Research of stock yield has high reference value for stock investors. Aiming at the exiting parameters selection difficulties of support vector machines(SVM) and poor classification performance problems
an improved Boruta-particle swarm optimization(PSO)-SVM algorithm is put forward based on feature selection and PSO.Feature selection for training set to reduce input dimensions through Boruta algorithm. PSO is used to optimize the kernel function parameters of SVM
so as to improve the classification performance of SVM. Experimental results show that compare with decision tree
neural network
extreme learning machine algorithm
the new algorithm has higher classification precision
it can improve performance of classification prediction of stock yield.
