Spectral Conformal Risk Control: Distribution-Free Tail Guarantees via Bayesian Quadrature

CVPR 2026

Modern vision systems are deployed in settings where occasional catastrophic failures matter more than average accuracy--for example in medical imaging, autonomous driving, and safety monitoring. While conformal prediction gives distribution-free uncertainty guarantees, most existing methods only co

Stable Velocity: A Variance Perspective on Flow Matching

ICML 2026poster

While flow matching is elegant, its reliance on single-sample conditional velocities leads to high-variance training targets that destabilize optimization and slow convergence. By explicitly characterizing this variance, we identify 1) a *high-variance regime* near the prior, where optimization is c…

SymmetricDiffusers: Learning Discrete Diffusion on Finite Symmetric Groups

ICLR 2025oral

The group of permutations $S_n$, also known as the finite symmetric groups, are essential in fields such as combinatorics, physics, and chemistry. However, learning a probability distribution over $S_n$ poses significant challenges due to its intractable size and discrete nature. In this paper, we i…
