The Baum--Welch algorithm is used for computing maximum likelihood estimates and posterior mode estimates for the parameters (transition and emission probabilities) of a HMM, when given only output sequences (emissions) as training data.
The Baum--Welch algorithm is a particular instantiation of the expectation-maximization algorithm, suited for HMMs.
