Poincaré Embeddings for Learning Hierarchical Representations

PyTorch implementation of Poincaré Embeddings for Learning Hierarchical Representations

Example: Embedding WordNet Mammals

To embed the transitive closure of the WordNet mammals subtree, first generate the data via

cd wordnet
make

This will generate the transitive closure of the full noun hierarchy as well as of the mammals subtree of WordNet.

To embed the mammals subtree in the reconstruction setting (i.e., without missing data), go to the root directory of the project and run

NTHREADS=2 ./example.sh

This shell script includes the appropriate parameter settings for the mammals subtree and saves the trained model as mammals.pth.

The embeddings are trained via multithreaded async SGD. In the example above, the number of threads is set to a conservative setting (NHTREADS=2) which should run well even on smaller machines. On machines with many cores, increase NTHREADS for faster convergence.

Installation
