Excited to share that today our paper recommender platform www.scholar-inbox.com has reached 20k users! We hope to reach 100k by the end of the year.. Lots of new features are being worked on currently and rolled out soon.

Interesting, it appears the #ICCV2025 submission and supplementary materials deadlines are the SAME.

💡 Theoretical Insights: We show that our uncertainty estimates are related to the second-order derivative of the diffusion noise distribution, providing a solid mathematical foundation.

🎯 Guided sampling: We use uncertainty estimates to drive the sampling process towards higher quality generations, resulting in improved FID results and fewer artefacts.

Key highlights:

📊 Training-free uncertainty: Our method estimates pixel-wise aleatoric uncertainty during the sampling phase without requiring any model modifications or additional training, allowing to filter out low quality samples.
