COLT 2026

Annual Conference on Learning Theory

June 29 - July 3, 2026San Diego, CaliforniaOfficial conference site Site reachable

COLT 2026 is the 39th Annual Conference on Learning Theory, focusing on theoretical aspects of machine learning at the intersection of computer science, statistics, and applied mathematics. It welcomes submissions that advance the understanding of learnability, optimization, and empirical phenomena in learning, with an inclusive view of learning theory that spans classical and emerging domains.

Contribution paths

A strong submission should clearly identify its contribution and evaluate it appropriately.

Full Paper

Submissions must be a single PDF with a main body limited to 12 PMLR-formatted pages (excluding references). All proofs and details must be included, possibly in appendices, but novelty and significance are judged primarily on the main paper.

1-Page Extended Abstract

Authors of accepted papers may opt out of the full proceedings in favor of a 1-page extended abstract pointing to an open access archival version of the full paper reviewed for COLT.

Policies worth checking twice

  • Submissions must be anonymized for double-blind review: no author names or identifying information in the submission.
  • The main paper is limited to 12 PMLR-formatted pages; references and appendices have no page limit.
  • All proofs and derivations required to substantiate results must be included in the submission.
  • Dual submissions to other peer-reviewed conferences with proceedings are prohibited.
  • Dual submissions to journals are prohibited; COLT submissions may not be submitted to a journal until after decisions are released or withdrawn.
  • At least one author of each accepted paper must attend the conference in person to present the work.
  • Authors may use large language models (LLMs) for writing, mathematics, and research, but must disclose unusual contributions and remain responsible for correctness.
  • Reviewers must not share submissions with any LLM.
