Convergence Properties of Score-Based Models using Graduated Optimisation for Linear Inverse Problems

no code implementations29 Apr 2024 Pascal Fernsel, Željko Kereta, Alexander Denker

In this work, we show that score-based generative models (SGMs) can be used in a graduated optimisation framework to solve inverse problems.
