- W4385654380 abstract "In clustering analysis, data clusters are usually associated with feature subsets rather than the whole space. Therefore, soft subspace clustering devote to find the corresponding subspace for each cluster by assigning weight to the features. However, since categorical data is qualitative rather than quantitative data, the study of subspace clustering for categorical data is relatively rare and challenging. Therefore, this paper presents a new two-step subspace clustering algorithm for categorical data. Firstly, an initial clustering method is proposed to obtain a reliable initial cluster structure, based on which, the feature-to-cluster groups are constructed by utilizing intrinsic relationships between features. Subsequently, the local and global clustering are defined to learn the local cluster relations between data objects and achieve the final clustering results, respectively. Experimental results on benchmark datasets demonstrate the effectiveness of proposed method." @default.
