RecurrentJava is a reimplementation of Andrej Karpathy's RecurrentJS, in Java.
It currently features:
- Deep Recurrent Neural Networks
- Long Short-Term Memory Networks
- Gated Recurrent Unit Neural Networks
- Backpropagation Through Time handled via Automatic Differentiation.
ExamplePaulGraham.java shows how to do character-by-character sentence prediction and generation.
