Pytorch argmax

WebMay 20, 2024 · Since argmax () gives you the index in a flattened tensor, you can infer the position in your 2D tensor from size of the last dimension. E.g. if argmax () returns 10 and … Web1 day ago · Pytorch Mapping One Hot Tensor to max of input tensor. I have a code for mapping the following tensor to a one hot tensor: tensor ( [ 0.0917 -0.0006 0.1825 -0.2484]) --> tensor ( [0., 0., 1., 0.]). Position 2 has the max value 0.1825 and this should map as 1 to position 2 in the One Hot vector. The following code does the job.

And in dice loss, targets need to be one-hot encoded. So I chose to apply torch.argmax on targets (which is already one-hot encoded) to find cross-entropy loss. But I saw somewhere that torch.argmax is not differentiable, though I only use it on targets. china balloon blown up https://annuitech.com

WebA torch.Tensor is a multi-dimensional matrix containing elements of a single data type. Data types Torch defines 10 tensor types with CPU and GPU variants which are as follows: [ 1] Sometimes referred to as binary16: uses 1 sign, 5 exponent, and 10 significand bits. Useful when precision is important at the expense of range. [ 2] Webclass 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.
