Cross-Entropy Loss: How Wrong Is Your Model's Guess?

Source: Wikipedia: Cross-entropyintermediate

Cross-entropy loss measures the penalty when a model's predicted probabilities diverge from the true labels. It's the standard loss for classification tasks, like telling a cat from a dog.

Cross-entropy loss measures the penalty for a model's predicted probabilities being different from the true labels. Think of it as the "surprise" your model feels when its guess is wrong. It's the default loss function for multi-class classification in neural networks, from image recognition to NLP. The common footgun is confusing it with accuracy: a model can be correct but unconfident (e.g., 51% sure it's a cat), leading to high loss despite high accuracy.
