Which method is used to estimate the parameters of a Gaussian mixture model?

The parameters of GMM are estimated using the iterative expectation–maximization (EM) algorithm (Redner and Walker, 1984).

Which approach is used by Gaussian mixture models?

The GaussianMixture object implements the expectation-maximization (EM) algorithm for fitting mixture-of-Gaussian models.

What is a Gaussian mixture model What is it used for?

Gaussian mixture models (GMMs) are a type of machine learning algorithm. They are used to classify data into different categories based on the probability distribution. Gaussian mixture models can be used in many different areas, including finance, marketing and so much more!

What algorithm is used in GMM?

EM algorithm in GMM

These two steps are repeated until convergence is reached. In this way, a switch between the E-step and the M-step is possible, according to the randomly initialized parameters.
