AbstractIoULoss

class hybrid_learning.concepts.train_eval.kpis.batch_kpis.AbstractIoULoss(reduction=BatchReduction.mean, target_thresh=0.0)[source]

Bases: AbstractIoULike

Shared settings for intersection over union based losses. The difference to IoU based metrics is that only the targets are binarized, not the outputs. Thus, the function on the DNN outputs stays smoothly differentiable.

Public Data Attributes:

settings

Settings dict to reproduce instance.
Inherited from : py: class:Module

dump_patches

This allows better BC support for load_state_dict().

T_destination

alias of TypeVar('T_destination', bound=Mapping[str, Tensor])
