This paper proposes a new optimization algorithm, ProjDiff, which leverages the denoising capability of diffusion models to improve the precision of learnable priors in inverse problems. The authors introduce an auxiliary optimization variable to reframed noisy inverse problems as a two-variable constrained optimization task. They use gradient truncation and projection gradient descent to solve this problem efficiently. Experiment results show that ProjDiff outperforms previous methods on various linear and nonlinear inverse problems, including image restoration, source separation, and partial generation tasks.

Inverse problems are challenging tasks in machine learning. Researchers have been working on finding better ways to solve these problems. One approach is to use diffusion models, which can help improve the results. However, existing methods don’t fully utilize the potential of diffusion models. This paper proposes a new algorithm that combines the strengths of both. The result is an efficient and accurate way to solve inverse problems.
