Hypersphere Neighborhood Rough Set for Rapid Attribute Reduction at least .. In this paper, we propose a hypersphere neighborhood rough set (HNRS) algorithm with a time complexity of .(.). HNRS adaptively generates the neighborhood radius without manual setting. First, a set of hyperspheres is built to accurately describe the decision boundary on the original da

A Novel Clustering Algorithm with Dynamic Boundary Extraction Strategy Based on Local Gravitationhods have received increasing attention. However, discovering arbitrarily shaped clusters, determining the location and number of clustering cores and dealing with fuzzy boundaries is tough for most algorithms. We propose a novel clustering algorithm with dynamic boundary extraction strategy based o
