WebMar 20, 2024 · Adapted from HMM/NLP lectures by James Kunz et al @UC Berkeley Overview. Hidden Markov Models (HMMs) are a class of probabilistic graphical model that allow us to predict a sequence of … 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). Applications include: • Computational finance • Single-molecule kinetic analysis See more Drawing balls from hidden urns In its discrete form, a hidden Markov process can be visualized as a generalization of the See more The diagram below shows the general architecture of an instantiated HMM.

The first is the HMM transition matrix, which contains the probabilities of switching from one state to another.
