An implementation of the CNN model described in "A Convolutional Neural Network for Modelling Sentences". Kalchbrenner et al. 2014. Here is the original code in MATLAB.
I referred to https://github.com/FredericGodin/DynamicCNN for implementation hints. The model I implemented however, is very specific to the experiments described in the paper.
Due to unavailability of a high-end GPU, one epoch of training took ~4 hours and this achieved an accuracy of ~78% on the test set of Stanford Sentiment Treebank. The authors reported an accuracy of 86.8 % by a well-trained model in the paper.
