Dual Ascent Diffusion for Inverse Problems

arXiv CS.LG

ArXi:2505.17353v2 Announce Type: replace-cross Ill-posed inverse problems are fundamental in many domains, ranging from astrophysics to medical imaging. Emerging diffusion models provide a powerful prior for solving these problems. Existing maximum-a-posteriori (MAP) or posterior sampling approaches, however, rely on different computational approximations, leading to inaccurate or suboptimal samples. To address this issue, we
