Dropout — PyTorch 2.2 documentation
https://pytorch.org/docs/stable/generated/torch.nn.Dropout.html
Web ResultDropout. During training, randomly zeroes some of the elements of the input tensor with probability p. The zeroed elements are chosen independently for each forward call and are sampled from a Bernoulli distribution. Each channel will be zeroed out independently on every forward call.

[PyTorch 学习笔记] 6.1 weight decay 和 dropout - 知乎 - 知乎专栏
https://zhuanlan.zhihu.com/p/225606205
Web ResultDropout 是另一种抑制过拟合的方法。在使用 dropout 时,数据尺度会发生变化,如果设置 dropout_prob =0.3,那么在训练时,数据尺度会变为原来的 70%;而在测试时,执行了 model.eval() 后,dropout 是关闭的,因此所有权重需要乘以 (1-dropout_prob),把数据尺度也缩放到 70%。

Tutorial: Dropout as Regularization and Bayesian Approximation
https://xuwd11.github.io/Dropout_Tutorial_in_PyTorch/
Web ResultAbstract: This tutorial aims to give readers a complete view of dropout, which includes the implementation of dropout (in PyTorch), how to use dropout and why dropout is useful. Basically, dropout can (1) reduce overfitting (so test results will be better) and (2) provide model uncertainty like Bayesian models we see in the …

[ Pytorch视频教程 ] Dropout 缓解过拟合 - pytorch中文网
https://ptorch.com/docs/4/pytorch-video-dropout/
Web Result我们在这里搭建两个神经网络, 一个没有 dropout, 一个有 dropout. 没有 dropout 的容易出现 过拟合, 那我们就命名为 net_overfitting, 另一个就是 net_dropped. torch.nn.Dropout(0.5) 这里的 0.5 指的是随机有 50% 的神经元会被关闭/丢弃.
