Out-of-Distribution Detection Methods Answer the Wrong Questions

Yucen Lily Li, Daohan Lu, Polina Kirichenko +4

To detect distribution shifts and improve model safety, many out-of-distribution (OOD) detection methods rely on the predictive uncertainty or features of supervised models trained…

Modeling Caption Diversity in Contrastive Vision-Language Pretraining

Samuel Lavoie, Polina Kirichenko, Mark Ibrahim +4

There are a thousand ways to caption an image. Contrastive Language Pretraining (CLIP) on the other hand, works by mapping an image and its caption to a single vector -- limiting h…

Understanding the Detrimental Class-level Effects of Data Augmentation

Polina Kirichenko, Mark Ibrahim, Randall Balestriero +4

Data augmentation (DA) encodes invariance and provides implicit regularization critical to a model's performance in image classification tasks. However, while DA improves average a…

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

Megan Richards, Polina Kirichenko, Diane Bouchacourt +1

For more than a decade, researchers have measured progress in object recognition on ImageNet-based generalization benchmarks such as ImageNet-A, -C, and -R. Recent advances in foun…

Chroma-VAE: Mitigating Shortcut Learning with Generative Classifiers

Wanqian Yang, Polina Kirichenko, Micah Goldblum +1

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

On Feature Learning in the Presence of Spurious Correlations

Pavel Izmailov, Polina Kirichenko, Nate Gruver +1

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 lear…
