A hidden Markov model (HMM) is a statistical Markov model in which the system being modeled is assumed to be a Markov process — call it $${\displaystyle X}$$ — with unobservable ("hidden") states. As part of the definition, HMM requires that there be an observable process $${\displaystyle Y}$$ whose … See more Let $${\displaystyle X_{n}}$$ and $${\displaystyle Y_{n}}$$ be discrete-time stochastic processes and $${\displaystyle n\geq 1}$$. The pair $${\displaystyle (X_{n},Y_{n})}$$ is a hidden Markov model if See more Several inference problems are associated with hidden Markov models, as outlined below. Probability of an observed sequence The task is to compute in a best way, given the parameters of the model, the probability of a … See more HMMs can be applied in many fields where the goal is to recover a data sequence that is not immediately observable (but other data that depend on the sequence are).
