( 2 ) the performance of support vector machine ( svm ) for classification was analyzed . it was found that svm for classification is more sensitive to noise than other methods , in particular , the kernel function , its parameter and penalty factor c are the main factor affecting the classification performance of svm ( 2 )支持向量机采用了结构风险最小化( srm )原则,用于模式分类已表现出优良的性能,但在观测数据中存在复共线性时,其分类效果就有所降低。
Correlative component analysis ( cca ) was used to eliminate multicollinearity and noise of original sample data before classifying by svm . to improve the classification performance of svm and obtain the optimal discriminative function , the ega proposed in this work was used to optimize the parameters of svm including correlative components ( ccs ) , penalty factor c , and kernel width factor 因此,为了充分利用支持向量机良好的分类能力,使之能处理存在复杂相关关系的观测数据,给出了结合分类相关成分分析( cca )的支持向量机建立分类模型的方法( cca - svm ) ,又利用本文第三章所提出的ega算法优化分类相关成分数及支持向量机参数。
