Questions on bounding box predictions YOLO

You might also want to review this thread, which goes into some detail on the relationships between predicted bounding boxes dimensions, grid cells, and anchor box shapes.

Applying YOLO anchor boxes

Applying YOLO Anchor Boxes A previous thread provides an introduction to extracting from labelled ground truth data a small set, on the order of 3 <= k <= 10 , of shapes for what is referred to in the YOLO 9000 paper as dimension clusters or priors, but in this class as anchor boxes . NOTE: Just to make things more confusing, the YOLO 9000 paper uses anchor boxes to refer instead to the hand-picked shapes described in the Faster R-CNN paper, not the ones generated by K-Means. The YOLO 9000 pap…

Also, keep in mind that sometimes Prof Ng presents at a somewhat conceptual level, which may or may not translate directly to how the algorithms are implemented in the related programming exercises. In the case of YOLO, there are some nuances he understandably glosses over or simplifies for the lecture/video.
