# Bayesian inference; How we are able to chase the Posterior

## June 10, 2019

Bayesian modeling! Every introduction on that topic starts with a quick conclusion that finding the posterior distribution often is computationally intractable. Last post I looked at Expectation Maximization, which is a solution of this computational intractability for a set of models. However, for most models, it isn’t. This post I will take a formal definition of the problem (As I’ve skipped that in the Expectation Maximization post) and we’ll look at two solutions that help us tackle this problem; Markov Chain Monte Carlo and Variational Inference.
