摘要
Abstract
The prediction problem is the core of large data.The existing BP_Adaboost algorithm is a fusion in BP neural network model of prediction model algorithm.As the accuracy of BP_Adaboost algorithm is not high, the BP_Adaboost algorithm is improved in our stndy.BP neural network model is put as a weak predictor,and the strong predictor of multiple BP neural network composed of weak predictor is obtained by BP_Adaboost algo-rithm.Genetic algorithm is used for each BP neural network prediction model for optimization.When optimized BP neural network model as a new weak predictor,and through the BP_Adaboost algorithm,the BP neural net-work by genetic algorithm optimization of weak predictor is composed of strong predictor model.From 2 000 groups of random experimental data,the prediction accuracy to verify the improved algorithm leads to improved BP_Adaboost algorithm simulation with Matlab program.The result is compared with the BP_Adaboost algo-rithm before improvement.From the result of running program,the prediction of the improved BP_Adaboost al-gorithm possesses higher precision.关键词
