AISTATS Reproducibility

Use this before submission and again before camera-ready. Reopen the current CFP and OpenReview forms to confirm whether a reproducibility checklist is required.

Evidence map

• Map each theorem, algorithmic claim, simulation claim, and empirical claim to a verifiable

location in the paper, appendix, supplement, or artifact package.

• For theory, state assumptions, proof dependencies, convergence conditions, constants, and

failure modes clearly enough for statistical readers.

• For experiments, report datasets, splits, preprocessing, evaluation metrics, baselines,

hyperparameter ranges, final selected settings, seeds, repeated runs, compute, and runtime.

• For small performance differences, add uncertainty estimates: standard errors, confidence

intervals, paired tests, bootstrap intervals, or repeated trials as appropriate.

• Explain missing code/data honestly and describe how a reader could reproduce the analysis

in principle.

• Keep the checklist consistent with the manuscript; contradictions between checklist and

paper are review-risk multipliers.

Checklist-to-claim audit table

| Checklist item | Pure-theory answer | Theory-plus-experiments answer | |---|---|---| | Code availability | NA only if there is literally no computation | Anonymous archive, or an honest stated reason | | Assumptions stated | Every theorem lists its conditions inline | Plus a note on which experiments satisfy them | | Error bars | NA for deterministic results | Required for every stochastic figure and table | | Compute resources | NA | Hardware, runtime, and total number of runs |

Marking NA on an item the paper actually triggers is a recognizable AISTATS red flag, because reviewers cross-check checklist answers against the PDF and read contradictions as carelessness about the rest of the paper.

Vignette: a rates-plus-simulation paper

Consider a submission proving posterior contraction rates for a Bayesian nonparametric model, validated by MCMC simulation. Its reproducibility spine: prior hyperparameters and their selection rule, chain length, burn-in, convergence diagnostics, replication seeds, and a statement of which contraction-theorem conditions the simulated model satisfies — plus one honest sentence about the condition it does not.

Degrees of reproducibility

• Turnkey: one command regenerates each figure from logged seeds.
• Scripted: scripts exist but require documented manual steps or external data access.
• Descriptive: prose detailed enough that a competent reader could rebuild the pipeline.

For AISTATS, simulations should be turnkey because statistician reviewers actually rerun them; large real-data pipelines may stay scripted with deviations documented. Stating the achieved level honestly beats overpromising turnkey behavior that fails on a clean machine.
