What is hmm meaning?

HMM stands for Hidden Markov Model which is a statistical model used in machine learning and computational linguistics. HMM is a type of probabilistic model that predicts future states or events based on past observations. It is based on the assumption that each observation is generated by one of several hidden states, and the probability of transitioning from one state to another is known. HMM is widely used in speech recognition, natural language processing, and biological sequence analysis applications.
