Characterizations of best simultaneous approximation from sets of generalized polynomials with restricted coefficients 具限制系數(shù)廣義多項式集的最佳同時逼近特征
Result shows that kriging method and rbf method are two useful approximation approaches , especially for high dimension problem . in addition , this article created a generalized polynomial response surface model , and result shows that it can be also used to describe the lift distribution 同時計算結(jié)果還顯示, kriging模型和徑向基函數(shù)模型作為兩種通用模型,可以很好的解決一般的高維非線性代理模型的構(gòu)造問題;另外,從算例問題的物理本質(zhì)出發(fā)所構(gòu)造的廣義多項式響應面模型也能夠滿足精度要求。
