If you are using AlexeyAB's darknet repo (not darkflow), he suggests to do Fine-Tuning instead of Transfer Learning by setting this param in cfg file : stopbackward=1. The name is an acronym for the popular motto "You only live … - Selection from Python Deep Learning - Second Edition [Book]. Training YOLOv3 : Deep Learning based Custom Object Detector. The mAP for YOLOv3-416 and YOLOv3-tiny are 55. Get the latest machine learning methods with code. I'm considering that "bounding box prior" is synonymous with "anchor". 74 CUDA version: 10. Most people are familiar with the idea that machine learning can be used to detect things like objects or people, but for anyone who's not clear on how that process actually works should check. I this article, I won't cover the technical details of YoloV3, but I'll jump straight to the implementation.
