Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in Coakley et alK. L. Coakley, T. Snelleman, H. Hoos, and O. E. Gundersen, "The Shift Toward Open and Reproducible AI Research," Under Review, 2026. doi: 10.48550/arXiv.2606.16974..

Pseudocode Yes Algorithm 1 DDIM sampler (Song et al., 2020a) Require: (σN, . . . , σ0), x N N(0, I), ϵθ Ensure: Compute x0 with N evaluations of ϵθ for t = N, . . . , 1 do xt 1 xt + (σt 1 σt)ϵθ(xt, σt) return x0
Open Source Code Yes Code for the experiments is available at https: //github.com/Toyota Research Institute/ gradient-estimation-sampler
Open Datasets Yes We use denoisers from (Ho et al., 2020; Song et al., 2020a) that were pretrained on the CIFAR10 (32x32) and Celeb A (64x64) datasets (Krizhevsky et al., 2009; Liu et al., 2015).
Dataset Splits No The paper mentions using 'training images' and evaluating on the 'MS COCO validation set', but does not provide specific details on train/validation/test splits for the datasets used to train or evaluate their models.
Hardware Specification Yes All the experiments were run on a single Nvidia RTX 4090 GPU.
Software Dependencies Yes We also use Stable Diffusion 2.1 provided in https://huggingface.co/stabilityai/stable-diffusion-2-1.
Experiment Setup Yes For the CIFAR-10 and Celeb A models, we choose σ1 = q σDDIM(N) 1 and σ0 = 0.01. For CIFAR-10 N = 5, 10, 20, 50 we choose σN = 40 and for Celeb A N = 5, 10, 20, 50 we choose σN = 40, 80, 100, 120 respectively. For Stable Diffusion, we use the same sigma schedule as that in DDIM. ... We found that setting γ = 2 works well for N < 20; for larger N slightly increasing γ also improves sample quality (see Appendix E for more details).
