Hierarchical clustering of a mixture model
WebCluster analysis, also called segmentation analysis or taxonomy analysis, is a common unsupervised learning method. Unsupervised learning is used to draw inferences from data sets consisting of input data without labeled responses. For example, you can use cluster analysis for exploratory data analysis to find hidden patterns or groupings in ... WebResults for the estimated number of data clusters .

Mixture models, however, are often involved in other learning processes whose goals extend beyond simple density estimation to hierarchical clustering, grouping of discrete categories or model simplification. In
