Hierarchical Attention Networks

Implementation of Hierarchical Attention Networks for Documnet Classification HAN (2016) with PyTorch and Torchtext.

To run the model on Reuters dataset on static, just run the following from the project working directory.

python -m models.han --dataset Reuters --mode static --batch-size 32 --lr 0.01 --epochs 30 --seed 3435

The best model weights will be saved in

models/han/saves/Reuters/best_model.pt

To test the model, you can use the following command.

python -m models.han --dataset Reuters --mode static --batch-size 32 --trained-model models/han/saves/Reuters/best_model.pt --seed 3435

rand: All words are randomly initialized and then modified during training.
static: A model with pre-trained vectors from word2vec. All words -- including the unknown ones that are initialized with zero -- are kept static and only the other parameters of the model are learned.
non-static: Same as above but the pretrained vectors are fine-tuned for each task.

We experiment the model on the following datasets.

Adam is used for training.
