This video presents Markov Chain Monte Carlo (MCMC) by first reviewing standard Monte Carlo and building up concepts via Importance Sampling (Importance Weights) and Accept/Reject Sampling (using Importance Weights and Uniform random variables to remove samples) before using said concepts to truly understand the MCMC algorithms: Metropolis-Hastings and Hamiltonian Monte Carlo.
