WebDec 1, 2024 · Cross-Entropy Loss: Also known as Negative Log Likelihood. It is the commonly used loss function for classification. Cross-entropy loss progress as the predicted probability diverges from the actual label. Python3 def cross_entropy (y, y_pred): return - np.sum(y * np.log (y_pred) + (1 - y) * np.log (1 - y_pred)) / np.size (y) Output (5) WebFeb 27, 2024 · Binary cross-entropy, also known as log loss, is a loss function that measures the difference between the predicted probabilities and the true labels in binary classification problems. It …
