Keras implementation of Kim's paper "Convolutional Neural Networks for Sentence Classification" with a very small embedding size.
'''This scripts implements Kim's paper "Convolutional Neural Networks for Sentence Classification"
with a very small embedding size (20) than the commonly used values (100 - 300) as it gives better
result with much less parameters.
Run on GPU: THEANO_FLAGS=mode=FAST_RUN,device=gpu,floatX=float32 python imdb_cnn.py
Get to 0.853 test accuracy after 5 epochs. 13s/epoch on Nvidia GTX980 GPU.

computer or the gears of a cycle transmission as he does at the top of a mountain
or in the petals of a flower. To think otherwise is to demean the Buddha...which is
to demean oneself."""
