This is an LSTM implementation is pure go made with gorgonia.
The documentation is in progress.
By now, you can go get github.com/owulveryck/lstm and then run the example:
cd example/train ; go run ../../data/tontons/input.txt
It will train the LSTM and predict every now and then.
TODO: the Gorgonia API has changed, I may need to asjust the solver when the 0.9 will be released
