now the client needs to obtain a square of a function interface (target), pass a number, get it squared value.
现在客户端需要一个求得一个数的平方的函数接口(target),传入一个数,得到它的平方值。
Its main modeling process is that: first, establishes a second or a polynomial fitting function through the fixed dimensions of new discrete sequence; second, determines the associated threshold by the squared residuals minimum standards; the third, Screens function by the residual value calculation.
其主要的建模过程是:通过固定维度的新离散数列,建立二次或高次多项式等拟合函数;以残差平方和最小准则确定关联阈值;通过残差绝对值计算筛选函数。
