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 function。 损失函数(cost function): J(θ0,&the... ...
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...
Objective Function Example This objective function returns the loss in a cross-validated fit of an SVM model with parametersboxandsigma. The objective also returns a coupled constraint function that is positive (infeasible) when the number of support vectors exceeds 100 (100 is feasible, 101 is ...
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
sampling in-progress molecules and minimizing a multi-objective loss function. The loss function contains both the difference between the predicted value score and the final rollout reward and the difference between predicted prior probabilities and the actual search probabilities for each of the molecule...
Existing supervised learning models are generally built upon the basis of only one single objective function, through the minimizing of the square-loss (neural networks) or the minimizing of the information entropy (decision tree). Due to the inherent complexity of the real-life data, learning mod...

Specifically, this work proved that the alternative optimization strategy (AOS) on SPL accords with a majorization minimization (MM) algorithm implemented on an implicit objective function. Furthermore, it is found that the loss function contained in this implicit objective has a similar configuration ...
