A Sparse PCA Approach to Clustering

Methodology 2016-02-18 v1 Machine Learning

Abstract

We discuss a clustering method for Gaussian mixture model based on the sparse principal component analysis (SPCA) method and compare it with the IF-PCA method. We also discuss the dependent case where the covariance matrix Σ\Sigma is not necessarily diagonal.
