Is Large-scale Pretraining the Secret to Good Domain Generalization?

ICLR 2025poster

Multi-Source Domain Generalization (DG) is the task of training on multiple source domains and achieving high classification performance on unseen target domains. Recent methods combine robust features from web-scale pretrained backbones with new features learned from source data, and this has drama…

Web Artifact Attacks Disrupt Vision Language Models

ICCV 2025poster

Vision-language models (VLMs) (e.g., CLIP, LLaVA) are trained on large-scale, lightly curated web datasets, leading them to learn unintended correlations between semantic concepts and unrelated visual signals. These associations degrade model accuracy by causing predictions to rely on incidental pat…

OCONet: Image Extrapolation by Object Completion

CVPR 2021poster

Image extrapolation extends an input image beyond the originally-captured field of view. Existing methods struggle to extrapolate images with salient objects in the foreground or are limited to very specific objects such as humans, but tend to work well on indoor/outdoor scenes. We introduce OCONet…

Tune It the Right Way: Unsupervised Validation of Domain Adaptation via Soft Neighborhood Density

ICCV 2021poster

Unsupervised domain adaptation (UDA) methods can dramatically improve generalization on unlabeled target domains. However, optimal hyper-parameter selection is critical to achieving high accuracy and avoiding negative transfer. Supervised hyper-parameter validation is not possible without labeled ta…

Understanding Invariance via Feedforward Inversion of Discriminatively Trained Classifiers

ICML 2021spotlight

A discriminatively trained neural net classifier can fit the training data perfectly if all information about its input other than class membership has been discarded prior to the output layer. Surprisingly, past research has discovered that some extraneous visual detail remains in the unnormalized…

Supervised Contrastive Learning

NeurIPS 2020poster

Contrastive learning applied to self-supervised representation learning has seen a resurgence in recent years, leading to state of the art performance in the unsupervised training of deep image models. Modern batch contrastive approaches subsume or significantly outperform traditional contrastive lo…

Boundless: Generative Adversarial Networks for Image Extension

ICCV 2019poster

Image extension models have broad applications in image editing, computational photography and computer graphics. While image inpainting has been extensively studied in the literature, it is challenging to directly apply the state-of-the-art inpainting methods to image extension as they tend to gene…
