在PyTorch中,可以使用torch.nn中的模块来实现各种激活函数。以下是几种常见的激活函数的示例代码:
ReLU激活函数:import torchimport torch.nn as nninput = torch.randn(1, 10)relu = nn.ReLU()output = relu(input)Sigmoid激活函数:import torchimport torch.nn as nninput = torch.randn(1, 10)sigmoid = nn.Sigmoid()output = sigmoid(input)Tanh激活函数:import torchimport torch.nn as nninput = torch.randn(1, 10)tanh = nn.Tanh()output = tanh(input)Softmax激活函数:import torchimport torch.nn as nninput = torch.randn(1, 10)softmax = nn.Softmax(dim=1)output = softmax(input)使用这些代码,可以很方便地在PyTorch中实现各种激活函数。
