“…By combining the codes generated by independent runs of LSH, CH 1 obtains a remarkable improvement on LSH, and consistently outperforms other state-of-the-art methods on these datasets. This demonstrates that the performance of weak hashing methods can be largely improved by the proposed consensus strategy, which is consistent with the previous conclusions made in classifier combination (Schapire 1990;Breiman 1996;Breiman 2001) and clustering combination (Monti et al 2003;Li et al 2007;Fred and Jain 2005).…”

“…During the past decades, a great number of consensus clustering approaches have been proposed. Representative works include similarity based methods (Fred and Jain 2005), graph based methods (Fern and Brodley 2004) and non-negative matrix factorization (NMF) based methods (Li et al 2007). Similarity based methods express the base clustering results as similarity matrices and generate the final clustering result based on the consensus similarity matrix (Fred and Jain 2005).…”

“…• Consensus Clustering: Most consensus clustering algorithms are not designed for our setting, where not all the samples are labeled by experts [94]. However, since the average similarity matrix between samples is available, Cluster-based Similarity Partitioning Algorithm (CSPA)…”
