Web8 de set. de 2024 · The training step takes images and labels in batches. we use cross-entropy for loss function and calculate the loss and return the loss. This is similar to the validation step as we can see in the function. The epoch ends combine losses and accuracies and finally, we print the accuracies and losses. Here We will bring some available best implementation of Label Smoothing (LS) from PyTorch practitioner. Basically, there are many ways to implement the LS. Please refer to this specific discussion on this, one is here, and another here. Here we will bring implementation in 2 unique ways with two versions of each; so total 4.
