ConfidencePenaltyLoss#

class torch_uncertainty.losses.ConfidencePenaltyLoss(reg_weight=1, reduction='mean', eps=1e-06)[source]#

The Confidence Penalty Loss.

Parameters:

  • reg_weight (float, optional) – The weight of the regularization term.

  • reduction (str, optional) – specifies the reduction to apply to the output:'none' | 'mean' | 'sum'. Defaults to “mean”.

  • eps (float, optional) – A small value to avoid numerical instability. Defaults to 1e-6.
