Lloyd's algorithm clustering consistency proven under perturbed samples

Researchers have analyzed the consistency of Lloyd's algorithm, a popular unsupervised clustering method, when applied to perturbed data. They demonstrated that even with small perturbations, the algorithm maintains an exponential bound on its mis-clustering rate after logarithmic iterations, provided proper initialization. This theoretical guarantee extends to pipelines that measure statistical significance of derived clusters, offering implications for applications like spectral clustering in network analysis and time series analysis.
