Abstract

Aiming at the problems of indigent scalability, poor parameter optimization ability and low efficiency of parallelization in big data density-based clustering algorithm, this paper developed a density-based clustering algorithm MR-GDBIGS based on groups and improved gravitational search. Firstly, it proposed a GSP to divide data and speed up neighborhood search. Secondly, the algorithm designed an IGSA which used the PUF. In addition, it could dynamically select the optimal parameters of local clustering based on IGSA algorithm, which could improve the clustering effect of local clustering. Finally, based on cover-tree and MapReduce, this paper developed a MR-CTMC to get the result of clustering algorithm more quickly, which improved the core clusters merging efficiency of density-based clustering algorithm. The experimental results show that the MR-GDBIGS algorithm has better clustering results and performs better parallelization in big data.
