Sliced Recurrent Neural Network (SRNN).
SRNN is able to get much faster speed than standard RNN by slicing the sequences into many subsequences.
The code is written in keras, using tensorflow backend. We implement the SRNN(8,2) here, and Yelp 2013 dataset is used.

I update the code to adapt new API version as following:
keras version: 2.2.4
tensorflow version: 2.0.0
python : 3.7
