Object Detection as a Positive-Unlabeled Problem

no code implementations11 Feb 2020 Yuewei Yang, Kevin J Liang, Lawrence Carin

These missing annotations can be problematic, as the standard cross-entropy loss employed to train object detection models treats classification as a positive-negative (PN) problem: unlabeled regions are implicitly assumed to be background.
