WebWhile Hinge loss is the standard loss function for linear SVM, Squared hinge loss (a.k.a. L2 loss) is also popular in practice. L2-SVM is differentiable and imposes a bigger (quadratic vs. linear) loss for points which violate the margin.

Web8 May 2024 · 1st fold ran successfully but loss became nan at the 2nd epoch of the 2nd fold. The problem is 1457 train images because it gives 22 steps which leave 49 images for the last batch but there were 8 TPU cores so 8 images at a time which leave 1 image at the last. I don't know why but because of this last single image my model loss became nan.
