Interesting this is trending now. We have actually just recently released an improved version of YoloV3 (called G-Darknet) https://github.com/generalized-iou/g-darknet https://github.com/generalized-iou/g-darknet, using GIoU as a loss, which is described here: https://giou.stanford.edu https://giou.stanford.edu
Also notable in G-Darknet are some tools useful for training (called darkboard), see https://github.com/generalized-iou/g-darknet/tree/master/darkboard#setup https://github.com/generalized-iou/g-darknet/tree/master/dar...

- natvert 8y agoThx, I'll check that
- elephantum 8y agoInteresting idea! Though I have a question: in order to calculate C you need a way to attribute proposal and ground truth. It's trivial in case when there's only one instance of each class in the image. But how does it work, when you're working with a set of same-class object? For example detecting each car in traffic.
- natvert 8y agoGood question, we use the same method as coco, described in https://arxiv.org/pdf/1405.0312.pdf https://arxiv.org/pdf/1405.0312.pdf and implemented in the coco evaluation scripts here: https://github.com/cocodataset/cocoapi/blob/master/PythonAPI/pycocotools/cocoeval.py#L278 https://github.com/cocodataset/cocoapi/blob/master/PythonAPI... -- basically the best matching proposal, ground truth pair
