DLSS 5 is all over the timeline, and for good reason. In my internship at @AIatMeta we had the same idea: use a video model as a learned second-stage renderer on top of game engines. In our paper RealMaster, we make synthetic video look real while preserving scene fidelity 👇
The initial noise in diffusion models is surprisingly correlated with the final image. Our NoisePrints paper exploits this to provide a lightweight, distortion-free, cryptographically secure watermark for proving authorship of generated images & videos, requiring no model access.
Everyone uses CFG with w = 7.5… but why?? 🤔 For non-trivial prompts, choosing w is hard: too low → weak alignment, too high → artifacts. We show w shouldn’t be fixed — it should adapt! ✨ We present a tiny but smart MLP to adjust w over time → Better images/alignment 🚀 1/n
