摘要:
在模式识别领域 ,基于Fisher鉴别准则函数的Sammon最佳鉴别平面技术有着重大的影响。特征抽取的一般原则是最好抽取模式的不相关的特征 ,而Sam mon最佳鉴别平面的 2个鉴别投影方向虽然是正交的 ,但一般也是统计相关的。金忠等[1] 提出了一种统计不相关的最佳鉴别平面 ,但其 2个鉴别投影方向却一般不是正交的。文中从Fisher鉴别准则函数出发 ,提出了一种改进的最佳鉴别平面 ,并在最后给出了改进的最佳鉴别矢量集的求解方法。实验结果表明 ,改进的最佳鉴别平面具有良好的分类效果
Abstract:
Somet imes the result is not sat isf ied when static systems have been designed w ith Stat ic T aguchi Methods. T he general resolution is to re-select factors or responses and redo experiment s. But this method seems not ef fective and will lead to the increase of experimental cost . According to dynamic theory, this paper has proposed a new effect ive method. Namely, those stat ic systems can be designed successfully w ith Dynamic T aguchi Methods by convert ing static characterist ic to dynamic characterist ic. In this paper, as an example, guidelines of plastic design parameters have been designed w ith this method and a satisfied result has been obtained. In this w ay, no ext ra experiment s are needed because the original experimental data can be reused.
