"LLMs broadly align with human category boundaries, yet fall short on fine-grained semantic distinctions. Unlike humans, ... LLMs aggressively compress, achieving more optimal information-theoretic compression at the cost of semantic richness." arxiv.org/abs/2505.17117

You can’t “fix” X, The Everything App by going back and posting there because the owner has this thumb on the scale of the algorithm to promote the worst ideas and people. It’s not a viable solution, you have to let it go.

I always thought that the language mixing during reasoning is fascinating and whether it's actually a way that LLMs optimize its reasoning. Just came across a study on this: arxiv.org/abs/2507.15849

This experiment can produce interesting data...

Announcing the ICML 2026 policy for LLMs in reviewing! Reviewers and authors both pick either conservative or permissive LLM use, and will be matched accordingly. Importantly: authors on papers who choose conservative must obey the conservative policy as reviewers.

New paper out in @science.org! We unveil the online manipulation market with the Cambridge Online Trust & Safety Index (COTSI). We show in real time the cost of purchasing fake accounts across every social platform around the world - so they can be held accountable www.science.org/doi/10.1126/...

"it is possible for machines to discover a state-of-the-art RL rule that outperforms manually designed rules. This was achieved by meta-learning from the cumulative experiences of a population of agents across a large number of complex environments." www.nature.com/articles/s41...

"What?" was my first reaction, but maybe this is *roughly* the right direction in a world where 'generation' becomes ever cheaper while 'evaluation' remains difficult. But financial incentives may also attract more AI review slops. Will they be able to reliably root out AI review slops?

@cvillecityhall.bsky.social is on track to miss its own comprehensive plan & climate goals while budgeting so little for bike infra due to failure to identify projects. I wrote a letter urging Council to fund a connected, protected network—not another decade of failure yyahn.com/wiki/article...

If anyone is curious about the current list of search terms being used by right wing activist organizations to harass university professors, here's a public records request I received today from Mike Howell of the Heritage Foundation. Not intimidating or meant to curtail by my speech at all, right?

I’m pleased to share the Second Key Update to the International AI Safety Report, which outlines how AI developers, researchers, and policymakers are approaching technical risk management for general-purpose AI systems. (1/6)

Summary: a (rather simple) AI bot can not only successfully evade survey-level protections, it can also mimic personas accurately across questions, parse photos/videos, and infer the researcher’s hypotheses to produce data that confirms them. The official paper link: www.pnas.org/doi/10.1073/...

I’m really excited about our release of Gemini 3 today, the result of hard work by many, many people in the Gemini team and all across Google! 🎊 blog.google/products/gem... Gemini 3 performs quite well on a wide range of benchmarks.

NEW: The Tate brothers, who have been accused of sexual misconduct in three countries, had their devices seized by law enforcement when they arrived in the U.S. Days later, a White House official told DHS to return them.

If women are underrepresented in STEM, it's at least partly because men like this offer mentoring, then embarrass themselves by assuming their mentees must be into them, then decide the best solution is to cut ties, which sends the signal to other faculty that the mentee must not be good enough.

I see the point of the commentary but am not so sure about these examples... Isn't the PCA doing what it's supposed to do in these examples? (I often use "finding the most informative perspective to look at a fish" as an intuitive way to understand PCA.) www.pnas.org/doi/10.1073/...

The emails have Summers reporting to Epstein about his attempts to date a Harvard economics student & to hit on her during a seminar she was giving.

I'm a longtime fan of Not Just Bikes, but his 95(!) minute video on John Forester and Vehicular Cycling is truly his magnum opus. If you are even remotely interested in the history of bicycling in America, it is worth a watch. www.youtube.com/watch?v=pRPd...

In the name of protecting Jews, Jews have their funding cancelled, get kicked out of seminars, and are removed from leadership positions in Jewish Studies to be replaced by non-Jews.

Hey 👋🏽 Cville peeps! If you haven't voted yet, be sure to get out on TUESDAY, NOVEMBER 4 to vote. Voting is, admittedly, a rather limited way to build political power, but it's still a really important one. Here's the sample ballot for Cville. Next up, I'll share who I'm voting for, and why

Federal Judges— or staff, but same-same— used "AI" to summarize & draft rulings, issued them w/o checking the work, leading to basic factual errors, & thus undermining the facticity & validity of the rulings entire. Gee. Who Could Have Foreseen. *stares directly into the camera like in the office*
