#Hidden markov model matlab code code
There's hmmlearn ( ) Python package to fit sequences to HMM, and there's existing Python package to implement SOM (self-organizing maps, such as this one ), but I wonder if there's existing code to implement clustering algorithms for sequential data points, based on updating the distance metric of HMM's likelihood function (or negative log likelihood, etc)? It can be Python, R, Java, Matlab, or Scala, or any other languages. Unlike other books on the subject, it is generic and does not focus on a specific theme, e.g.

I haven't found existing package or code that implements the above clustering algorithms. This book presents, in an integrated form, both the analysis and synthesis of three different types of hidden Markov models. Then on the 2D self-organizing map, K-means is used to cluster the map's nodes. The paper is quite relevant to 1), as it maps each high-dimensional sequences (each sequence may have different length or in other words different dimension) to a 2D map (self organizing maps) where the distance metric is no longer Euclidean distance as that present in the conventional Kohonen Self-Organizing Maps, but instead the distance metrics becomes the log likelihood of how each sequence fits in a candidate hidden Markov model (HMM).
