And its evolution. ++A:++ (Answer from [The evolution of YOLO: Object detection algorithms Learn - Oct 12, 2021](https://blog.superannotate.com/yolo-object-detection/)) YOLO, YOLOv2, YOLOv3: Originally introduced by Joseph Redmon in Darknet, YOLO has come a long way. YOLOv4: April’s release of 2020 became the first paper not authored by Joseph Redmon. Here Alexey Bochkovski introduced novel improvements, including mind activation, improved feature aggregation, etc. References: * [Darknet - pjreddie by Joseph Redmon ](https://pjreddie.com/darknet/) * [github - pjreddie Darknet](https://github.com/pjreddie/darknet) * [github - AlexeyAB Darknet YOLOv4](https://github.com/AlexeyAB/darknet) * [github - WongKinYiu YOLOv7](https://github.com/WongKinYiu/yolov7) --- ### ++Q: YOLOv4 Darknet -++ What does yolov4.conv.137 mean in Yolov4 darknet? ++A:++ (Answer from [Stackoverflow](https://stackoverflow.com/questions/69932452/what-does-yolov4-conv-137-mean-in-yolov4-darknet#:~:text=data%20.%2Fyolov4%2Dobj.,python%20object%2Ddetection%20yolo%20yolov4)) Pre-trained YOLOv4 with weights (yolov4.conv.137) learned from MS COCO dataset was trained on 3 training datasets with....
