Dec 15, 2020 · The first step when designing a PyTorch neural network class for multi-class classification is to determine its architecture. Neural architecture includes the number of input and output nodes, the number of hidden layers and the number of nodes in each hidden layer, the activation functions for the hidden and output layers, and the initialization algorithms for the hidden and output layer nodes.

Nov 04, 2020 · With PyTorch, to do multi-class classification, you encode the class labels using ordinal encoding (0, 1, 2, . .) and you don’t explicitly apply any output activation, and you use the highly specialized (and completely misnamed) CrossEntropyLoss() function. When I was first learning how to use PyTorch, this new scheme baffled me.
