Spatial Clustering with Obstacles Constraints by dynamic piecewise-mapped and nonlinear inertia weights PSO

Abstract

Spatial clustering with constraints has been a new topic in spatial data mining. A novel Spatial Clustering with Obstacles Constraints (SCOC) by dynamic piecewise-mapped and nonlinear inertia weights particle swarm optimization is proposed in this paper. The experiments show that the algorithm can not only give attention to higher local constringency speed and stronger global optimum search, but also get down to the obstacles constraints and practicalities of spatial clustering; and it performs better than PSO K-Medoids SCOC in terms of quantization error and has higher constringency speed than Genetic KMedoids SCOC. © 2010 Springer-Verlag Berlin Heidelberg.
