Requirements to run the experiments

• Python 3
• NumPy
• sklearn [http://scikit-learn.org/stable/]
• pytorch [http://pytorch.org/]

Usage

First, clone the repo:

git clone https://github.com/jbarnesspain/blse
cd blse

Then, get monolingual embeddings, either by training your own, or by downloading the pretrained embeddings mentioned in the paper, unzipping them and putting them in the 'embeddings' directory:

Run the blse parameter search script, in order to get the best hyperparameters:

python3 parmeter_search.py

Finally, you can use the blse.py script which will automatically use the best hyperparameters found.

python3 blse.py

Update

I have added further experiments comparing our method with MUSE. MUSE outperforms VecMap (version from 2017) on all setups and Barista on the binary setup. BLSE performs better than MUSE on 5 of the 6 setups.
