pytorch.org › generated › torchSoftmax — PyTorch 1.10.0 documentation Softmax class torch.nn.Softmax(dim=None) [source] Applies the Softmax function to an n-dimensional input Tensor rescaling them so that the elements of the n-dimensional output Tensor lie in the range [0,1] and sum to 1. Softmax is defined as:
torch.nn.functional.softmax — PyTorch 1.10.1 documentation
pytorch.org › torchApplies a softmax function. Softmax is defined as: \text {Softmax} (x_ {i}) = \frac {\exp (x_i)} {\sum_j \exp (x_j)} Softmax(xi ) = ∑j exp(xj )exp(xi ) It is applied to all slices along dim, and will re-scale them so that the elements lie in the range [0, 1] and sum to 1. See Softmax for more details. Parameters input ( Tensor) – input
The PyTorch Softmax Function - Sparrow Computing
https://sparrow.dev/pytorch-softmax29.01.2021 · The easiest way to use this activation function in PyTorch is to call the top-level torch.softmax () function. Here’s an example: import torch x = torch.randn (2, 3, 4) y = torch.softmax (x, dim=-1) The dim argument is required unless your input tensor is a vector. It specifies the axis along which to apply the softmax activation.
