Hidden Markov Models in python¶ Here we’ll show how the Viterbi algorithm works for HMMs, assuming we have a trained model to start with. We will use the example in the JM3 book (Ch. 8.4.6). In [1]: import numpy as np Initialise the model parameters based on the example from the slides/book (values taken from figure).
