Before revision:  Without additional pre-training, CBNetV2 can be integrated into mainstream detectors, including one-stage and two-stage detectors , as well as anchor-based and anchor-free-based ones, and significantly improve their performance by more than 3.0\% AP over the baseline on COCO.
After revision:  Without additional pre-training, CBNetV2 can be adapt to various backbones, including manual-based and NAS-based , as well as anchor-based and anchor-free-based ones, and significantly improve their performance by more than 3.0\% AP over the baseline on COCO.
