Figure 2: Fields vary widely in their consensus around top-5 venues and the general alignment of their prefer- ences. Whether one uses a field-level ranking constructed from the pairwise comparisons of all respondents in a field to predict an individual’s pairwise comparisons (horizontal axis) or assesses the degree to which individuals in a field agree on a top-5 (vertical axis), some fields (e.g. Economics) demonstrate a much more overlapping and organized set of preferences than others (e.g. Computer science).

Academic fields differ in their degree of consensus about what "better" publication venues are β€” here shown both for consensus about the "top 5" and for pairwise choices.

CAM Sermons

I often write "sermons" to our applied math PhD students as part of my Friday roundup email. This week, I wrote about the use of AI (and specifically LLMs) in applied math research:

Benchmarks Saturate When The Model Gets Smarter Than The Judge arxiv.org/pdf/2601.19532 may be worth a look? Recent preprint which looks specifically at LLM-as-judge failures for the Omni-MATH dataset

We actually found (following some earlier work) that the pairwise/pointwise difference does not actually matter that much, and the intuition that pairwise judgments are better because they have a reference point may not hold true

Dear hivemind,
Do you have any favorite references on failures of LLM-as-a-judge (and universally enforceable validity checks? besides some kind of cohen's kappa on a small subset)

β€œIn the last year, it’s gotten a lot worse” A Qualitative Investigation of Barriers to Disability Benefits in 2025 - DREDF This report is based on interviews with 52 benefits professionals serving over 8,000 disability claimants nationwide. The independent research finds that recent Social Security Administration administ...

In this new report, @ksavin.bsky.social, and @calliefreitag.bsky.social and I explain how Trump 2.0 and DOGE built up new barriers to the already-difficult process of getting disability benefits.

Let's talk about what we found, and what we recommend to address the issues. 🧡

Today arXiv remembers our colleague Joe Halpern, who was instrumental in founding arXiv's CS section.

Joe's passions ranged far & wide and we're lucky that arXiv was one of them. Joe, thank you for giving so much to arXiv - you are missed.

the past couple of years I've spent a lot of time digging into applied collaborations/projects. I feel like a lot of theory-first people write this off as not a valuable mode of thinking, but the truth is I find it useful for me to believe in something, and it's certainly not techco's narratives atm
