+3 marksOne or more correct options

Which statements are true ?

Select all that apply.

  1. A

    Smooth L1 (Huber) is often used for box regression due to robustness to outliers.

    Focal loss primarily addresses foreground/background (class) imbalance.

  3. C

    IoU loss cannot be used for box regression.

  4. D

    In two-stage detectors, the RPN has its own objectness + box regression losses.
