Excited to share this new model by amazing grad student @IAitsahalia!

Hierarchical latent structure learning through online inference.

Bridges flat latent-cause inference and hierarchical structure, capturing multiscale abstraction.

So happy to share our newest modeling preprint with @kyo_iigaya !! https://t.co/ie7bVD1yhS

Excited to share our new preprint!

We introduce the Sparse Cognitive Graph — a computational framework for how reward biases transition structure toward compact, goal-directed graphs.

Excited to be heading to the NeurIPS workshops this weekend! If anyone is interested in chatting about opportunities at @BasisOrg or about my favorite topic of computational psychiatry, feel free to reach out!

Excited to see our NMH paper featured here for #WorldMentalHealthDay! https://t.co/ij54cQIDHK

Many psychiatric symptoms are inherently social. @XiaosiGu, @JoeBarnby, & I call for models that reflect processes most relevant to our questions, esp. for those about social symptoms

So happy to have so many smiling and joyous and relieved Palestinian children photos and videos to share. It doesn’t diminish the loss and heartbreak but it’s a blessing to witness the relief. May it only increase in the days weeks and years ahead.

🎉More belated congratulations to our faculty: Dr. @shawnrhoadsphd was promoted to Assistant Professor and launched his own lab with us, the SINC Lab. This achievement reflects his impressive scholarship and leadership in the field!

New York Rats made it to @NeurIPSConf 2025 . Work spearheaded and to be presented by @ralph_ep at a workshop on AI for non-human animal communication: https://t.co/YuPbPZiOL3 and the paper is on Open review: https://t.co/3FlSJOaqry

Want to do research on self-harm/suicide? Good, it’s a critical topic. But it’s also not one you want to “just do it,” you want to approach it thoughtfully and carefully.

This workshop (on 8/21) will help you with that if you’re interested in this area:

New preprint!

tl;dr — We ran around late at night to record wild rats in NYC and figured out how to quantify their behavior and environment. 🧵

We're launching an "AI psychiatry" team as part of interpretability efforts at Anthropic!  We'll be researching phenomena like model personas, motivations, and situational awareness, and how they lead to spooky/unhinged behaviors. We're hiring - join us! https://t.co/cUPsJ8ktsG

[Angela Radulescu @angelaradulescu.bsky.social @angelaradulescu]

Sustaining attention is hard, & people do it more if they're rewarded. Fun collab with a great group of co-authors!

"As the murder continues, what stops it from being a perfect crime is that people remain on the scene, loudly call it murder, point to the culprit, say the names of the dead, mourn them, hold vigils, and fiercely protect their rights for restitution." https://t.co/9titvQGmwX

[Kyo Iigaya @kyo_iigaya]

Thrilled to announce our lab has received the Notice of Award for our first @NIMHgov R01! 🎉

We'll be tackling anhedonia in schizophrenia using computational psychiatry. Huge thanks to our incredible lab members and collaborators🙌

[pradyumna sepulveda @pradysd]

🚨A new preprint! If you are curious about reward/punishment anticipation in psychiatry and computational mechanisms, we have something for you. Please take a look! Thanks to @kyo_iigaya @IAitsahalia Krishan and Toby, happy to be part of this team. https://t.co/oIOR2wJdxO

[Ines Aitsahalia @IAitsahalia]

Proud to share a new preprint from the lab— I am ✨anticipating✨ everyone’s feedback!
