Abstract :
A new learning algorithm based on Gibbs sampling to learn the parameters of continuous Hidden Markov Models (HMMs) with multivariate Gaussian mixtures is presented. The proposed sampling algorithm outperformed the standard expectation-maximization (EM) algorithm and a minimum classification error algorithm when applied to a synthetic data set. The proposed algorithm outperforms the state of the art when applied to landmine detection using ground penetrating radar (GPR) data.
