Attribute Value Weighting in K-Modes Clustering
Zengyou He, Xaiofei Xu, Shengchun Deng
In this paper, the traditional k-modes clustering algorithm is extended by weighting attribute value matches in dissimilarity computation. The use of attribute value weighting tech…
Approximation Algorithms for K-Modes Clustering
Zengyou He
In this paper, we study clustering with respect to the k-modes objective function, a natural formulation of clustering for categorical data. One of the main contributions of this p…
