Hidden Markov Model


Video tutorials

Formal definition of a HMM

Simple example showing the difference between hidden and observed states

Introduction of the rough structure of the Forward-Backward algorithm

Forward step: how to compute the probability

Forward step: computational complexity

stresses the low computational complexity of the forward step of THETA(n*m^2), which goes back to the idea of Dynamic Programming (DP = reuse earlier computations)

Backward algorithm

very similar idea to the forward algorithm: setting up a recursion + using the transition + emission probabilities
