Where it stands

Quiet None of the tracked benchmarks has a report from 2025–26.

17 papers in 2023–24 and 6 in 2025–26 (at ICML, NeurIPS, ICLR, CVPR and AAAI); its share of the topic shrank, from 14.5% to 3.6%.

No longer reported by papers here: Set14 ×4 (PSNR, last in 2024); Urban100 ×4 (PSNR, last in 2024); Set5 ×4 (PSNR, last in 2024); Manga109 ×4 (PSNR, last in 2024); Set5 ×2 (PSNR, last in 2024); Set14 ×2 (PSNR, last in 2024).

How this is decided

A benchmark is tracked when at least four papers of this approach report their own method on the same dataset and metric in at least two different years. Its record is the best number reported up to 2024 compared with the best reported in 2025–26: still improving means at least 1% better, flat means at most 0.2% better with at least two papers from 2025–26 trying. Numbers on a different scale from the rest (a fraction among percentages) and far outliers are left out. Results come from different papers with different setups, so they are signals, not head-to-head comparisons. The share of papers is counted at ICML, NeurIPS, ICLR, CVPR and AAAI.

What has been tried

56 papers here report 528 measured changes (a component added, removed or swapped, compared with a baseline): helped 76%, no clear effect 6%, hurt 16%, mixed 3%. Papers mostly publish changes that helped, so "helped" is over-represented.
