How to make it work: 1. Create a separate directory and download all these files into the same directory 2. Download the following 7 files: * demo.m Main file for training PMF and Bayesian PMF * pmf.m Training PMF model * bayespmf.m Bayesian PMF model that implements Gibbs sampler. * moviedata.mat Sample data that contains triplets (user_id, movie_id, rating) * makematrix.m Helper function that converts triplets into large matrix. This file is used by bayespmf.m * pred.m Helper function that makes predictions on the validation set. * README.txt 3. Simply run demo.m in Matlab. It will fit PMF and then will run Bayesian PMF. This code uses Matlab stats toolbox to sample Wishart distribution.
