Excited to be on sabbatical visiting @Yale for the 24-25 academic year! First day in my @yaledatascience office high in Kline tower, overlooking East Rock. Still getting settled, but if you're here and want to chat, hit me up!

🚨Maine Primary Forecast 🚨

Polls show the crowded Maine primaries are in a dead heat heading into June 9. But Maine uses ranked-choice voting, and these polls focus only on first choices.

Today, my collaborators and I released ranked-choice forecasts 👇

@plopnl @jgitchell @yaledatascience Hello! PNAS published the paper faster than we expected; the code is public but double checking that we properly cleaned the data is taking a bit of time — please check back in a week and/or email me and I’ll be happy to send you a note when it’s posted!

By far the best commentary on this drama. Thank you!

Also, the SuperNotes paper is extremely interesting. There are so many awful ideas in the LLMs-for-combatting-misinformation space but this seems really well thought out. https://t.co/byT7kUeR0R By @actuallysoham, @jaybaxter, @bakkermichiel @msaveski.

I hope CN team is working on actually piloting it on X rather than leaving it as a research paper!

After many conversations with artists and many hours in the art library, this essay is the result. Things also got delightfully weird when we tried to decide how to randomize author order. I'm pretty sure this is the first paper with an author order determined by tarot! 4/4

Now up on HDSR, "The Art of Randomness: Sampling and Chance in the Age of Algorithmic Reproduction", a collaboration with @_ziv_e where we examine the stochastic nature of AI tools by connecting to the history of chance aesthetics: https://t.co/sl2j2o7msm 1/

[Johan Ugander @jugander]

When @_ziv_e started as a postdoc at Stanford, I unloaded some of my thoughts on him, and he became super energized by how it aligned with challenges he'd been thinking about in the modern AI art space. See his 2023 collaborative perspective in Science: https://t.co/6zaHGJNWeC 3/

@dianarycai Very cool -- progress from the choice of a good basis is extremely satisfying, congrats!

The #RankedChoiceVoting Act is a landmark piece of legislation that would institute RCV for all primary and general elections for the U.S. House & Senate. https://t.co/IHl46QU0RY

@zdeborova Love it! I like to cook black trumpet into a cream sauce over pasta, more so than essentially any other mushroom. They also dry (and revitalize) very well in my experience!

Apropos nothing at all, I finally got around to ordering the 2022 book Breaking Ranks, by the former president of Reed College who broke with US News in 1995. https://t.co/Zo8Weu8eGA

I haven't had a chance to read yet, but looks like @StefanWager wrote the causal inference book I've always wanted! https://t.co/8rMD4Z9vVF
