Before revision:   Without additional pre-training, CBNetV2 can be adapt to various backbones, including manual-based and NAS-based, as well as CNN-based and Transformer-based ones.
After revision:  CBNetV2 has strong generalization capabilities for different backbones and head designs of the detector architecture. Without additional pre-training, CBNetV2 can be adapt to various backbones, including manual-based and NAS-based, as well as CNN-based and Transformer-based ones.
