WebHuberLoss(reduction='mean', delta=1.0)[source]¶ Creates a criterion that uses a squared term if the absolute element-wise error falls below delta and a delta-scaled L1 term otherwise. This loss combines advantages of both L1Lossand MSELoss; the delta-scaled L1 region makes the loss less sensitive to outliers than MSELoss, Web《动手学深度学习（PyTorch版）》的学习笔记（2）
