Great article. BPT is an absolute classic, one of my all-time favourites.

I’ve always cut them slack for focusing on behaviour, just because that’s what was readily measurable at the time.

But it goes all the down!

InputDSA: Demixing then comparing recurrent and externally driven dynamics in complex systems - Kempner Institute We explored how to measure the similarity between two complex systems when they are driven by external inputs, like biological neural circuits or reinforcement learning agents. Our novel method, calle...

NEW from the #KempnerInstitute: InputDSA, a tool to separate intrinsic dynamics from input-driven effects—enabling accurate, efficient comparisons of complex systems with external inputs.

Looks sick. You’ve been on a roll lately!

No! Swear I was taught like-urt.

I am totally pumped about this new work . "Task-trained RNNs" are a powerful and influential framework in neuroscience, but have lacked a firm theoretical footing. This work provides one, and makes direct contact with the classical theory of random RNNs:

Optimally claims aside, I genuinely love this study.

Recently, van der Stigchel and colleagues posted a provocative commentary suggesting that we should be wary of bots in online behavioral data collection (🧵by @cstrauch.bsky.social here: bsky.app/profile/cstr...). But should we? Here is my response letter osf.io/preprints/ps.... 1/5

I find AR to be very strong, but probably depends on the task.

Great thread! Missed that their indices aren’t convergent, and agree that there should be better outlier stats (eg GESD). Think they’d argue for a mixture of bots, but you’re right that for many tasks any bot would be v hard.

With Eugene Koonin, we propose a concept of “the selfish ribosome”, under which evolution of life is viewed as a ribosomal takeover, where the ribosome evolved to consume most of the cell’s resources, while other cellular componentry ensures the propagation of the ribosome. arxiv.org/abs/2602.23268

IMO:
- vscode with copilot and/or claude code
- work in bite-sized chunks
- use tests to reality-check

We have a paper, led by @ericwbridgeford.bsky.social:
