Categorical crossentropy is a loss function that is used in multi-class classification tasks. These are tasks where an example can only belong to one out of many possible categories, and the model must decide which one. Formally, it is designed to quantify the difference between two probability distributions. Categorical crossentropy math.

Oct 21, 2020 · This patterns is the same for every classification problem that uses categorical cross entropy, no matter if the number of output classes is 10, 100, or 100,000. Voila! Also important to note that, the keras api is using auto to reduce the losses, which essentially averages the cross entropy for each training batch.
