Slow convergence behavior: MACE with qGGMRF prior #123

Open dyang37 opened 1 year ago

dyang37 commented 1 year ago

When testing MACE with qGGMRF denoiser, we observed that while the converged result seems correct (in the sense that it is close to MBIR recon result), the convergence is slow. See the slides below for the experiment details (this is included in Lilly weekly update slides on 02/23/2023). mace_qGGMRF_slow_convergence.pptx

Per Dr. Buzzard's request, I'm recording this issue here, so that we do not lose track of it.

Yes, this qGGMRF prior should be extremely useful for optimization and debugging.
