单项式的系数

先采用基于相关性的正交前向搜索(Correlation-basedOrthogonalForwardSearch,COFS)方法确定一阶项,然后根据各单项式与输出的相关系数以及每个单项对输出的贡献度,缩小候选单项式范围。
First , choose the first order monomials by using the correlation-based orthogonal forward search algorithm . Then according to the correlation coefficient of monomial term and output and the contribution of each monomial term to system output to narrow the scope of the candidate monomials .
