: 1e-2
});
this.cache.set(cacheKey, results);
return results;
}
private getCacheKey(query: string, docs: Chunk[]): string {
return `${query}:${docs.length}:${docs.map(d => d.heading).join(',')}`;
}
}
```
### 3. Incremental Updates
```typescript
// Use OnlineRidge for incremental learning
class IncrementalReranker {
private ridge: OnlineRidge;
constructor() {
this.ridge = new OnlineRidge(64, 1, 1e-3);
}
update(features: Float64Array, relevance: number) {
this.ridge.update(features, new Float64Array([relevance]));
}
score(features: Float64Array): number {
return this.ridge.predict(features)[0];
}
}
```

## Advanced ELM Variants
### DeepELMPro - Improved Deep ELM
**Key Improvements over Base DeepELM:**
1. **Autoencoder Pretraining** - Each layer can be pretrained as an autoencoder for better feature learning
2. **Layer-wise Training** - Sequential layer training for more stable learning (base DeepELM only supports joint training)
3. **Regularization** - L1/L2/Elastic Net regularization to prevent overfitting (not in base DeepELM)
4. **Batch Normalization** - Optional normalization between layers for faster convergence (not in base DeepELM)
5. **Dropout** - Optional dropout with configurable rate to reduce overfitting (not in base DeepELM)
6. **Flexible Training** - Choose between layer-wise or joint training modes (base DeepELM is joint-only)
**Example Usage:**
```typescript
import { DeepELMPro } from '@astermind/astermind-pro';
// Create DeepELMPro with advanced features
const deepElm = new DeepELMPro({
layers: [256, 128, 64], // Three hidden layers
categories: ['positive', 'negative', 'neutral'],
activation: 'relu',
useDropout: true,
dropoutRate: 0.2,
useBatchNorm: true,
regularization: {
type: 'l2',
lambda: 0.0001,
},
layerWiseTraining: true,
pretraining: true, // Enable autoencoder pretraining
maxLen: 100,
});
// Train with improved strategies
await deepElm.train(X, y);
// Predict
const predictions = deepElm.predict(query, 3);
```
**When to Use DeepELMPro vs Base DeepELM:**
- Use **DeepELMPro** when you need better generalization, have overfitting issues, or want more training control
- Use **Base DeepELM** for simpler use cases where basic multi-layer learning is sufficient
---
## Best Practices
1. **Start Simple**: Begin with basic reranking, then add complexity
2. **Monitor Quality**: Use Transfer Entropy to monitor pipeline health
3. **Tune Gradually**: Adjust parameters incrementally
4. **Cache Aggressively**: Cache expensive computations
5. **Batch When Possible**: Process multiple items together
6. **Use Production Worker**: For inference-only deployments
7. **Validate Inputs**: Check data quality before processing
8. **Handle Errors**: Gracefully handle edge cases
---
## Troubleshooting
### Low Relevance Scores
- Increase `probThresh` in reranking
- Adjust `queryWeight` in summarization
- Check input data quality
### Poor Diversity
- Increase `mmrLambda` in MMR filtering
- Adjust `budgetChars` to allow more content
### Slow Performance
- Use production worker for inference
- Enable caching
- Reduce `randomProjDim`
- Batch process queries
