the dot products grow large in magnitude, pushing the softmax function into regions where it has extremely small gradients . To counteract this effect, we scale the dot products by

sigmoid function. 图像 该图显示了softmax函数的基本属性,值越大,其概率越高。 Sigmoid函数与Softmax函数之间的差异 以下是Sigmoid和Softmax函数之间的差异表格: 结论 在本文中,详细了解确定逻辑回归模型的两个函数。 Softmax:用于多分类任务。 Sigmoid:用于二进制分类任务。 From: https://yq.aliyun.com 三 逻辑...
The *softmax function*, invented in 1959 by the social scientist R Duncan Luce in the context of *choice models* does precisely this. To transform our logits such that they become nonnegative and sum to $1$, while requiring that the model remains differentiable, we first exponentiate each...
