WebAug 21, 2024 · The IOU loss has achieved better IOU than the l n-norm loss [12]. However, if there is no overlap between bounding boxes, it would stop working and no longer contribute to the gradient. To alleviate this problem, Rezatofighi et al. [13] proposed the Generalized IOU (GIOU) loss (in Eq. (5)). WebJun 7, 2024 · "I lost nearly $120,000 there," he said. His vadai business was also affected in 2024.
