forward-backward algorithm
An inference algorithm for hidden Markov models which computes the posterior marginals…An inference algorithm for hidden Markov models which computes the posterior marginals of all hidden state variables given a sequence of observations/emissions. It uses dynamic programming to compute the values in two passes, the first going forward in time and the second backward.
