Moment Alignment: Unifying Gradient and Hessian Matching for Domain Generalization

UAI 2025

Domain generalization (DG) seeks to develop models that generalize well to unseen target domains, addressing distribution shifts in real-world applications. One line of research in DG focuses on aligning domain-level gradients and Hessians to enhance generalization. However, existing methods are com

Fully Self-Supervised Depth Estimation From Defocus Clue

CVPR 2023poster

Depth-from-defocus (DFD), modeling the relationship between depth and defocus pattern in images, has demonstrated promising performance in depth estimation. Recently, several self-supervised works try to overcome the difficulties in acquiring accurate depth ground-truth. However, they depend on the…

Provable Domain Generalization via Invariant-Feature Subspace Recovery

ICML 2022spotlight

Domain generalization asks for models trained over a set of training environments to perform well in unseen test environments. Recently, a series of algorithms such as Invariant Risk Minimization (IRM) has been proposed for domain generalization. However, Rosenfeld et al. (2021) shows that in a simp…
