It gives the first hidden state’s probability distribution definition. Speech recognition, natural language processing, bioinformatics (for gene prediction), and finance (for stock price modeling) are just a few of the fields in which HMMs find usage. HMMs are frequently trained using the Baum-...
Then, an Hidden Markov Model is defined by states, state probabilities, transition probabilities, emission probabilities and initial probabilities. They constitute the architecture of an HMM. Formalizing the definition, an HMM is a quintuple (S, V,π, A, B), characterized by the following ...
