Abstract

Using information entropy or fuzzy entropy to determine the different features of each cluster for subspace clustering

subspace clustering for high dimensional data is solved very well. For further improving performance of clustering algorithm

negative structural

α‑

entropy with weight vector is introduced into the Gaussian mixture model to obtain a structural

α‑

entropy weighting mixture model of subspace clustering. Based on this

the structural

α‑

entropy weighting mixture model subspace clustering algorithm(SEWMM) is derived theoretically

which can not only discover clusters in different subspaces in high dimensional data space

but also can discover clusters with various shape volumes in subspaces. And convergence and time complexity of algorithm are further analyzed. In the experiment

compared with some representative algorithms

the proposed algorithm SEWMM is tested on UCI(University of California

Irvine) standard data sets and image data sets. It shows the proposed algorithm has a certain improvement in the overall performance.
