A Geometric Framework for Understanding Memorization in Generative Models

ICLR 2025spotlight

As deep generative models have progressed, recent work has shown them to be capable of memorizing and reproducing training datapoints when deployed. These findings call into question the usability of generative models, especially in light of the legal and privacy risks brought about by memorization.…

Self-supervised Representation Learning from Random Data Projectors

ICLR 2024poster

Self-supervised representation learning (SSRL) has advanced considerably by exploiting the transformation invariance assumption under artificially designed data augmentations. While augmentation-based SSRL algorithms push the boundaries of performance in computer vision and natural language processi…

Exposing flaws of generative model evaluation metrics and their unfair treatment of diffusion models

NeurIPS 2023poster

We systematically study a wide variety of generative models spanning semantically-diverse image datasets to understand and improve the feature extractors and metrics used to evaluate them. Using best practices in psychophysics, we measure human perception of image realism for generated samples by co…
