AISTATS Supplementary

Use this when assembling AISTATS supplementary material. The supplement can support the paper, but the main submission must remain understandable without it.

Supplement structure

• Put theorem proofs, derivations, extra ablations, simulation details, dataset

documentation, and robustness tables in a clean appendix or supplementary manuscript.

• Put executable assets in a separate archive when current OpenReview forms allow it.
• Respect the current supplementary deadline. AISTATS 2026 placed supplementary-material

submission after the paper deadline but before review.

• Keep all supplementary files double-blind: no authors, institutions, acknowledgements,

private paths, repository owners, grants, or identifying metadata.

• Do not use the supplement to hide essential motivation, core method description, main

theorem statements, or primary empirical results.

• Verify archives open on a clean machine and contain no credentials, cache directories,

large irrelevant files, or hidden OS metadata.

Appendix architecture for proofs

• Order appendix sections to mirror main-text theorem order; statistician reviewers navigate

by theorem number, not by page.

• Restate each theorem before its proof so the appendix reads standalone without flipping

back to the two-column body.

• Standard partition: notation and assumptions, main proofs, auxiliary lemmas, additional

simulations, then real-data details.

• Keep one proof-sketch paragraph per major theorem in the body itself; an AISTATS submission

whose entire argument lives in the supplement reads as unreviewable within the page limit.

• Cross-reference every appendix table and lemma from the body at least once; orphaned

supplement material is invisible to reviewers and wasted under reviewer discretion.

• If the cycle allows appendices inside the main PDF after the references, confirm against

the current instructions whether that or a separate file upload is expected.

What gets opened first

| Supplement item | Inspection likelihood | Practical implication | |---|---|---| | Proof of the headline theorem | High | Polish it to main-text standard | | Extra ablation and robustness tables | Medium | Reference each one from the body | | Code archive | Variable, reviewer discretion | The README must orient a reader in one minute | | Raw experiment logs | Low | Include for completeness, never rely on them |

Vignette: splitting an optimization paper

A submission proving a convergence guarantee for a stochastic mirror-descent variant, plus benchmark plots: the body keeps the theorem, the key lemma, the proof roadmap, and two decision-critical figures; the appendix holds full proofs and step-size sensitivity grids; the archive carries the seeded experiment runner. Nothing decision-critical lives only in the archive, because archive inspection at AISTATS is discretionary.
