A Comprehensive Overhaul of Distilling Unconditional GANs

no code implementations29 Sep 2021 Guodong Xu, Yuenan Hou, Ziwei Liu, Chen Change Loy

To further enhance the semantic consistency between the teacher and student model, we present another latent-direction-based distillation loss that preserves the semantic relations in latent space.

Towards Evaluating and Training Verifiably Robust Neural Networks

1 code implementation CVPR 2021 Zhaoyang Lyu, Minghao Guo, Tong Wu, Guodong Xu, Kehuan Zhang, Dahua Lin

Recent works have shown that interval bound propagation (IBP) can be used to train verifiably robust neural networks.

X-view: Non-egocentric Multi-View 3D Object Detector

no code implementations24 Mar 2021 Liang Xie, Guodong Xu, Deng Cai, Xiaofei He

3D object detection algorithms for autonomous driving reason about 3D obstacles either from 3D birds-eye view or perspective view or both.

Knowledge Distillation Meets Self-Supervision

2 code implementations ECCV 2020 Guodong Xu, Ziwei Liu, Xiaoxiao Li, Chen Change Loy

Knowledge distillation, which involves extracting the "dark knowledge" from a teacher network to guide the learning of a student network, has emerged as an important technique for model compression and transfer learning.
