How do you train an hMM model in practice ?

Posted on February 16, 2019May 11, 2019 by InterviewBuddy

The joint probability distribution for the HMM model is given by the following equation where are the observed data points and the corresponding latent(hidden) states:     Before proceeding to answer the question on training a HMM, it makes sense to ask following questions What is the problem in hand for which we are training…

How many parameters are there for an hMM model?

Posted on February 16, 2019May 11, 2019 by InterviewBuddy

Let us calculate the number of parameters for bi-gram hMM given as     Let be the total number of states and be the vocabulary size and be the length of the sequence Before directly estimating the number of parameters, let us first try to see what are the different probabilities or rather probability matrix…
