Geometry-Correct Diffusion Posterior Sampling with Denoiser-Pullback Curvature Guidance and Manifold-Aligned Damping
Researchers present a new diffusion posterior sampling method that improves inverse problem solving by replacing hand-tuned guidance weights with a mathematically principled damped Gauss-Newton correction. The approach demonstrates competitive or superior performance on image reconstruction tasks including accelerated MRI while reducing computational overhead compared to existing methods.
