Reproducibility Checklists in Practice: A Three-Year Audit

Ingrid Novak, Carlos Medina

OPENAIR 2026 · pp. 1–12 · 9 November 2026 · 10.xxxx/ctm.pr.2026.0011

We audit 2,400 checklist responses submitted over three years and compare them against the papers they accompany. Checks for compute reporting and variance were answered affirmatively in 78% of cases but supported by the paper in only 41%, suggesting that checklists work best when responses must point to a location in the text.

A Taxonomy of Evaluation Leakage in Language-Model Benchmarks

Nadia Haddad, Ingrid Novak, Kofi Mensah

Version 2 (updated) · 14 October 2026 · 10.xxxx/ctm.pp.2026.0004

Benchmark scores can be inflated when test material reaches the training data or when evaluation choices quietly favour a model. We review 140 papers and incident reports and organise the mechanisms of evaluation leakage into a taxonomy with four top-level classes and eleven sub-classes. For each class we summarise how it can be detected, how often it has been reported, and what practices reduce its likelihood.

Statistical Power in Agent Benchmarks: How Many Runs Are Enough?

Hana Kovács, Kofi Mensah, Carlos Medina

Version 2 · 3 reviewer reports · 14 August 2026 · 10.xxxx/ctm.pb.2026.0008

Most agent benchmarks report one run per task, yet agents are stochastic. We analyse run-to-run variance on four public agent benchmarks and derive the number of repeated runs needed to detect a given difference between two systems at conventional power. For differences smaller than five points, single-run comparisons have less than 40% power on all four benchmarks. We provide a sequential testing procedure that stops early when the evidence is clear, and show that it halves the cost of repeated evaluation while keeping the false-positive rate below 5%.

Reproducibility-Checklist Compliance in Machine-Learning Papers: A technical report on what authors state and what they release

Ingrid Novak, Kofi Mensah

Version 1 · 27 July 2026 · 10.xxxx/ctm.pp.2026.0002

Many machine-learning venues now require authors to complete a reproducibility checklist. We audited 240 papers that ticked the item “code is provided” and checked whether the linked repositories existed, ran and reproduced the headline table. 87% had a reachable repository, 58% contained instructions sufficient to run training or evaluation, and 31% reproduced the headline result within the reported variance. Compliance was higher for papers reporting variance across seeds. We recommend checks that can be automated at submission time.

Open Research Data in Machine Learning: A handbook

Fatima Zahra El Idrissi, Ravi Menon, Ingrid Novak

1st edition · 186 pages · ISBN 978-0-00-100003-6 · 24 April 2026 · 10.xxxx/ctm.bk.2026.0003

A step-by-step handbook for sharing datasets, code and models so that others can find, cite and reuse them. It covers licences, documentation, identifiers, repositories, privacy, and long-term preservation, with checklists that can be adopted by labs and venues.
