Abstract
An apparatus includes processing circuitry configured to execute instructions that, when executed, cause the apparatus to initialize a mixture model having a number of clusters including categorical data, iteratively update cluster assignments, evaluate cluster quality based on categorical density of the clusters, and prune clusters that have low categorical density, and determine an optimal mixture model based on the pruned clusters.
