Optim.sgd weight_decay
Web文章目录前馈神经网络实验要求一、利用torch.nn实现前馈神经网络二、对比三种不同的激活函数的实验结果前馈神经网络前馈神经网络，又称作深度前馈网络、多层感知机，信息流经过中间的函数计算， 最终达到输出，被称为“前向”。模型的输出与模型本身没有反馈连接。 WebWeight decay is a regularization technique by adding a small penalty, usually the L2 norm of the weights (all the weights of the model), to the loss function. ... we can simply define the weight decay parameter in the torch.optim.SGD optimizer or the torch.optim.Adam optimizer. Here we use 1e-4 as a default for weight_decay. optimizer = torch ...

Webweight_decay ( float, optional) – weight decay (L2 penalty) (default: 0) foreach ( bool, optional) – whether foreach implementation of optimizer is used. If unspecified by the user (so foreach is None), we will try to use foreach over the for-loop implementation on CUDA, since it is usually significantly more performant. (default: None) Webp_ {t+1} & = p_ {t} - v_ {t+1}. The Nesterov version is analogously modified. gradient value at the first step.
