Setup GalaXC

git clone https://github.com/Extreme-classification/GalaXC.git
conda env create -f GalaXC/environment.yml
conda activate galaxc
pip install hnswlib
git clone https://github.com/kunaldahiya/pyxclib.git
cd pyxclib
python setup.py install
cd ../GalaXC

Dataset Structure

Your dataset should have the following structure:

DatasetName (e.g. LF-AmazonTitles-131K)
│   trn_X.txt   (text for trn documents, one text in each line)
|   tst_X.tst   (text for tst documents, one text in each line)
|   Y.txt       (text for labels, one text in each line)
│   trn_X_Y.txt (trn labels in spmat format)
|   tst_X_Y.txt (tst labels in spmat format)
|   filter_labels_test.txt (filter labels where label and test documents are same)
│
└───XXCondensedData (embeddings for tst, trn documents and labels, for benchmark datasets, XX=DX[Astec])
    │   trn_point_embs.npy (2D numpy matrix for trn document embeddings)
    │   tst_point_embs.npy (2D numpy matrix for tst document embeddings)
    |   label_embs.npy     (2D numpy matrix for label embeddings)

We have provided the DX(embeddings from Module 1 of Astec) embeddings for public benchmark datasets for ease of use. Got better(higher recall) embeddings from somewhere? Just plug the new ones and GalaXC will have better preformance, no need to make any code change! These files for LF-AmazonTitles-131K, LF-WikiSeeAlsoTitles-320K and LF-AmazonTitles-1.3M can be found here. Except the files in DXCondensedData, all other files are copy of the datasets from The Extreme Classification Repository.
