A K-medoids Clustering Algorithm with Initial Centers Optimized by a P System
In this paper an improved K-medoids algorithm by a specific P system is proposed which extends the application of membrane computing.The traditional K-medoids clustering results vary accordingly to the initial centers which are selected randomly.In order to conquer the defect,we improve the algorithm by selecting the k initial centers based on the density parameter of data points.P system is adequate to solve clustering problem for its high parallelism and lower computational time complexity.A specific P system with the aim of realizing the improved K-medoids algorithm to form clusters is constructed.By computation of the designed system,it obtains one possible clustering result in a non-deterministic and maximal parallel way.Through example verification,it can improve the quality of clustering.
