WebIn the end one could just use "categorical cross entropy", as this is how it is mathematically defined, however since things like hard targets or binary classification are very popular - modern ML libraries do provide these additional helper functions to make things simpler. In particular "stacking" sigmoid and cross entropy might be numerically unstable, but if one … Web2 days ago · To train the model I'm using the gradient optmizer SGD, with 0.01. We will use the accuracy metric to track the model, and to calculate the loss, cost function, we will use the categorical cross entropy (categorical_crossentropy), which is the most widely employed in classification problems.

Web15 Jul 2024 · Categorical cross entropy loss function, where x is the predicted probability of the ground truth class Notice that the loss is exactly 0 if the probability of the ground truth class is 1 as desired. Also, as the probability of the ground truth class tends to 0, the loss tends to positive infinity as well, hence substantially penalizing bad predictions.
