tip:老师语速超快...痛苦= = 线性分类器损失函数与最优化 \(Multiclass SVM loss: L_{i} = \sum_{j \neq y_{i}} max(0,s_{i}-s_{y_{i}}+1)\) \(Loss = \frac{1}{N} \sum_{i=1}^{N} L_{i}\) Q1: what if the sum was instead over all classes(j = yi)? A1:在计算中,我们可以知道这个没有意义,在公式中相当于加上了1,因为yi

Surrogate loss function,中文可以译为代理损失函数.当原本的loss function不便计算的时候,我们就会考虑使用surrogate loss function. 在二元分类问题中,假如我们有\(n\)个训练样本\(\{(X_1,y_1),(X_2,y_2),\cdots,(X_n,y_n)\}\),其中\(y_i\in\{0,1\}\).为了量化一个模型的好坏,我们通常使用一些损失函数,损失函数越小,模型越好.最常用的损失函数就是零一损失函数\(l(\hat y,y)
在使用Myeclipse10部署完项目后,原先不出错的项目,会有红色的叉叉,JSP页面会提示onclick函数错误 Cannot return from outside a function or method. 释义:无法从外部返回函数或方法. 如下图所示: 为此我在百度上了解后找到了下面的解决方案: 方法:window -->preferences -->myeclipse -->validation -->javascript validator for Js files 然
