Exploring Transferability for Randomized Smoothing

no code implementations14 Dec 2023 Kai Qiu, Huishuai Zhang, Zhirong Wu, Stephen Lin

However, the model robustness, which is a critical aspect for safety, is often optimized for each specific task rather than at the pretraining stage.

Weakly-supervised Pre-training for 3D Human Pose Estimation via Perspective Knowledge
