Abstract

Aiming at the problems of parallel support vector machine(SVM) algorithm in big data environment such as redundant data sensitivity, difficulty in parameter selection, and low parallelization efficiency, this paper proposed a parallel SVM algorithm using Relief and bacterial foraging optimization(BFO) algorithm based on MapReduce(RBFO-PSVM). Firstly, the algorithm designed a feature weight calculation strategy(MI-Relief), which used mutual information to improve the weight calculation function of Relief algorithm to eliminate redundant features in the data set and effectively reduce redundant data to support parallelism. Secondly, this paper proposed a hybrid BFO algorithm based on MapReduce(MR-HBFO), which selected the optimal parameters of SVM in parallel, and solved the problem of difficult selection of SVM parameters. Finally, it proposed the kernel clustering strategy(KCS) to reduce the size of the data set involved in parallel training, and proposed a cross-fusion cascaded parallel SVM(CFCPSVM) to improve the cascade SVM(CSVM) feedback mechanism. It trained SVM by combining with the MapReduce programming framework, and this improved the parallelization efficiency of parallel SVM. Experiments show that the RBFO-PSVM algorithm has a better classification effect on large data sets and is more suitable for large data environments.
