Rough set based cluster ensemble selection
Xueen Wang, Deqiang Han, Chongzhao Han · International Conference on Information Fusion · 2013
Ensemble clustering have been attracting lots of attentions, which combining several base data partitions to generate a single consensus partition with improved stability and robustness. Diversity is critical for the success of ensemble clustering. To enhance this characteristic, a subset of cluster ensemble is selected by removing the redundant partitions. Combined with ranking and forward selection strategies, the significance of attribute defined in rough set theory is employed as a heuristic to find the subset of cluster ensemble. Experimental results on the UCI machine learning repository demonstrate that the proposed algorithm is feasible and effective.
