## About

Highly configurable t-SNE implementation for arbitrary dimensions.

Current implementation (as of 07/2021) is based in principle on:

- https://github.com/karpathy/tsnejs

Most key functionality has been refactored/rewritten to use pre-existing
functionality provided by other thi.ng packages.

~~Furthermore, this implementation has been extended to use
https://thi.ng/geom-accel to optimize spatial lookups~~. (FIXME currently
disabled/removed again)

## Status

**ALPHA** - bleeding edge / work-in-progress

[Search or submit any issues for this package](https://codeberg.org/thi.ng/umbrella/issues?q=%5Btsne%5D)

## Installation

```bash
yarn add @thi.ng/tsne
```

ESM import:

```ts
import * as tsne from "@thi.ng/tsne";
```

Browser ESM import:

```html
<script type="module" src="https://esm.run/@thi.ng/tsne"></script>
```

[JSDelivr documentation](https://www.jsdelivr.com/)

For Node.js REPL:
