3.4 HMM/IOHMM model trainingThe standard Baum-Welch training algorithm for continuous and discrete observations is utilized to train the models, and both AIC and BIC selection criteria are considered for the model order selection. For the case of IOHMM training, the conditional Gaussian distributions are considered to model the output functions for different states. The pseudo code of the training procedure is presented inAlgorithm 1.
