A Survey: Clustering Ensembles Techniques

The clustering ensembles combine multiple partitions generated by different clustering algorithms into a single clustering solution. Clustering ensembles have emerged as a prominent method for improving robustness, stability and accuracy of unsupervised classification solutions. So far, many contributions have been done to find consensus clustering. One of the major problems in clustering ensembles is the consensus function. In this paper, the authors introduce clustering ensembles, representation of multiple partitions, its challenges and present taxonomy of combination algorithms. They describe consensus functions in clustering ensembles including Hyper-graph partitioning, Voting approach, Mutual information, Co-association based functions and Finite mixture model, and next explain their advantages, disadvantages and computational complexity.
