When considering the problem of classifying an input to one of 2 classes, 99% of the examples I saw used a NN with a single output and sigmoid as their activation followed by a binary cross-entropy loss. Another option that I thought of is having the last layer produce 2 outputs and use a categorical cross-entropy ...

26.02.2021 · Both categorical cross entropy and sparse categorical cross-entropy have the same loss function as defined in Equation 2. The only difference between the two is on how truth labels are defined. Categorical cross-entropy is used when true labels are one-hot encoded, for example, we have the following true values for 3-class classification problem [1,0,0] , [0,1,0] and …
May 23, 2018 · TensorFlow: softmax_cross_entropy. Is limited to multi-class classification. In this Facebook work they claim that, despite being counter-intuitive, Categorical Cross-Entropy loss, or Softmax loss worked better than Binary Cross-Entropy loss in their multi-label classification problem.
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 ...

Binary cross entropy is just a special case of categorical cross entropy. The equation for binary cross entropy loss is the exact equation for categorical cross entropy loss with one output node. For example, binary cross entropy with one output node is the equivalent of categorical cross entropy with two output nodes. 5 level 1 bhatt_gaurav · 3y
With binary cross entropy, you can only classify two classes. With categorical cross entropy, you're not limited to how many classes your model can classify. Binary cross entropy is just a special case of categorical cross entropy. The equation for binary cross entropy loss is the exact equation for categorical cross entropy loss with one output node.
