Clustering subgaussian mixtures by semidefinite programming
We introduce a model-free relax-and-round algorithm for k-means clustering based on a semidefinite relaxation due to Peng and Wei [PW07]. The algorithm interprets the SDP output as a denoised version of the original data and then rounds this output to a hard clustering. We provide a generic method for proving performance guarantees for this algorithm, and we analyze the algorithm in the context...
متن کاملRobustness of SDPs for Partial Recovery of Clustering Subgaussian Mixtures
In this paper, we examine the robustness of a relax-and-round k-means clustering procedure, a method for clustering subgaussian mixtures using semidefinite programming first introduced in [MVW16]. We are interested in the robustness of the algorithm when there is an adversarial corruption of N points each through distance at most R0. We show that under such corruption this specific algorithm we...
متن کاملEnsemble Clustering using Semidefinite Programming
We consider the ensemble clustering problem where the task is to 'aggregate' multiple clustering solutions into a single consolidated clustering that maximizes the shared information among given clustering solutions. We obtain several new results for this problem. First, we note that the notion of agreement under such circumstances can be better captured using an agreement measure based on a 2D...
متن کاملGuaranteed clustering and biclustering via semidefinite programming
Identifying clusters of similar objects in data plays a significant role in a wide range of applications. As a model problem for clustering, we consider the densest k-disjoint-clique problem, whose goal is to identify the collection of k disjoint cliques of a given weighted complete graph maximizing the sum of the densities of the complete subgraphs induced by these cliques. In this paper, we e...
متن کاملInformation Theoretical Clustering via Semidefinite Programming
We propose techniques of convex optimization for information theoretical clustering. The clustering objective is to maximize the mutual information between data points and cluster assignments. We formulate this problem first as an instance of max k cut on weighted graphs. We then apply the technique of semidefinite programming (SDP) relaxation to obtain a convex SDP problem. We show how the sol...
