WebSymmetric Learning (SL) via Symmetric Cross Entropy (SCE) loss Requirements Usage The Pytorch reimplementation Citing this work README.md Symmetric Learning (SL) via Symmetric Cross Entropy (SCE) loss Sound statistical practice requires selecting an estimator consistent with the actual acceptable variation experienced in the context of a particular applied problem. Thus, in the applied use of loss functions, selecting which statistical method to use to model an applied problem depends on knowing the losses that will be experienced from being wrong under the problem's particular circumstances.
