A convergence theorem for the fuzzy subspace clustering (FSC) algorithm

摘要

We establish the convergence of the fuzzy subspace clustering (FSC) algorithm by applying Zangwill's convergence theorem. We show that the iteration sequence produced by the FSC algorithm terminates at a point in the solution set S or there is a subsequence converging to a point in S. In addition, we present experimental results that illustrate the convergence properties of the FSC algorithm in various scenarios. (C) 2007 Elsevier Ltd. All rights reserved.
