Library "FunctionProbabilityViterbi"
The Viterbi Algorithm calculates the most likely sequence of hidden states *(called Viterbi path)*
that results in a sequence of observed events.
viterbi(observations, transitions, emissions, initial_distribution)
Calculate most probable path in a Markov model.
Parameters:
observations (int[]): array<int> . Observation states data.
transitions (matrix<float>): matrix<float> . Transition probability table, (HxH, H:Hidden states).
emissions (matrix<float>): matrix<float> . Emission probability table, (OxH, O:Observed states).
initial_distribution (float[]): array<float> . Initial probability distribution for the hidden states.
Returns: array<int>. Most probable path.

Minor update: console library version.Nota Keluaran
v4 - added some error overloads with custom message to handle some cases.Nota Keluaran
v5 - updated the description of the function to fix a typo, thanks to serkany88 for catching the little bugger :pUpdated:
