这篇教程教大家定义一个目标函数并优化他,目标函数也可以是误差函数、成本函数或者效益函数。 1.目标函数与机器学习 我们要预先为我们的数据和参数建立一个数学方程式,然后进行优化以达到学习的效果。在优化领域,我们总是选择最小化函数;然而假如我们已经有确定函数的时候,我们反而要试着将函数最大化,而只最小化函数...

bayesopt attempts to minimize an objective function. If, instead, you want to maximize a function, set the objective function to the negative of the function you want to maximize. See Maximizing Functions. To include extra parameters in an objective function, see Parameterizing Functions. bayesopt...

At the heart of these approaches lie the scoring and objective functions that a given algorithm uses to compare competing solutions in constructing a multiple sequence alignment. These objective functions are often motivated by the biological paradigms that govern functional similarities and evolutionary ...

首先，我们定义了凸函数与凹函数。若函数对于所有参数值，在给定区间内函数值不超过连接两点的直线，则称该函数为凸函数。若函数对于所有参数值，在给定区间内函数值不小于连接两点的直线，则称该函数为凹函数。凸函数和凹函数的图形特征如图1.1所示。值得注意的是，若函数同时为凸且凹，则该函数被称为...
