Softmax Function and Cross Entropy Loss Function

https://guandi1995.github.io/Softmax-Function-and-Cross-Entropy-Loss-Function/

Hence, it leads us to the cross-entropy loss function for softmax function. Cross-entropy loss function for softmax function. The mapping function \(f:f(x_i;W)=Wx_i\) stays unchanged, but we now interpret these scores as the unnormalized log probabilities for each class and we could replace the hinge loss/SVM loss with a cross-entropy loss that has the form:
