Pretreatment method of data mining based on non-linear correlation analysis
一种新的数据预处理算法——NLCA

An estimation model for credit risk and the optimal portfolio in the commercial bank has become an extremely important subject to business dealing.A novel pretreatment method of Non-linear Correlation Analysis(NLCA) was presented in the data mining of credit risk evaluation and the optimal portfolio,and the aggregation character of the conjunction graph was studied,then the convergence and validity of the arithmetic of NLCA was put out,at last applying it to the real data.
