SpaMHMM: Sparse Mixture of Hidden Markov Models for Graph Connected Entities

Machine Learning 2019-04-02 v1 Machine Learning

Abstract

We propose a framework to model the distribution of sequential data coming from a set of entities connected in a graph with a known topology. The method is based on a mixture of shared hidden Markov models (HMMs), which are jointly trained in order to exploit the knowledge of the graph structure and in such a way that the obtained mixtures tend to be sparse. Experiments in different application domains demonstrate the effectiveness and versatility of the method.
