PyOhio 2011: Using pymc to cluster twitter users -- a noob's perspective

Description

Using pymc to cluster twitter users -- a noob's perspective

Presented by Timmy Wilson

Journey through the thoughts, hopes, and sad frustrations of an average python developer trying to understand MCMC matrix factorization. I'll work through a Python implementation of the paper "Bayesian Probabilistic Matrix Factorization using Markov Chain Monte Carlo" and talk about how it applies to clustering a Twitter adjacency matrix.
