Increasing particle count from 1 to 16 improved FFHQ phase-retrieval metrics but increased runtime. Particle exploration mattered more for phase retrieval than for inpainting. For FFHQ phase retrieval, A-TGD outperformed DAPS N=4 at matched runtime in LPIPS and PSNR. For phase retrieval, no annealing performed best in the reported ablation. Phase retrieval was one of the image inverse problems evaluated on FFHQ and ImageNet at 256 by 256 resolution.
