Out-of-Distribution Generalization via Risk Extrapolation (REx)
David Krueger,Ethan Caballero,Joern-Henrik Jacobsen,Amy Zhang,Jonathan Binas,Dinghuai Zhang,Rémi Le Priol,Aaron Courville +7 more
TL;DR: This work introduces the principle of Risk Extrapolation (REx), and shows conceptually how this principle enables extrapolation, and demonstrates the effectiveness and scalability of instantiations of REx on various OoD generalization tasks.
Exchanging Lessons Between Algorithmic Fairness and Domain Generalization
TL;DR: This work proposes a novel domain generalization method and shows theoretically and empirically how different partitioning schemes can lead to increased or decreased generalization performance, enabling it to outperform Invariant Risk Minimization with handcrafted environments in multiple cases.

Out-of-Distribution Generalization via Risk Extrapolation (REx)
David Krueger,Ethan Caballero,Joern-Henrik Jacobsen,Amy Zhang,Jonathan Binas,Dinghuai Zhang,Rémi Le Priol,Aaron Courville +7 more
TL;DR: In this paper, risk extrapolation is used as a form of robust optimization over a perturbation set of extrapolated domains, and a penalty on the variance of training risks (V-REx) is proposed as a simpler variant.
