You can do this in matlab by using the hmmdecode command (I guess, I have never done this before, but according to the documentation, it returns the forward probabilities). ACM Reference Format: Andreas Bulling, Ulf Blanke, and Bernt Schiele. According to the last image, it is better to use either the Forward or the Backward algorithm. The probability over the best Viterbi path is a "cheap" alternative to the real solution. You want to see which out of 2 models scores higher:īecause i've used two hmms for each obsv sequence and i want to see which hmm is the winner or best matches. This will give you a score, for sure, but I am not convinced if this is the best solution for the second part of your question. Where you simply have to multiply the emission and the transition probabilities. given a model $M$, a single path $π$ and a set of observations $x$, what is the actual joint probability of the path and the observations, if we know the model? You are trying to solve this:

This looks like you are asking for a solution to problem 1 here, i.e. I did solve this the code can be found on my GitHub. Is there any way to derive the probability (score) of this calculated state sequence from the hmmviterbi code available in matlab or any other algorithm? I think you might be confusing 2 separate things here, but have a look at the following images before I try to explain my thinking and focus on the Scoring rows: Search for jobs related to Hidden markov model matlab source code or hire on the worlds largest freelancing marketplace with 20m+ jobs.
