Keras implementation of Phased LSTM [https://arxiv.org/abs/1610.09513], from NIPS 2016.
To install run:
`pip install phased_lstm_keras`
Works both with Theano and Tensorflow backend (tested on Theano 0.9 and Tensorflow 1.0).
Classification performance compared to standard Keras LSTM for MNIST dataset:
