New DDR framework enhances out-of-distribution detection with diffusion models

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new framework called DDR for out-of-distribution (OoD) detection using diffusion models. This method assesses discrepancies not in the raw image space, but within the representation spaces of the classifier being protected. DDR quantifies feature-level covariate discrepancy and logit-level concept discrepancy, refining the diffusion model's generation to improve detection accuracy. Experiments on ImageNet-1K show DDR outperforms existing methods. AI

IMPACT Introduces a novel approach to improve the reliability of AI models by enhancing their ability to identify unfamiliar data.

    Beyond Perceptual Distance: Discrepancy Assessment on Deep Representation for Out-of-Distribution Detection with Diffusion Model

    arXiv:2409.10094v3 Announce Type: replace-cross Abstract: Out-of-Distribution (OoD) detection aims to justify whether a given sample is from the training distribution of the classifier-under-protection, i.e., In-Distribution (InD), or from an unknown out distribution. Recent rese…
