softmax函数用于将任意实数向量转换为概率值,确保结果之和为1且位于0-1之间。分类交叉熵损失衡量预测概率与实际标签间的差异,专用于多类分类任务。在多类分类问题中,每个样本只属于一个类。交叉熵接受两个离散概率分布作为输入,输出表示两个分布相似度的数值。该损失函数在多类分类任务中,利用softmax...
The cross-entropy (CE) method is one of the most significant developments in stochastic optimization and simulation in recent years. This book explains in detail how and why the CE method works. The CE method involves an iterative procedure where each iteration can be broken down into two phase...
CrossEntropy 交叉熵推导 1. 引言 我们都知道损失函数有很多种:均方误差(MSE)、SVM的合页损失(hinge loss)、交叉熵(cross entropy)。这几天看论文的时候产生了疑问:为啥损失函数很多用的都是交叉熵(cross entropy)?其背后深层的含义是什么?如果换做均方误差(MSE)会怎么样?下面我们一步步来揭开交叉熵的神秘面纱。
In short, cross-entropy is exactly the same as the negative log likelihood (these were two concepts that were originally developed independently in the field of computer science and statistics, and they are motivated differently, but it turns out that they compute excactly the same in our classi...
