DCEM

Clustering Big Data using Expectation Maximization Star (EM*) Algorithm

v2.0.6 · Apr 14, 2026 · GPL-3

Description

Implements the Improved Expectation Maximisation EM* and the traditional EM algorithm for clustering big data (gaussian mixture models for both multivariate and univariate datasets). This version implements the faster alternative-EM* that expedites convergence via structure based data segregation. The implementation supports both random and K-means++ based initialization.
