Binary cross-entropy loss function
WebOur solution is that BCELoss clamps its log function outputs to be greater than or equal to -100. This way, we can always have a finite loss value and a linear backward method. … WebThen, to minimize the triplet ordinal cross entropy loss, it should be a larger probability to assign x i and x j as similar binary codes. Without the triplet ordinal cross entropy loss, …

WebBatch normalization [55] is used through all models. Binary cross-entropy serves as the loss function. The networks are trained with four GTX 1080Ti GPUs using data parallelism. Hyperparameters are tuned on the validation set. Data augmentation is implemented to further improve generalization. WebCross-Entropy ¶ Cross-entropy loss, or log loss, measures the performance of a classification model whose output is a probability value between 0 and 1. Cross-entropy loss increases as the predicted …
