I try to understand the architecture of Yolo4. It is composed of a backbone, neck, dense prediction and sparse prediction. Knowing that Yolo 3 has already a backbone, Is Yolo 4 taking all the architecture of Yolo 3 including its backbone or just part of Yolo3 ?
In page number 5 in paper Yolo 4, they've mentioned anchor based for Yolo3
Yolo 4 : https://arxiv.org/pdf/2004.10934.pdf
