BPTF Tutorial

Bayesian Poisson Tensor Factorization

This project includes the detailed derivations and a Python code for the tensor factorization with Poisson observations. The code is written using Numpy, Scipy and Tensorly libraries.

How to run tests:

You can run the tests from the main directory using nosetests.

• nosetests --nocapture test/test_nmf.py
• nosetests --nocapture test/test_parafac.py
• nosetests --nocapture test/test_bptf.py
