MachineLearning in Haskell
==========================

This is a library implementing some basic machine learning algorithms.

## Hopfield Networks ##

To run the demonstration, run
`MachineLearning/HopfieldDemonstration.hs`.  It demonstrates the
training of a network on an `O` and an `X`, and shows the network
reconstructing the trained patterns from a perturbed version.
