Predict delays of Berlin public transport vehicles.

# predict-vbb-delays

**Predict delays of Berlin public transport vehicles.** Work in progress, made during [Hamburg Mobility Hackathon 2017](http://mobility-hackathon.de). We generate predictions in multiple stages:

1. **Record departures** with realtime delays, e.g. using [record-vbb-delays](https://github.com/derhuerst/record-vbb-delays#record-vbb-delays).
2. **Transform the data into a training set**, which is just a list of individual data points. Each data point consists of the input vector (one value per feature to be recognized) and a desired output value. `node index.js` will generate an [ndjson](http://ndjson.org) training set.
3. Split the raw training set into **two disjunct sets, one for training, one for auditing** the predictions made later. `node split-into-sets.js` will do this.
4. **Train a neural network**. *More details to be added by @juliuste.*
5. **Generate predictions by applying the trained network** to current realtime departures or future scheduled departures. *Not done yet.*
