The evolution of the YOLO neural networks family from v1 to v7.

In previous part we have considered the oldest three architectures: YOLO, YOLOv2, YOLOv3. Today we handle with the next six architectures. Joseph Redmon stepped down from further development of YOLO for ethical reasons. Comparison of the proposed YOLOv4 and other state-of-the-art object detectors. YOLOv4 runs twice faster than EfficientDet with comparable performance.
