# Structured Self-attentive sentence embeddings 

Implementation for the paper A Structured Self-Attentive Sentence Embedding, which was published in ICLR 2017: https://arxiv.org/abs/1703.03130 .

#### USAGE:

For binary sentiment classification on imdb dataset run :

`python classification.py "binary"`

For multiclass classification on reuters dataset run :

`python classification.py "multiclass"`

You can change the model parameters in the `model_params.json file`

Other tranining parameters like number of attention hops etc can be configured in the `config.json` file.

If you want to use pretrained glove embeddings , set the `use_embeddings` parameter to `"True"` ,default is set to False. Do not forget to download the `glove.6B.50d.txt` and place it in the glove folder.

#### Implemented:

* Classification using self attention

* Regularization using Frobenius norm

* Gradient clipping

* Visualizing the attention weights

Instead of pruning ,used averaging over the sentence embeddings.

#### Visualization:

After training, the model is tested on 100 test points. Attention weights for the 100 test data are retrieved and used to visualize over the text using heatmaps. A file visualization.html gets saved in the visualization/ folder after successful training. The visualization code was provided by Zhouhan Lin (@hantek). Many thanks.

Below is a shot of the visualization on few datapoints.

Training accuracy 93.4%

Tested on 1000 points with 90.2% accuracy
