NAME¶

mlpack_hmm_loglik - hidden markov model (hmm) sequence log-likelihood

SYNOPSIS¶

 mlpack_hmm_loglik -i unknown -m unknown [-V bool] [--log_likelihood double] [-h -v] 

DESCRIPTION¶

This utility takes an already-trained HMM, specified with the ’--input_model_file (-m)' parameter, and evaluates the log-likelihood of a sequence of observations, given with the '--input_file (-i)' parameter. The computed log-likelihood is given as output.

For example, to compute the log-likelihood of the sequence 'seq.csv' with the pre-trained HMM 'hmm.bin', the following command may be used:

$ mlpack_hmm_loglik --input_file seq.csv --input_model_file hmm.bin

REQUIRED INPUT OPTIONS¶

--input_file (-i) [unknown]

File containing observations,

--input_model_file (-m) [unknown]

File containing HMM.

OPTIONAL INPUT OPTIONS¶

--help (-h) [bool]

Default help info.

--info [string]

Print help on a specific option. Default value ''.

--verbose (-v) [bool]

Display informational messages and the full list of parameters and timers at the end of execution.

--version (-V) [bool]

Display the version of mlpack.

OPTIONAL OUTPUT OPTIONS¶

--log_likelihood [double]

Log-likelihood of the sequence. Default value 0.
