Promoss topic modelling toolbox.
This java project contains all my recent topic models I am developing since 2016, including the multi-context topic model described in my dissertation.
Multi-Dirichlet Process Geographical Topic Model (MGTM).
My first implementation of a Multi-Dirichlet Process (MDP) topic model, which uses a collapsed Gibbs sampler. This model yields nice topics, but gets stuck in local optima. I still use this model if I want to detect a low number of human-interpretable topics. However, if you want to have perfect results and a faster inference, use the multi-context topic model of the Promoss toolbox.
