By taking optimization for culture media of diamondback moth as example,theoretical research of SVR model in media optimization was carried out.Based on initial composition,Secondary Leave-one-out was carried out after kernel optimization and descriptors screening,the precision is higher than linear regression model,it is showed that SVR is proper for media optimization.

本文首先以文献报道的小菜蛾饲料配方优化数据为例,建立基于SVR优化配方、分析因子效应的方法学:从原始配方样本集出发,以SVR进行核函数寻优和自变量筛选后实施双重留一法预测,预测精度优于多元线性回归模型,表明非线性的SVR更适合用于优化配方。
