WebEngineering AI and Machine Learning 2. (36 pts.) The “focal loss” is a variant of the binary cross entropy loss that addresses the issue of class imbalance by down-weighting the contribution of easy examples enabling learning of harder examples Recall that the binary cross entropy loss has the following form: = - log(p) -log(1-p) if y otherwise.
