Our #AI #DynamicalSystems #FoundationModel DynaMix was accepted to #NeurIPS2025 with outstanding reviews (6555) – first model which can *zero-shot*, w/o any fine-tuning, forecast the *long-term statistics* of time series provided a context. Test it on #HuggingFace: huggingface.co/spaces/Durst...

We have openings for several fully-funded positions (PhD & PostDoc) at the intersection of AI/ML, dynamical systems, and neuroscience within a BMFTR-funded Neuro-AI consortium, at Heidelberg University & Central Institute of Mental Health: www.einzigartigwir.de/en/job-offer... More info below ...

Is it possible to go from spikes to rates without averaging? We show how to exactly map recurrent spiking networks into recurrent rate networks, with the same number of neurons. No temporal or spatial averaging needed! Presented at Gatsby Neural Dynamics Workshop, London.

Today I joined >1900 members of US National Academies of Science, Engineering & Medicine signing this open letter (views our own). Leadership of science by US has been paramount for >70yrs & Admin is now acting to throw it all away! docs.google.com/document/d/1... www.nytimes.com/2025/03/31/s...

What a fantastic accomplishment -- and what a fantastic story! www.quantamagazine.org/at-17-hannah...

Got prov. approval for 2 major grants in Neuro-AI & Dynamical Systems Reconstruction, on learning & inference in non-stationary environments, out-of-domain generalization, and DS foundation models. To all AI/math/DS enthusiasts: Expect job announcements (PhD/PostDoc) soon! Feel free to get in touch.

We wrote a little #NeuroAI piece about in-context learning & neural dynamics vs. continual learning & plasticity, both mechanisms to flexibly adapt to changing environments: arxiv.org/abs/2507.02103 We relate this to non-stationary rule learning tasks with rapid performance jumps. Feedback welcome!

Happy to discuss our work on parsimonious & math. tractable RNNs for dynamical systems reconstruction next week at cns2025florence.sched.com/event/1z9Mt/...

How do animals learn new rules? By systematically testing diff. behavioral strategies, guided by selective attn. to rule-relevant cues: rdcu.be/etlRV Akin to in-context learning in AI, strategy selection depends on the animals' "training set" (prior experience), with similar repr. in rats & humans.

What a line up!! With Lorenzo Gaetano Amato, Demian Battaglia, @durstewitzlab.bsky.social, @engeltatiana.bsky.social,‪ @seanfw.bsky.social‬, Matthieu Gilson, Maurizio Mattia, @leonardopollina.bsky.social‬, Sara Solla.

Into population dynamics? Coming to #CNS2025 but not quite ready to head home? Come join us! at the Symposium on "Neural Population Dynamics and Latent Representations"! 🧠 📆 July 10th 📍 Scuola Superiore Sant’Anna, Pisa (and online) 👉 Free registration: neurobridge-tne.github.io #compneuro

I’m really looking so much forward to this! In wonderful Pisa!

Just heading back from a fantastic workshop on neural dynamics at Gatsby/ London, organized by Tatiana Engel, Bruno Averbeck, & Peter Latham. Enjoyed seeing so many old friends, Memming Park, Carlos Brody, Wulfram Gerstner, Nicolas Brunel & many others … Discussed our recent DS foundation models …

Can time series (TS) #FoundationModels (FM) like Chronos zero-shot generalize to unseen #DynamicalSystems (DS)? No, they cannot! But *DynaMix* can, the first TS/DS FM based on principles of DS reconstruction, capturing the long-term evolution of out-of-domain DS: arxiv.org/pdf/2505.131... (1/6)

I'm presenting our lab's work on *learning generative dynamical systems models from multi-modal and multi-subject data* in the world-wide theoretical neurosci seminar Wed 23rd, 11am ET: www.wwtns.online --> incl. recent work on building foundation models for #dynamical-systems reconstruction #AI 🧪

My latest post is now out. I show how Trump's attacks on science and universities are neither random nor new - they fit very precisely into the authoritarian playbook. This means we can guess what might come next and prepare - and we must! christinapagel.substack.com/p/censor-pur...

Our revised #iclr2025 paper and codebase for an architecture for foundation models for dynamical systems reconstruction is now online: openreview.net/pdf?id=Vp2OA... ... includes additional examples of how this may be harvested for identifying drivers (control par.) of non-stationary processes.

Toward interpretable #AI foundation models for #DynamicalSystems reconstruction: Our paper on transfer & few-shot learning for dynamical systems just got accepted for #ICLR2025 ! Previous version: arxiv.org/pdf/2410.04814; strongly updated version will be available soon ... (1/4)

That paper discusses an important issue for RNNs as used in neurosci. But we would argue that many RNN approaches do not truly reconstruct DS, for which we demand also agreement in long-term stats, attractor geometry, and generative perform. (esp. in chaotic systems, MSE as stats can be misleading).

Great to see this group on Bluesky. Durstewitz and Seamans 2008 is one of my all time favorite papers on the function of dopamine in the PFC www.researchgate.net/profile/Dani...

Now may be a good time to introduce our group on bsky with some of our contrib. to dynamical systems reconstruction (DSR) from past year. By DSR we mean learning a *generative surrogate model* of a dyn. process from TS data which reproduces full attractor & generalizes to new init. conditions (1/6)

Good targets for foundation/ inference models/ LLMs …

Can really recommend this excellent talk by Christoph Bergmeir at neurips.cc/virtual/2024... yesterday … on the inability of Transformer- & LLM-based recent time series models to beat even simple baselines *if you do the stats and testing right*! A lesson in careful stat. eval.

Don't miss out on our 2 @neuripsconf.bsky.social papers on dynamical systems reconstruction today & tomorrow: 1) neurips.cc/virtual/2024...

Happy our team is among this years’ recipients of the Samsung Global Research Outreach Awards! www.sait.samsung.co.kr/saithome/abo... We will take #DynamicalSystems reconstruction to the next level, large-scale – looking forward to the collaboration with the Samsung team!

And with a bit of delay now also here: 📢 New work on hippocampal assemblies & theta! www.nature.com/articles/s41... It was a pleasure to work with Nadine Becker, Aleks Domanski, Timothy Howe, Kipp Freud, @durstewitzlab.bsky.social, Matt Jones. @SantAnna Pisa @Bristol Neuro @ZI Mannheim 🧵[1/11]
