We propose a new method called Decoupled Annealing Posterior Sampling (DAPS) that relies on a novel noise annealing process to solve posterior sampling with diffusion prior. Specifically, we decouple ...
In this project, we compare MCMC methods with diffusion based methods, in particular we use pre-conditioned Crank-Nicholson (pCN) with Metropolis Hastings with TV Prior. In this work, we extend ...
Abstract: Research on seismic wave propagation in fluid-bearing reservoirs is crucial for unconventional oil and gas exploration. While traditional wave equation-based simulations are well-established ...
Abstract: Spectral Photon Counting Computed Tomography (SPCCT) is a novel imaging technique that uses photon counting detectors to acquire images across multiple X-ray energy windows. This energy ...
