- Reposted by Adam J. EisenIn a system subject to unobserved control, can you infer both the underlying dynamics and the control objective? 🤔 A year ago, I was presenting our work at IEEE CDC on solving this problem for stochastic LQR. arxiv.org/abs/2502.15014 Short 🧵 on the results, and how I think about them a year later.

- “I will die on the hill that population coding is the relevant level of encoding information in the brain.” In the latest “This paper changed my life,” Nancy Padilla-Coreano discusses a paper on mixed selectivity neurons. #neuroskyence www.thetransmitter.org/this-paper-c...
- Reposted by Adam J. EisenWe put out this preprint a couple months ago, but I really wanted to replicate our findings before we went to publication. At first, what we found was very confusing! But when we dug in, it revealed a fascinating neural strategy for how we switch between tasks doi.org/10.1101/2024.09.29.615736 🧵
- 🎉New project 🎉 doi.org/10.1101/2024... How do we navigate between brain states when we switch tasks? Are dynamics driven by control, or passive decay of the prev task? We shed light on this classic debate by comparing high-d linear dynamical systems fit to EEGs and RNNs during task-switching 🌀
- Reposted by Adam J. EisenReally proud of this project with @adamjeisen.bsky.social - Jacobian estimation is a challenging and generic problem in dynamics, and I’m excited for all the future use cases of our method! See you at NeurIPS 🧠💻
- 12/🙏🏻Thanks for following along. And a HUGE thanks to @neurostrow.bsky.social @sarthakc.bsky.social @leokoz8.bsky.social and my advisors @earlkmiller.bsky.social + Ila Fiete for being fantastic collaborators on this project!

- 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.🧵⬇️
- 2/ Complex systems, including 🧠 brains, 🌲 ecosystems, and 🧬 gene networks, are made of interacting parts. In the brain, different areas coordinate how they interact in different contexts. This is how our attention shifts between our senses, thoughts, and experiences.🖼️🎧💭
- 3/🎛️Control theory offers a powerful lens to understand these interactions. It describes how inputs can steer a system towards a desired goal. We present a new framework based on control theory that characterizes complex, nonlinear control directly from data.
