WebJan 24, 2024 · Focal Loss (FL) The loss function is reshaped to down-weight easy examples and thus focus training on hard negatives. A modulating factor (1- pt )^ γ is added to the cross entropy loss where γ is tested from [0,5] in the experiment.

WebApr 7, 2024 · Focal loss is a novel loss function that adds a modulating factor to the cross-entropy loss function with a tunable focusing parameter γ ≥ 0. The focusing parameter, γ automatically down-weights the contribution of the easy examples during training while focusing the model training on hard examples. WebOne of the best use-cases of focal loss is its usage in object detection where the imbalance between the background class and other classes is extremely high. Usage: fl = tfa.losses.SigmoidFocalCrossEntropy() loss = fl( y_true = [ [1.0], [1.0], [0.0]],y_pred = [ [0.97], [0.91], [0.03]]) loss

WebDelving more in the literature, I found that CRF is usually implemented in fully convolutional networks as an RNN, as suggested in the very nice ICCV 2015 paper from Zheng et al. They also shared an implementation here, while another implementation (that should be more flexible) has been shared here.
