WebMar 3, 2024 · We apply a combination of dice loss and binary cross entropy (BCE) to train model. We chose to use conventional BCE for binary classification and Dice, which is commonly used for semantic segmentation. Dice is equivalent to examining from the global level, which can solve the problem of unbalanced samples well. However, disadvantage … WebCustom Loss Functions and Metrics - We'll implement a custom loss function using binary cross entropy and dice loss. We'll also implement dice coefficient (which is used for our loss) and mean intersection over union , that will help us monitor our training process and judge how well we are performing.
