Description
This utility takes an already-trained HMM, specified as '--input_model_file (-m)', and evaluates the most
probable hidden state sequence of a given sequence of observations (specified as ''--input_file (-i)',
using the Viterbi algorithm. The computed state sequence may be saved using the '--output_file (-o)'
output parameter.
For example, to predict the state sequence of the observations 'obs.csv' using the HMM 'hmm.bin', storing
the predicted state sequence to 'states.csv', the following command could be used:
$ mlpack_hmm_viterbi--input_file obs.csv --input_model_file hmm.bin --output_file states.csv
