Rate-Distortion-Perception Theory: Redefining the Fundamental Limits of Information Representation

Photios A. Stavrou, Giuseppe Serra, Marios Kountouris

Classical rate-distortion (RD) theory has long established the fundamental limits of lossy compression by quantifying the minimum number of bits required to represent a source under a prescribed distortion constraint. However, widely used distortion measures such as mean-squared…

LeVLJEPA: End-to-End Vision-Language Pretraining Without Negatives

Lukas Kuhn, Giuseppe Serra, Randall Balestriero, Florian Buettner

Vision-language pretraining remains dominated by contrastive objectives, whereas vision-only self-supervised learning has largely adopted non-contrastive methods. At the same time, the role of vision-language encoders has shifted: they are increasingly deployed not as zero-shot c…
