Gaussian Mixture Model (GMM) for clustering - calculate AIC/BIC
In this video, I tried to implement Gaussian Mixture Model (GMM) for clustering using Scikit-Learn. Gaussian Mixture Models (GMMs) assume that a certain number of Gaussian distributions exist within a dataset. Therefore, each Gaussian distribution represents a particular cluster. We can also calculate AIC (Akaike Information Criterion) and BIC (Bayesian Information Criterion) in GMM clustering to determine the best fit.
