Reproducibility Variable Result LLM Response
Research Type Experimental On the unconditional CIFAR10 dataset, we obtain an Inception score of 9.46 and a state-of-the-art FID score of 3.17. On 256x256 LSUN, we obtain sample quality similar to Progressive GAN.

Pseudocode Yes Algorithm 1 Training and Algorithm 2 Sampling are presented in the paper.
Open Source Code Yes Our implementation is available at https://github.com/hojonathanho/diffusion.
Open Datasets Yes On the unconditional CIFAR10 dataset, we obtain an Inception score of 9.46 and a state-of-the-art FID score of 3.17. On 256x256 LSUN, we obtain sample quality similar to Progressive GAN.
Dataset Splits No The paper mentions 'train' and 'test' in Table 1 (NLL Test (Train)) and 'training set' and 'test set' in Section 4.1 but does not provide specific split percentages, sample counts, or a detailed splitting methodology for reproducibility.
Hardware Specification No Google s Tensor Flow Research Cloud (TFRC) provided Cloud TPUs. This mentions the type of hardware (Cloud TPUs) but lacks specific details such as the model or version of the TPUs, or any CPU/GPU specs or memory amounts.
Software Dependencies No The paper mentions software components and methods like 'U-Net backbone', 'Pixel CNN++', 'group normalization', and 'Adam', but it does not provide specific version numbers for any libraries, frameworks, or solvers used.
Experiment Setup Yes We set T = 1000 for all experiments so that the number of neural network evaluations needed during sampling matches previous work [53, 55]. We set the forward process variances to constants increasing linearly from β1 = 10 4 to βT = 0.02. Algorithm 1 displays the complete training procedure with this simplified objective.
