![]() Loss Function: It uses Binary cross-entropy with logits loss.ĭifferent Types of YOLOv5 YOLOv5 Model Comparison.Activation and Optimization: YOLOv5 uses leaky ReLU and sigmoid activation, and SGD and ADAM as optimizer options.YOLOv5 Head: Layers that generate predictions from the anchor boxes for object detection.Īpart from this YOLOv5 uses the below choices for training –.YOLOv5 Neck: It uses PANet to generate a feature pyramids network to perform aggregation on the features and pass it to Head for prediction.YOLOv5 Backbone: It employs CSPDarknet as the backbone for feature extraction from images consisting of cross-stage partial networks.The YOLO family of models consists of three main architectural blocks i) Backbone, ii) Neck and iii) Head. (As we will see in the examples of this tutorial) YOLOv5 Architecture ( Source) Probably if you are just a developer, you would not even care about the controversy and may enjoy working with YOLOv5 due to its ease of use. iii) Is YOLOv5 Good or Bad?Ĭertainly, the controversy behind YOLOv5 is just due to its choice of name, but it does not take away the fact that this is after all a great YOLO object detection model ported on PyTorch. Instead, it is considered as the PyTorch extension of YOLOv3 and a marketing strategy by Ultranytics to ride on the popularity of the YOLO family of object detection models.īut one should note that when YOLOv3 was created, Glenn Jocher (creator of YOLOv5) contributed to it by providing the implementation of mosaic data augmentation and genetic algorithm. Neither it is seen to have implemented any novel techniques to claim itself as the next version of YOLO. ![]() YOLOv5 is controversial due to the fact that no paper has been published yet (till the time of writing this) by its author Glenn Jocher for the community to peer review its benchmark. Finally, we will show you how to use YOLOv5 for object detection on various images and videos. We will understand what is YOLOv5 and do a high-level comparison between YOLOv4 vs YOLOv5. In this article, we will go through the tutorial of YOLOv5 for object detection which is supposed to be the latest model of the YOLO family. ![]()
