Visualizing and Understanding Neural Models in NLP

Implementations of saliency models described in "Visualizing and Understanding Neural Models in NLP" by Jiwei Li, Xinlei Chen, Eduard Hovy and Dan Jurafsky.

Requirements:

GPU

Torch (nn,cutorch,cunn,nngraph)

python matplotlib library (only for matrix plotting purposes)

download data

Run the models:

Run the first-derivative saliency model:

sh saliency_derivative.sh

The saliency matrix will be stored in the file "matrix".

Run the variance saliency model:

sh saliency_variance.sh

The saliency matrix will be stored in the file "matrix".

##Folders and Files input.txt: the input sentence.

sentiment_bidi: training bi-directional lstms on the Stanford Sentiment Treebank. You can either download a pretrained model (sentiment_bidi/model) or train it yourself by running sentiment_bidi/main.lua

sentiment_uni: training uni-directional standard recurrent models.

data/dict.txt: word dictionary. Current models only support tokens found in the dictionary. Will fix it soon.
