This example uses the Forward algorithm to calculate the probability of an observed sequence.
var HiddenMarkovModel = ;var HMM = ;HMM; // 1. Healthy, 2. FeverHMM;HMM;/* What is the probability that the Hidden Markov Model is able to* generate the observed sequence of being Normal on day 1,* Cold on day2, and Dizzy on day 3?*/var alpha = ;var result = HMM; // Normal, Cold, Dizzyconsole; // 0.03628console;/* [ [ 0.3, 0.04000000000000001 ],[ 0.09040000000000001, 0.0342 ],[ 0.007696000000000001, 0.028584000000000002 ] ]*/
