# When using Gaussian mixture model, how do you know it is applicable

Upasana | May 24, 2019 | 1 min read | 3 views

**Answer** :

Assumption we take before applying Gaussian Mixture Model is that data points must be Gaussian distributed means their probability distribution must be Gaussian Distribution which means, We won’t be taking only mean into consideration but standard deviation as well of each cluster.

For optimizing this model, EM (Expectation Maximization) algorithm is used.
