MST-kNN Clustering Algorithm

v1.0.0 · May 13, 2026 · GPL-2

Description

Implements the MST-kNN clustering algorithm proposed by Inostroza-Ponta (2008) <https://trove.nla.gov.au/work/28729389>. The algorithm determines the number of clusters automatically by recursively intersecting the Minimum Spanning Tree (MST) and the k-Nearest Neighbor (kNN) proximity graphs constructed from a pairwise distance matrix. The value of k is selected via a connectivity criterion (the smallest k such that the kNN graph is connected, bounded by floor(log(n))). The package requires only a distance matrix as input and returns cluster assignments, an 'igraph' network, and partition metadata.
