'''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. | |
