Data Mining Based on Least Squares Support Vector Machines

With the development of data warehouse and OLAP technology,data mining is becoming an impartment measure of data processing.Least Squares Support Vector Machines(LS-SVM),as a new machine learning method,has such properties as global convergence and good ability of extension.The research applies LS-SVM to data classification and prediction in terms of data mining.By kernel function selecting and parameter optimizing,the performance has been evaluated and compared with SVM,MLP neural network and discriminant analysis.
