Machine Learning|番外篇-1 交叉熵代价函数(Cost Function) 从二次损失函数开始 sigmoid的函数及导数特性 使用二次损失函数的逻辑回归将‘学习缓慢’ 引入交叉熵cross-entropy 交叉熵的定义 逻辑回归是怎么勾搭上交叉熵的? 民谣与辟谣 从二次损失函数开始 回想线性回归的损失函数,使用的是二次损失函数quadratic loss ...
损失函数(Loss/Error Function): 计算单个训练集的误差,例如:欧氏距离,交叉熵,对比损失,合页损失 代价函数(Cost Function): 计算整个训练集所有损失之和的平均值 至于目标函数(Objective function),字面一些,就是有某个(最优化)目标的函数,比如最优化这个目的。没有找到定义,个人理解,目标函数是一个大类,包含损失函...

An objective function model is proposed for cost in optimizing and allocating tolerance with consideration of manufacturing conditions. With the fuzzy comprehensive evaluation method,a manufacturing difficulty coefficient is derived,which takes into account of several factors affecting the manufacturing cost,...
Quantum computers provide a valuable resource to solve computational problems. The maximization of the objective function of a computational problem is a crucial problem in gate-model quantum computers. The objective function estimation is a high-cost pr
类似于linear regression,K-means算法也optimization objective或者是试图使cost function求最小值。 了解K-means算法的optimization objective有助于我们(1)调试算法时,看算法是否运行正确(在本节中可以看到)(2)使算法找到更好的cluster,避免局部最优解(在下节中会讲) ...
