@yangxu351 inverse frequency weights.
@glenn-jocher Thanks for your quick reply. But I feel a little confusing, the xview class weights are obtained according to the inverse frequency of each class, are the xview_class_weights_hard_mining also obtained according to the inverse frequency weights? What's the difference? Or anything I wrongly understood?
@yangxu351 this may refer to image or chip weighting, which deals with how often to present a given image or chip for learning. What you are showing above are the class weights, which are inverse frequencies.
@yangxu351 in any case, I do not recommend using this repo, as https://github.com/ultralytics/yolov3 is much better performing and currently maintained. You can train COCO from scratch to 61.4 mAP for example on it, better than darknet.
@glenn-jocher Thanks.

@yangxu351 you're welcome! If you have further questions, feel free to ask.
Hello, I know this repo is not under active, but I want to reproduce the repo on xview, could you please explain how did you get the hard mining class weight in utils/utils.py?
