WebLabel Smoothing is already implemented in Tensorflow within the cross-entropy loss functions. BinaryCrossentropy, CategoricalCrossentropy. But currently, there is no official implementation of Label Smoothing in PyTorch. However, there is going an active discussion on it and hopefully, it will be provided with an official package. WebIt is very simple to implement the label smoothing cross entropy loss function in PyTorch. In this example, we use part of the code from the fast.ai course.
