Hierarchical Information-Theoretic Co-Clustering for high dimensional data

Abstract

Hierarchical clustering is an important technique for hierarchical data exploration applications. However, most existing hierarchial methods are based on traditional one-side clustering, which is not effective for handling high dimensional data. In this paper, we develop a partitional hierarchical co-clustering framework and propose a Hierarchical Information-Theoretical Co-Clustering (HITCC) algorithm. The algorithm conducts a series of binary partitions of objects on a data set via the Information- Theoretical Co-Clustering (ITCC) procedure, and generates a hierarchical management of object clusters. Due to simultaneously clustering of features and objects in the process of building a cluster tree, the HITCC algorithm can identify subspace clusters at different-level abstractions and acquire good clustering hierarchies. Compared with the flat ITCC algorithm and six state-of-the-art hierarchical clustering algorithms on various data sets, the new algorithm demonstrated much better performance.
