Let’s take a simple example, where we have three classes. Softmax and Cross Entropy with Python implementation | HOME Cross Entropy Because log(0) is negative infinity, when your model trained enough the output distribution will be very skewed, for instance say I'm doing a 4 class output, in the beginning my probability looks like. the “true” label from training samples, and q (x) depicts the estimation of the ML algorithm. Caffe: SoftmaxWithLoss Layer. derivative The Softmax Function. Softmax Classifiers Explained Neural networks produce multiple outputs in multiclass classification problems.
