Out today in Nature Machine Intelligence! From childhood on, people can create novel, playful, and creative goals. Models have yet to capture this ability. We propose a new way to represent goals and report a model that can generate human-like goals in a playful setting... 1/N

'Inside Out' got Core Memories wrong in that they had anything to do with content or importance. Kids randomly pick 1 of every 1000 experiences as Core, that's how you end up with stuff like: "remember when we want to Paris for a week?" "no...oohh yeah, the little toy car at the Duty Free, aww!"

Oh yeah? Check this out [I take you by the hand and lead you through the streets of London. The sun does not shine. You do not change your mind. It's not clear what move I was trying to do]

really interesting stuff on diversity-of-thought vs alignment by Sonia Murthy and Jenn Hu (and I'm there too) at #NAACL2025. See also this nifty write-up at Kempner's blog here: kempnerinstitute.harvard.edu/research/dee...

i was trying to find a silly video i vaguely recalled about 'can't have too much snow', instead I got this AI explanation about why, in fact, you can have too much snow.

"points to consider"

Suppose you generated a sequence of 100 random numbers. Then one year later, you did it again. Do you think we could predict one sequence from the other? It turns out, we can! Now in press @ JEP:G with @samiyousif.bsky.social @actlab.bsky.social @robbrutledge.bsky.social; osf.io/preprints/ps...

"Did you know some universities forced students to pass Latin exams well into 1960?" "Haha that's crazy man anyway I gotta go this journal won't let us publish unless we convert our manuscript into Word so that's my afternoon gone"

inside you there are two philosophers

ah good, my special delivery of broken glass is here (I ordered a measuring cup)

flashes of the everyday in this 1902 book on the origin of proverbs. For a brief moment the curtain behind the orator is lifted, and we see a small girl roughing up a big, patient dog
