Attention on SNLI

Unofficial implementation algorithms of attention models on SNLI dataset.

Current include papers:

1. “Reasoning About Entailment With Neural Attention”, arXiv:1509.06664
2. “Learning Natural Language Inference with LSTM”, arXiv:1512.08849

Based on Lasagne.

Requirements

• Cuda 8(Theano can run with)
• Python 3
• Lasagne
• some others(best install Anaconda)

Run

At source root dir

First extracts preprocessed SNLI data
./extract_data.sh

Then run:
python3 ./snli_reasoning_attention.py [condition|attention|word_by_word]

Or run:
python3 ./snli_match_lstm.py

Results

The learning curve of word by word attention(best test acc is at epoch 41):

Epoch: 1-20

Epoch: 20-39

Epoch: 40-59

The learning curve of match LSTM with word embedding:

Notes

About word by word attention:

1. The test acc of word by word attention is 0.2% smaller than the original paper, 83.29% (41 epochs)
2. every 20 epochs, we reduce learning_rate, see log files for detail info.

About match LSTM:

1. The test acc of match LSTM is 1% smaller than the original paper.
2. not decay learning rate when train
3. using Word2Vec pre-trained model
4. tune OOV words in train dataset, like in Reasoning Attention
