Cluster Analysis

The Wolfram Language has broad support for non-hierarchical and hierarchical cluster analysis, allowing data that is similar to be clustered together. There is general support for all forms of data, including numerical, textual, and image data. The system implements efficient versions of both classic and modern machine learning-based clustering analysis methods.
