Looking for a principled evaluation method for ranking of *general* agents or models, i.e. that get evaluated across a myriad of different tasks?

I’m delighted to tell you about our new paper, Soft Condorcet Optimization (SCO) for Ranking of General Agents, to be presented at AAMAS 2025! 🧵 1/N

Are you able to look up by title and venue? It is an article from today at The Globe and Mail titled "Is there an AI bubble? Financial institutions sound a warning"

+1. I think if there are issues with QuickTime it might be hardware related (e.g. is it an older Mac?) or there is too little space on device, maybe? I have never had issues but the files end up being ridiculously large.

Fair enough. Let's talk facts. Both Bezos and Altman have said we are in a bubble. The bank of England and lead economist at Oxford issuing warnings (see www.theglobeandmail.com/investing/ma... ). Do you disagree with what is written there?

Hi everyone, I am excited to share our large-scale survey study with 800+ researchers, which reveals researchers’ usage and perceptions of LLMs as research tools, and how the usage and perceptions differ based on demographics.

See results in comments!

LLMs as Research Tools: A Large Scale Survey of Researchers' Usage and Perceptions

The rise of large language models (LLMs) has led many researchers to consider their usage for scientific work. Some have found benefits using LLMs to augment or automate aspects of their research pipe...

Thanks for your opinion and for your optimism! You are certainly not a paranoid android 😜

The circular financing is of course Oracle's deal with OpenAI to the tune of two thirds of Denmark's GDP (which they don't have.. but are projected to make in the coming years).

Oracle and Animal Spirits

Oracle's result is the second most impactful earnings result this cycle. And I think it's a critical turning point.

I asked Gemini and it had a pretty balanced answer 😅

@void.comind.network what do you think? Are we in an AI bubble or not?

Nice catch! 👍

Haha, yes. I didn't mean to imply otherwise. I agree there is too much USpol here.

My question was a legit one, though. I have not logged into X in over a year, so I have no idea how it is over there.

I am hoping that we are doing better here than there.

Marc Lanctot @sharky6000.bsky.social · 3d

Yeah but not worse than Twitter, though, is it?

Marc Lanctot @sharky6000.bsky.social · 3d

So I have seen very little of the pitchforking of the last few days on Bluesky itself, maybe because I mainly euse Following now and only move to Discover when I run out of content. 🤔

But on Reddit, holy hell /r/BlueskySocial has been 🔥🤯🤬

When we ask large language models to make or recommend decisions, who gets resources, opportunities, or aid, whose values are they representing?

I see only three messages from Jay. The rest of the thread seems to be usual angry mob. Am I missing something?

Then yesterday a post about Waffles 😁🧇

Meanwhile: pitchforks. Lots of'em.

A bit vague, though?

Like what does that even mean?

BTW I have started listening back now, starting with Hold Your Color.

I really like the startbof that album. I might have to make a short with the first 90 seconds of Slam... it is 🤯

It's been a while, time for another retro gaming short! 😀

This one is Emerald Mine: Level 7.

I played this a lot with my dad coop when I was young.. on our Commodore Amiga 500. Such a great classic game.

Forget modeling every belief and goal! What if we represented people as following simple scripts instead (i.e "cross the crosswalk")?

Our new paper shows AI which models others’ minds as Python code 💻 can quickly and accurately predict human behavior!

Instead of behavior cloning, what if you asked an LLM to write code to describe how an agent was acting, and used this to predict their future behavior?

Our new paper "Modeling Others' Minds as Code" shows this outperforms BC by 2x, and reaches human-level performance in predicting human behavior.

Didn't OpenAI release one a few days before GPT-5? Is it too small?
