Artifact-free screen scaling for a canvas game, limited to 1X, 2X, 4X
// Adapted from Zachary Johnson's Commander Clone 0.2 screen scaling example http://www.zachstronaut.com/projects/commander-clone/0.2/game.html
// Modified to strictly choose 1X or 2X or 4X scaling as appopriate, so we don't end up with screwed up scaling artifacts.
// NOTE: uses jQuery for the DOM load event

Keras implementation of Kim's paper "Convolutional Neural Networks for Sentence Classification" with a very small embedding size. The test accuracy is 0.853.
'''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.
