Our work is to show that whether good features are still critical in deep learning models. We bring two loss functions so that one works well in the classification problems and the other achieve good performance in verification problems, together to see whether they will improve the performance ...
And cls is indeed the classification loss, which is computed using Cross Entropy Loss function, as you correctly understood earlier. To confirm, Cross Entropy is currently the only classification loss function used in YOLOv8. The classification loss calculates the error for the classification task s...
In classification problems, the decision function is estimated by minimizing an empirical loss function, and then, the output label is predicted by using the estimated decision function. We propose a class of loss functions which is obtained by a deformation of the log-likelihood loss function. ...
损失函数(Loss Function )是定义在单个样本上的,算的是一个样本的误差。 代价函数(Cost Function)是定义在整个训练集上的,是所有样本误差的平均,也就是损失函数的平均。 目标函数(Object Function)定义为:最终需要优化的函数。等于经验风险+结构风险(也就是代价函数 + 正则化项)。代价函数最小化,降低经验风险...

Other loss functions used in regression models There are several other loss functions commonly used in linear regression problems. For example: the log-cosh loss which is very similar to the Huber function, but unlike the latter is twice differentiable everywhere; ...
In multi-class classification, each input x can belong to only one class (mutually exclusive classes), hence the sum probabilities of all classes should be 1: SUM(p_0,…,p_k)=1. a loss function that has the lowest value when the prediction and the ground truth are t...
