## Statistical Inference for Markov and Hidden Markov Models

*19 Sep 2018 10:07*

I am concerned here with inferring the parameters and/or the structure of the model, not with the estimation of the hidden state in a hidden Markov model with known parameters; that problem falls under filtering.

Parameter inference (what machine learning types would call "learning") given a known, fixed structure. Determining the structure ("discovery"). Order estimation as a particular case of discovery, and of model selection. (Discovery may need its own notebook soon.)

Markov models naturally form exponential families; what classes of partially-observable Markov processes also do?

Inference in Hidden Markov Models [This is a superb book, treating
all the main statistical problems connected with HMMs with both clarity and
rigor. There is a chapter/appendix which reminds the reader who has forgotten
about Markov chains on general state spaces, but remembers measure-theoretic
probability
*very well*, about their properties. (The idea that the reader of a book on HMMs may not know what the Viterbi algorithm is, but will*of course*recall the Hahn-Jordan decomposition, strikes me as very much a product of the French school of probability theory — from which I have learned much! But it's not so far gone as to make the whole thing an exercise in the "general theory of processes".)] - Andrew Fraser, Hidden Markov Models and Dynamical Systems [Review: The Statistics of Moving Shadows]
