WebAs all the other losses in PyTorch, this function expects the first argument, input, to be the output of the model (e.g. the neural network) and the second, target, to be the observations in the dataset. This differs from the standard mathematical notation KL (P\ \ Q) K L(P ∣∣ Q) where P P denotes the distribution of the observations and ... Webconv_transpose3d. Applies a 3D transposed convolution operator over an input image composed of several input planes, sometimes also called "deconvolution". unfold. Extracts sliding local blocks from a batched input tensor. fold. Combines an array of sliding local blocks into a large containing tensor.
