I’ve identified four steps that need to be taken in order to successfully implement a custom loss function for LightGBM: The focal loss is described in “Focal Loss for Dense Object Detection” and is simply a modified version of binary cross entropy in which the loss for confidently correctly classified labels is scaled down, so that the Focal Loss (an Extension to Cross Entropy loss): Basically Focal loss is an extension to cross entropy loss. In focal loss, there’s a modulating factor multiplied to the Cross-Entropy loss.
