Bagging-Based Selective Clusterer Ensemble

Abstract

This paper uses ensemble learning technique to improve clustering performance. Since the training data used in clustering lacks the expected output, the combination of component learner is more difficult than that under supervised learning. Through aligning different clustering results and selecting component learners with the help of mutual information weight, this paper proposes a Bagging-based selective clusterer ensemble algorithm. Experiments show that this algorithm could effectively improve the clustering results.
