Web7. I'm learning the GMM clustering algorithm. I don't understand how it can used as a classifier. Here are my thought: 1) GMM is an unsupervised ML algorithm. At least that's how sklearn categorizes it. 2) Unsupervised methods can cluster data, but can't make predictions. However, sklearn's user guide clearly applid GMM as a classifier to the ...
