Smooth loss
Web8 Apr 2024 · In this post we will dig deeper into the lesser-known yet useful loss functions in PyTorch by defining the mathematical formulation, coding its algorithm and implementing in PyTorch. ... 0.5 * beta # Defining Smooth L1 Loss function (with beta defined to be 0.5) def smoothl1_loss(pred, ... Webnetworks. Consequently, we introduce a family of smoothed loss functions that are suited to top-koptimization via deep learning. The widely used cross-entropy is a special case of our family. Evaluating our smooth loss functions is computationally challenging: a na¨ıve algorithm would require O(n k) operations, where nis the number of classes.
