Abstract

The efficiency of resources is the footstone for building prognostics and health management system or safety system. In this study, we proposed an efficient bicluster mining algorithm: CeCluster algorithm, which mines trend bicluster in real-valued resource effectiveness matrices. To improve the mining efficiency, CeCluster algorithm mines maximal trend bicluster using the method of column extension and multiple pruning strategies without candidate maintenance. CeCluster algorithm can not only mine resource patterns with effectiveness in the downtrend, but also mine those with effectiveness in the uptrend. CeCluster algorithm can also mine resource patterns without change of effectiveness. The experimental result shows our algorithm is efficient than traditional algorithm.
