WebOct 2, 2024 · 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 ...
