WebMar 22, 2024 · But there was a problem while using IoU as the loss function: if two non-overlapping objects were found, then the gradient of the loss would be zero and it couldn't be further optimized. Hence Generalized Intersection over Union was introduced which takes care of the non-overlapping objects by setting the metric to be a negative value.
