article = "<p style='text-align: center'>YOLOv5 is a family of compound-scaled object detection models trained on the COCO dataset. We performed fine-tuning of models trained by Ultralytics with the help of their awesome <a href='https://github.com/ultralytics/yolov5'>code repository</a>. The data comes from a community challenge organized by [Kili](https://kili-technology.com/blog/kili-s-community-challenge-plastic-in-river-dataset), and the demo site is heavily inspired from the original [YoloV5 space](https://huggingface.co/spaces/akhaliq/YOLOv5). We will update the model during the challenge."
