Web5. In short, cross-entropy (CE) is the measure of how far is your predicted value from the true label. The cross here refers to calculating the entropy between two or more features / true labels (like 0, 1). And the term entropy itself refers to randomness, so large value of it means your prediction is far off from real labels.
