Abstract:

In this paper, we study the Bregman kappa-means problem with respect to mu-similar Bregman divergences (p-BKMP). Given an n-point set S and kappa <= n, mu-BKMP is to find a center subset C subset of S with vertical bar C vertical bar = k and separate the given set into k clusters accordingly, aiming to minimize the sum of mu-similar Bregman divergences of the points in S to their nearest centers. We propose a new variant of k-means++ by employing the local search scheme, and show the algorithm deserves a constant approximation guarantee.
