Expectation–maximization algorithm - Wikipedia
In statistics, an expectation–maximization (EM) algorithm is an iterative method to find (local) maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent variables. The EM iteration alternates between performing an expectation (E) step, which creates a function for the expectation of the log-likelihood evaluated using the current estimate for the parameters, and a maximization (M) step, which computes parameters maximizing th…

Expectation Maximizatio (EM) Algorithm - Duke University
So the basic idea behind Expectation Maximization (EM) is simply to start with a guess for \ (\theta\), then calculate \ (z\), then update \ (\theta\) using this new …
The Expectation-Maximization (EM) algorithm Simply Explained
We repeat this E-step and M-step loop until the values for θA and θB stop changing significantly. At that point, the algorithm has converged, and those are our final estimates.
