SmoothL1Loss class
keras_cv.losses.SmoothL1Loss(l1_cutoff=1.0, **kwargs)
Implements Smooth L1 loss.
SmoothL1Loss implements the SmoothL1 function, where values less than
l1_cutoff contribute to the overall loss based on their squared
difference, and values greater than l1_cutoff contribute based on their raw
difference.
Arguments
- l1_cutoff: differences between y_true and y_pred that are larger than
l1_cutoffare treated asL1values
