I want to use Viterbi algorithm, to decode an HMM sequence, but very few observations are missing in some of the steps or outliers. The hidden states in these steps are assumed to be the same as their previous states (or their adjacent states).

Can anyone tell me how can I set the emission probability in these steps. If I were to use Baum-Welch algorithm, what should I do.?

Thanks

What should be done to deal with missing observations ( or outlier observation ) for Viterbi?
