In view of the problem that the slow manual approval of loans and traditional classification algorithms have low recognition rate for a few sample classes, an integrated learning classification model based on PSO optimization support vector machines is proposed.Particle swarm optimization (PSO) is used to optimize the model parameters of SVM classifier.The AdaBoost integrated learning method is used to integrate SVM weak classifiers, and a loan prediction model based on multi-classifier optimization and integration is established.Taking the Lending Clud loan data set as the research object, the loan prediction model was built.The simulation results show that compared with the standard SVM algorithm and the PSO-SVM algorithm, the AdaBoost-PSO-SVM method can effectively improve the accuracy of the classification of a small number of samples, The classification accuracy of the whole sample and the generalization rate, the accuracy of the model applied to loan prediction is obviously better than other models.
