CLUSTERING WITH GRANULAR INFORMATION PROCESSING

Clustering is a part of data mining domain. Its task is to detect groups of similar objects on the basis of established similarity criterion. Granular computing (GrC) includes methods from various areas with the aim to support human with better understanding analyzed problem and generated results. Granular computing techniques create and/or process data portions named as granules identified with regard to similar description, functionality or behavior. Interesting characteristic of granular computation is offer of multi-perspective view of data depending on required resolution level. Data granules identified on different levels of resolution form a hierarchical structure expressing relations between objects of data. A method proposed in this article performs creation data granules by clustering data in form of hyperboxes. The results are compared with clustering of point-type data with regard to complexity, quality and interpretability.
