Does Progress On Object Recognition Benchmarks Improve Real-World Generalization?

no code implementations24 Jul 2023 Megan Richards, Polina Kirichenko, Diane Bouchacourt, Mark Ibrahim

Second, we study model generalization across geographies by measuring the disparities in performance across regions, a more fine-grained measure of real world generalization.

Chroma-VAE: Mitigating Shortcut Learning with Generative Classifiers

no code implementations28 Nov 2022 Wanqian Yang, Polina Kirichenko, Micah Goldblum, Andrew Gordon Wilson

Deep neural networks are susceptible to shortcut learning, using simple features to achieve low training loss without discovering essential semantic structure.

On Feature Learning in the Presence of Spurious Correlations

1 code implementation20 Oct 2022 Pavel Izmailov, Polina Kirichenko, Nate Gruver, Andrew Gordon Wilson

Deep classifiers are known to rely on spurious features $\unicode{x2013}$ patterns which are correlated with the target on the training data but not inherently relevant to the learning problem, such as the image backgrounds when classifying the foregrounds.

Task-agnostic Continual Learning with Hybrid Probabilistic Models

no code implementations ICML Workshop INNF 2021 Polina Kirichenko, Mehrdad Farajtabar, Dushyant Rao, Balaji Lakshminarayanan, Nir Levine, Ang Li, Huiyi Hu, Andrew Gordon Wilson, Razvan Pascanu

Learning new tasks continuously without forgetting on a constantly changing data distribution is essential for real-world problems but extremely challenging for modern deep learning.
