Activation: 就是引入非线性,让神经网络可以描述更加复杂的问题 Torch 中的激励函数有很多, 不过我们平时要用到的就这几个. relu, sigmoid, tanh, softplus import torch import torch.nn.functional as F from torch.autograd import ...
仿射函数的仿射函数本⾝就是仿射函数,但是我们之前的线性模型已经能够表⽰任何仿射函数。 为了发挥多层架构的潜⼒,我们还需要⼀个额外的关键要素:在仿射变换之后对每个隐藏单元应⽤⾮线性的激活函数(activation function)σ激活函数的输出(例如,σ(·))被称为活性值(activations),有了激活函数,就不可能再将...

第一讲中,我将深度学习代码拆解成七步。到前一讲为止,这七步已经讲解完了。但这还远远不够,现在深度学习是大模型为王的时代,都是多张卡训练,有时候甚至需要集群训练模型。并且,训练过程涉及超参数优化。因此…
nn.ParameterList&nn.ParameterDict 这个类实际上是将一个Parameter的List转为ParameterList,如下例所示[nn.Parameter(torch.randn(10, 10)) for i in range(10)]类型是List,List的每个元素是Parameter,然后这个List作为参数传入这个类构造ParameterList类型。ParameterList输入一定是一个Parameter的List,其他类型会报错,...
