Lloyd's K-Means Algorithm Identified as Special Case of Frank-Wolfe Method

By PulseAugur Editorial · [1 sources] ·

A new paper establishes a connection between Lloyd's K-Means Clustering Algorithm and the Frank-Wolfe (FW) algorithm, demonstrating that K-Means is a specific instance of FW. This research derives a non-asymptotic convergence rate for K-Means and proposes an FW variant to handle empty clusters, retaining the same convergence rate. The findings are illustrated with simulations on Gaussian mixtures and image segmentation data. AI

IMPACT Provides a theoretical framework that could lead to improved optimization methods for clustering tasks in machine learning.

    Lloyd's $K$-Means Clustering Algorithm Is Frank-Wolfe in Disguise

    arXiv:2607.25190v1 Announce Type: new Abstract: Lloyd's $K$-means algorithm, also known as na\"{i}ve $K$-means, is a widely used ad hoc optimization heuristic, designed to minimize the sum of squared errors (SSE) across all $K$-partitions of a dataset via iterative cluster refine…
