think it's going to be a soft Max or a sorry a cross-entropy loss like in usual classification and the loss on the to say whether to bounding boxes agree is a mixture of the l1 loss that compares to bounding boxes and this iou loss which is not dependent on the scale of the bounding boxes it kind of computes how much fraction of the two bounding boxes overlap but in any case the lost base they consist of saying how eyeli how much do the labels agree and how much do the bounding boxes agree okay again this is only possible because after that you
