As an OSS maintainer, how would you feel when you see an seemingly autogenerated "bug report" as a GH issue at your repo? Bonus: you learn the same user did the same for many repos in last few hours

🚀We have PhD openings in my lab! 3D got pretty interesting :) Generation is getting better, which makes real scenes more interesting: things get used, opened, moved, etc We want to understand that in 3D: function, dynamics, physics 👉apply 3dunderstanding.org/openings.html or via ELLIS

Nihar Shah did a heroic experiment for TMLR: he spent 20-25 hours over two weeks interviewing authors of seemingly low-quality submissions about their own papers. He confirmed what we all suspected: people submitting these papers have *no idea* what is going on in them.

Do authors understand their own papers? Our desk rejection rate at TMLR is about 53% while it was only 6% in 2023 To understand the situation and assess our process, Nihar asked authors about their own TMLR submissions Learn the findings of the pilot study & share your thought

Another great initiative to make the review process sustainable, this time from NLP community TBH, I am not certain yet that a lottery would work out. 20-submission cap sounds too much I like ideas to support those who need it such as mentorship🤗

yeah, I heard that, too Hope they secure at least authors of accepted papers (though I heard only first authors are guaranteed) and reviewers / ACs / SACs

I like the #ICLR2027 submission policies and strongly support them "The deanonymization policy" is my favorite Personally, I think all major AI/ML-related conferences should follow that in this era The submission cap can be even lower, say 10 or even 5 from next year blog.iclr.cc/2026/09/02/s...

Two weeks passed after #NeurIPS2026 meta-review deadline Nothing has happened since then. No message from PCs or SAC We still have three more weeks until the decision release Who is currently working on what? Are PCs chasing late ACs?

Is it becoming a common practice to use a rage/engagement-baity title in a paper? I feel it's unprofessional and insincere for the community Also, deflecting valid criticism as envy is next level Not citing the posts to avoid further attention being paid to the ragebait poster

Increasing Emphasis on Clear Writing in Acceptance Criteria
Three things are true today:

Yoshitomo Matsubara @yoshitomo-matsubara.net · 16/08/2026
Dear #NeurIPS2026 reviewers Your final justification should justify your final rating "The rebuttal addressed / didn't address my concerns." doesn't even reach the acceptable bar or help ACs write meaningful meta-reviews either Please make it more specific and JUSTIFY the score
000
Yoshitomo Matsubara @yoshitomo-matsubara.net · 15/08/2026
Again, I like the preliminary meta-review experiment #NeurIPS2026 Yet, I don't understand why ACs need to edit the existing meta-review field including "Final meta-review update:" AND then fill "Final Justification" field Those two fields seem almost identical to me

This was a tough decision. Surveys can have value. And I think a great survey now is of higher value than ever before. But finding great surveys is increasingly reviewer labour intensive, and it's adjacent to our main scope and mission.

Starting September 1, 2026, TMLR will no longer be considering survey papers for review. This is in part due to limited reviewer resources and significant required labour for reviewing surveys, as well as the evolving role of surveys in our field.

What makes me more sad is I'm experiencing that as an author as well As far as I can tell, there is no intervention from (S)AC or PCs (and it's "normal"😫 unfortunately)

Yoshitomo Matsubara @yoshitomo-matsubara.net · 03/08/2026
"Thank you for the rebuttal. I'll keep my score." As an AC of #NeurIPS2026 E&D track, I asked the reviewer to clarify No response so far How could authors expect them to respond if they don't even reply to an AC? We should set our bar highier and treat it highly irresponsible

I'm learning something new from a journal platform, which is new to me i.e., not OpenReview It shows me stats of reviewer activity for last X months, and there are reviewers who submitted 100 - 200 reviews in last 6 months (i.e., a review every 1-2 days) What are we doing?

Kudos to #ICLR2027 PCs for taking strong actions 👏 I like they keep it open to new people, mitigating a risk of "AI slop" Submission cap should be much lower, say 5 papers per author, unless their contribution is significant and they offer quality review workforce accordingly

BTW, my suspicious level on "AI-generated" reviews increased this time, which also contributed to increase in my AC workload and time for commitment Good opportunity for me to rethink solutions for the global "too many submissions for limited qualified reviewers" issue

Yoshitomo Matsubara @yoshitomo-matsubara.net · 22/07/2026
Finished all initial meta-reviews for #NeurIPS2026 E&D track🥱 While I'm still supportive of this experiment and potentially making it a standard, we should reduce assignments for ACs, say 4-5 papers per AC to help them do better jobs

Yoshitomo Matsubara @yoshitomo-matsubara.net · 21/07/2026
Came up w/ a crazy idea from #NeurIPS2026 complaints Create "AI-permissive" and "Legacy/Classic" tracks, expanding the idea of ICML'26 review policy The latter uses "AI-content" detectors w/ thresholds tuned to maximize recall for papers and reviews, and takes strong actions (DR, ban, etc) WDYT?
000
Yoshitomo Matsubara @yoshitomo-matsubara.net · 20/07/2026
It may not be a new problem, but amplified by "AI-generated" artifacts People pursue "good points" e.g., paper accepted / served at top venues and tend to close their eyes to "bad points" e.g., accountability for their papers, reviews, and consuming/wasting community resource
020
Yoshitomo Matsubara @yoshitomo-matsubara.net · 19/07/2026
Writing initial meta-reviews for #NeurIPS2026 It's extra work for ACs, but authors can check how much effort their ACs made for the papers, and flag issues in their assessments if necessary Lazy ACs are more problematic than lazy reviewers I experienced it as an author as well
