Abstract:It programs the model on MapReduce model.In the classification stage,KNN based on MapReduce is designed and used,and the classification experiment is performed on Fudan dataset.The result shows that parallel particle swarm optimization for projection pursuit based on MapReduce has both well effectiveness and higher efficiency than its serial counterpart.
Keywords:projection pursuit  PSO  MapReduce  text classification  parallel
