Unequal length observation sequences when training Hidden Markov model?

25 March 2019 1 8K Report

For example if:

states = ('Rainy','Sunny') observations = ('walk', 'shop', 'clean') For example if:

observation 1 = ('walk', 'shop', 'clean') observation 2 = ('walk', 'shop', 'clean','eat pizza') observation 3 = ('walk', 'shop', 'clean','drink beer','eat pizza') ...so on

What's the size of emission probability matrix in this case? Or can I just make the observation sequence the same length by padding with zeros?

Dear Muhamamd Shuaib Aslam

Size of emission vector equals to the size of largest observation vector. In other word, the emission vector is the codebook that includes all the possibility values; either numerical values or words.
