The fuzzyK-means problem is a popular generalization of the well-knownK-means problem to soft clusterings. In this article, we present the first algorithmic study of the problem going beyond heuristics. Our main result is that, assuming a constant number of clusters, there is a polynomial time approximation scheme for the fuzzyK-means problem. As a part of our analysis, we also prove the existence of small coresets for fuzzyK-means. At the heart of our proofs are two novel techniques developed to analyze the otherwise notoriously difficult fuzzyK-means objective function.
