Constrained Particle Seeking: Solving Diffusion Inverse Problems with Just Forward Passes

AAAI 2026technical

Diffusion models have gained prominence as powerful generative tools for solving inverse problems due to their ability to model complex data distributions. However, existing methods typically rely on complete knowledge of the forward observation process to compute gradients for guided sampling, limi

Hybrid Regularization Improves Diffusion-based Inverse Problem Solving

ICLR 2025poster

Diffusion models, recognized for their effectiveness as generative priors, have become essential tools for addressing a wide range of visual challenges. Recently, there has been a surge of interest in leveraging Denoising processes for Regularization (DR) to solve inverse problems. However, existing…

Physics-aligned field reconstruction with diffusion bridge

ICLR 2025spotlight

The reconstruction of physical fields from sparse measurements is pivotal in both scientific research and engineering applications. Traditional methods are increasingly supplemented by deep learning models due to their efficacy in extracting features from data. However, except for the low accuracy o…
