We are using Hidden Markov Model to cluster gene expression data where every observation has univariate gaussian emission based on latent state. We have chosen to have three latent states and mean and variance of Gaussian emissions will depend upon cluster and latent state.



We are using completely Bayesian approach for determining various distribution parameters.



Problem:
How to define correlation structure between feature variables (latent states) both within and between clusters.
