I'm very new to the field of AI and HMMs. My question is can HMMs be used to model any time series data? Or does the data have to be that of a Markov process?
In HTK documentation, I see that the first few lines state that it can model any time series ("HTK is a toolkit for building Hidden Markov Models (HMMs). HMMs can be used to model any time series and the core of HTK is similarly general-purpose.")
