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.
You can find the detailed derivations of the BPTF model in bptf.pdf
- NMF: Poisson NMF implementation
- Parafac: Parafac solver with Alternating Least Squares
- BPTF: Bayesian Poisson Tensor Factorization implementation
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
