Robustness to Spurious Correlations Improves Semantic Out-of-Distribution Detection

no code implementations8 Feb 2023 Lily H. Zhang, Rajesh Ranganath

The detection of shared-nuisance out-of-distribution (SN-OOD) inputs is particularly relevant in real-world applications, as anomalies and in-distribution inputs tend to be captured in the same settings during deployment.

Set Norm and Equivariant Skip Connections: Putting the Deep in Deep Sets

1 code implementation23 Jun 2022 Lily H. Zhang, Veronica Tozzo, John M. Higgins, Rajesh Ranganath

However, we show that existing permutation invariant architectures, Deep Sets and Set Transformer, can suffer from vanishing or exploding gradients when they are deep.

Understanding Failures in Out-of-Distribution Detection with Deep Generative Models

no code implementations14 Jul 2021 Lily H. Zhang, Mark Goldstein, Rajesh Ranganath

Deep generative models (DGMs) seem a natural fit for detecting out-of-distribution (OOD) inputs, but such models have been shown to assign higher probabilities or densities to OOD images than images from the training distribution.

Out-of-distribution Generalization in the Presence of Nuisance-Induced Spurious Correlations

1 code implementation ICLR 2022 Aahlad Puli, Lily H. Zhang, Eric K. Oermann, Rajesh Ranganath

NURD finds a representation from this set that is most informative of the label under the nuisance-randomized distribution, and we prove that this representation achieves the highest performance regardless of the nuisance-label relationship.

Comparing the inferences of diverse candidate models is an essential part of model checking and escaping local optima.
