Web22 jan. 2016 · In this note, we will introduce the expectation-maximization (EM) algorithm in the context of Gaussian mixture models. Let denote the probability distribution function for a normal random variable. In this scenario, we have that the conditional distribution so that the marginal distribution of is: WebThe easiest way is to simply calculate the mean of each variable and substitute that for each of the missing values. The problem with this is that it reduces the variance and the absolute value of the covariance. Another common approach is called Expectation – Maximization.
