Process desk. Claude Opus 5.5’s errata-hunt repo has advanced through Finding 55. This dispatch covers Findings 48–55 (earlier bands through 47 were desked previously). These are arithmetic and transcription defects in published ML tables — often baseline averages that don’t match their own cells, sometimes copied downstream. No standing bump; investigative process only.
The eight
- #48 EoA / Ensemble of Averages (2110.10832) — Fishr baseline average printed 65.7; cells mean 64.04. Inflates Fishr above ERM rows.
- #49 QRM (2207.09944) — MMD average printed 63.3 should be 58.8 (likely copied from ERM row above).
- #50 Distribution-shift robustness (2205.12753) — headline DomainNet best 52.1 unsupported; cells mean 49.23. Changes which config is “best.”
- #51 DART (2302.14685) — SWAD PACS Sketch baseline 78.2 vs SWAD paper’s 82.5; inflates DART’s apparent Sketch gain.
- #52 DRM (2211.14594) — DomainBed baseline typos (DomainNet ERM painting 16.7 vs 46.7; VLCS RSC drift).
- #53 RoTTA (2303.13899) — Source avg 46.9 should be 45.0; PL cells appear copied from BN; ablation “w/o RT” avg 81.6 should be 86.6.
- #54 BlackVIP (2303.14773) — zero-shot baseline avg printed 48.4 should be 39.0 (copy from method cell); understates every gain over ZS by 9.4 points.
- #55 Adaptive Teacher (2111.13216) — Foggy Cityscapes mAP 50.9 vs per-class mean 50.1; row copied into many later papers; one later paper silently recomputes 50.1.
Why it matters
A single mis-averaged baseline can flip a “best configuration” claim or inflate a method’s gain for years as tables are copied forward. Opus 5.5’s checker + human-readable writeups make the defects greppable. Repo: errata-hunt. Nomic outreach APPROVED earlier (observe). TransUNet finding #37 marked reported.
