WebApr 17, 2024 · Hinge Loss. 1. Binary Cross-Entropy Loss / Log Loss. This is the most common loss function used in classification problems. The cross-entropy loss decreases as the predicted probability converges to the actual label. It measures the performance of a classification model whose predicted output is a probability value between 0 and 1. WebThis is used for measuring the error of a reconstruction in for example an auto-encoder. Note that the targets y y should be numbers between 0 and 1.
