This is a self-implemented repository for the paper Logistic matrix factorization for implicit feedback data.

Moreover, I've implemented the log confidence function besides linear confidence function.

Requirements

Python                    3.8.13
NumPy                     1.23.1
PyTorch                   1.10.2

The code runs well with these requirements. While the code is simple, I believe it will also run well with some higher or lower versions of these packages.

Usage

Usage is simple, just run:

python entry.py

then everything goes well.
