My memory sucks. Note-taking is my superpower. I decided to upgrade this superpower by making a living knowledge base for research, powered by Claude Code (or any context agent). Here's a github template so you can do the same too. 🧵 github.com/ilennaj/obsidian-scientist-knowledge-template

Steve is an engineering VP at Microsoft and I find a similar pattern is showing up for product managers. I see lots of PMs who were already good now multiplying their impact with AI while weaker PMs are now using AI to generate work slop which is a waste of everyone’s time.

Thrilled to start 2026 as faculty in Psych & CS @ualberta.bsky.social + Amii.ca Fellow! 🥳 Recruiting students to develop theories of cognition in natural & artificial systems 🤖💭🧠. Find me at #NeurIPS2025 workshops (speaking coginterp.github.io/neurips2025 & organising @dataonbrainmind.bsky.social)

#NeurIPS2025 workshops are underway! Today’s workshop presentations from the #KempnerInstitute cover a range topics, including the use of #AI in linguistics and the study of communication & sensing in electric fish. #NeuroAI

Different seeds with same training loss doesn't always mean same solution. When do neural nets converge vs diverge? What are the implications for inverse problems, #AI4Science & #MechInterp? #NeurIPS2025 poster 2001 (“a space odyssey”), 4:30–7:30pm today 12/5:

Celebrating the Rajan Lab’s papers at #NeurIPS2025! Stop by to chat with these talented students and postdocs 🎉

33 neuroscience researchers from across the world shared how their labs our funded, providing insight into the current state of funding and how that might shift. By @claudia-lopez.bsky.social #neuroskyence #StateOfNeuroscience www.thetransmitter.org/funding/whic...

How do brain areas control each other? 🧠🎛️ ✨In our NeurIPS 2025 Spotlight paper, we introduce a data-driven framework to answer this question using deep learning, nonlinear control, and differential geometry.🧵⬇️

Looking forward to sharing our work at #NeurIPS2025 next week! Session 6 on Fri 12/5 at 4:30-7:30pm, Poster 2001 ("a space odyssey") Details on this thread by the brilliant lead author @annhuang42.bsky.social below:

Controversial take: our ICLR reviews actually helped make our paper better

Our next paper on comparing dynamical systems (with special interest to artificial and biological neural networks) is out!! Joint work with @annhuang42.bsky.social , as well as @satpreetsingh.bsky.social , @leokoz8.bsky.social , Ila Fiete, and @kanakarajanphd.bsky.social : arxiv.org/pdf/2510.25943

new paper with @robertchisciure.bsky.social link.springer.com/article/10.1... "Cognition all the way down 2.0: neuroscience beyond neurons in the diverse intelligence era" 🧪

Excited to release our new work: Petri Dish Neural Cellular Automata! pub.sakana.ai/pdnca We investigate how multi-agent NCAs can develop into artificial life 🦠 exhibiting complex, emergent behaviors like cyclic dynamics, territorial defense, and spontaneous cooperation.

In case you don't know already, the journal Open Mind has a Bluesky account that automatically posts new papers: @openmindjournal.bsky.social The journal is diamond open access (free to read, free to publish) thanks to the support of MIT Press, Harvard Library, & MIT Library.

Excited to announce that my first postdoc paper is now online! Links: www.nature.com/articles/s41... rdcu.be/eAcN7 In it, we examine the perennial question: what changes in the brain when learning a new motor skill? Read more below to find out 👇

Excited to share a new project spanning cognitive science and AI where we develop a novel deep reinforcement learning model---Multitask Preplay---that explains how people generalize to new tasks that were previously accessible but unpursued.

For the past 3 years, I've taught a course on Machine Learning for Climate Change to undergrads. At times, people have asked if the course lectures could be made available online. While I can't offer that, I have decided to start making "5 Minute Papers on AI for the Planet" videos. Hope its useful!

If you're at #RLDM2025, check out our contributed talk at Session 3 (Fri 6/13, 12:10pm), presented by my brilliant co-first-author on this project @sjohnsonyu.bsky.social! Wasn't able to make it in person, but would love to hear your thoughts @kempnerinstitute.bsky.social @harvardmed.bsky.social

Check out our new work on making robots process touch more like brains! Surprisingly, ConvRNNs best matched mouse cortex—passing the NeuroAI Turing Test. We also developed tactile-specific SSL augmentations and an Encoder-Attender-Decoder framework unifying ConvRNNs, SSMs & Transformers.

It was an honor to speak at the @kempnerinstitute.bsky.social on how some of our recent works can be interpreted as an application of rational analysis to language model behaviors — seeing both their successes and failures through the lens of adaptation to the properties of their training data.

After using electrical stimulation to activate their muscles, patients improved movement in their paralyzed limbs even when the system was turned off. The team leading the clinical trial believes new nerve connections may have begun to grow. https://cbsn.ws/43ocCrA

Big day for the Rajan lab at @harvardmed.bsky.social Friday Seminar Series 🌟 @satpreetsingh.bsky.social & Siyan Zhou gave outstanding talks on collective behaviors in artificial fish schools & disordered attractors in mice. I’m so proud of their work! 🤖🧠

📽️Recordings from our @cosynemeeting.bsky.social #COSYNE2025 workshop on “Agent-Based Models in Neuroscience: Complex Planning, Embodiment, and Beyond" are now online: neuro-agent-models.github.io 🧠🤖

ML/stats folks! This might be a stupid question but my brain isn’t working. In control theory, is there a way to directly infer a system’s objective function by just observing its behavior (as opposed to doing model comparison hypothesis tests)?

At @cosynemeeting.bsky.social ? Don't miss the workshop "It's All Connected" or how graph neural networks help us understand the structure-function relationship in the brain🧠 Thanks to the organizers @neurokim.bsky.social @briandepasquale.bsky.social Sam Lewallen 🌟 sites.google.com/bu.edu/gnnwo...
