Markov Chains are widely used in various machine learning applications, particularly in modeling sequential or time-series data where the assumption of the Markov Property is reasonable.

Hidden Markov Models

A Hidden Markov Model is a statistical model where the system being modeled is assumed to follow a Markov process with unobserved (hidden) states. HMMs are used in tasks such as speech recognition, natural language processing (NLP), and bioinformatics.

Reinforcement Learning

In Reinforcement Learning (RL), the environment is often modeled as a Markov Decision Process (MDP), which is an extension of a Markov Chain. An MDP includes actions and rewards, where an agent interacts with an environment to maximize cumulative rewards.

Monte Carlo Markov Chain

MCMC methods are used to generate samples from a probability distribution by constructing a Markov Chain that has the desired distribution as its stationary distribution. These samples can be used in Bayesian inference, which is crucial in many machine learning algorithms.
