Web13 nov. 2024 · Further, we propose a novel gradient harmonizing mechanism (GHM) to be a hedging for the disharmonies. The philosophy behind GHM can be easily embedded into both classification loss function like cross-entropy (CE) and regression loss function like smooth-L_1 (SL_1) loss. To this end, two novel loss functions called GHM-C and … Web9 mrt. 2024 · IoU loss only works when the predicted bounding boxes overlap with the ground truth box. IOU loss would not provide any moving gradient for non-overlapping …
