基于最小二乘支持向量机的小样本威布尔可靠性分析
Weibull Reliability Analysis in Small Samples Based on LSSVM
摘要
Abstract
Based on LSSVM,a method of improved Weibull reliability analysis was proposed. The parameters of Weibull distribution and reliability life were analyzed by the Weibull probability paper drawn by MATLAB. The analysis result comparisons were made by LSSVM, SVM and least square method. The numerical results show that the precision of the method based on LSSVM is higher than that of the least square method,and higher than that of SVM. The method based on LSSVM can improve the analysis precision and efficiency in small samples. The reliability analysis based on LSSVM is another choice of Weibull reliability analysis.关键词
