spectralcluster

Python re-implementation of the (constrained) spectral clustering algorithms used in Google's speaker diarization papers.

clumppy

Clustering algorithms

synloc

A Python package to create synthetic data from locally estimated distributions

constrained-linkage

Python implementation of a (plug-and-play) constrained linkage function for constrained hierarchical clustering with maximum cluster size, minimum cluster size, must-link, cannot-link and custom constraints, returns SciPy-compatible linkage matrix for subsequent Hierarchical Agglomerative Clustering. Based on HEAT published in Energy and AI (2025)

scikit-query
