New in @pnas.org: doi.org/10.1073/pnas...
We study how humans explore a 61-state environment with a stochastic region that mimics a “noisy-TV.”
Results: Participants keep exploring the stochastic part even when it’s unhelpful, and novelty-seeking best explains this behavior.

we think this is a proposal for an alternative mechanism for phenomena that have been explained through e.g. asymmetric learning rates, and fits well with the (RL and working memory) literature, curious for feedback!
work with @becketebs.bsky.social
this funny little result is an extension to our "Imperfect Memory Programs" paper where we propose a principled way to get "value" fingerprints without ever calculating value -- through a stochastic memory that trades off precision and complexity!
Our new paper "Noisy memory generates value in changing environments" just got published in Adaptive Behavior! doi.org/10.1177/1059...
tldr: we find that stochastic encoding of outcomes can perform better than perfect encoding (woot?), esp. if you have asymmetric encoding (for reward vs no reward)
The idea that self-censoring is a new form of oppression forced on white men rather than a normal part of having a prefrontal cortex and existing in society is some of the biggest bullshit in the centrist/right wing coalition gender grift
Cracked the code for good coffee at conferences #rldm2025 @rldmdublin2025.bsky.social
Cool heated exchange. Looks like social media sometimes shows the true, dark side of people (if you missed it you missed it I guess). Otherwise the exchange is interesting, and it’s always cool to see disciplines engaging.
And it looks like Canada will keep being Canada, the good and bad, but more importantly, we will not live in the dark timeline.
It's really hard to overstate how hugely favored conservatives were up until two months ago.
Here's the graph of Canadian polling between March 2023 and March 2025. (Reminder: blue is conservative.)
Those are months and months of 20+ point leads for Tories.
Our workshop at RLDM on intrinsic motivation is still accepting abstracts for lightning talks - two weeks left to submit! More info on our website: sites.google.com/view/pimbaa2...
Come join us in Dublin! 🤩

🚨 RLDM Workshop alert! 🚨
You are coming to @rldmdublin2025.bsky.social in Dublin this summer? Come to our fun, surprising, novel, information-seeking workshop on intrinsic motivations in biology and AI! We have an amazing lineup of speakers! Visit our website: sites.google.com/view/pimbaa2...
Beyond Mechanism—Extending Our Concepts of Causation in Neuroscience onlinelibrary.wiley.com/doi/10.1111/... - really pleased that this paper with Henry Potter is now published in the European Journal of Neuroscience 😊
Lately my 3yo falls asleep caressing my arm and head and I don’t know what I did to deserve this but boy life is simple and beautiful sometimes
Oh yeah, that is on my soon to-read pile! Hope you enjoy and tell us how it went!

🚨 Inviting all Curious Agents 🔍👀 to attend our workshop @rldmdublin2025.bsky.social!!
With amazing speakers from across disciplines, we attempt to arrive at the core principles underlying intrinsic motivations in biological and artificial agents 🎮🧠🤖💪

Sometimes I do feel like wind power in Taiwan, and now I know why
It’s quite a funny and pleasant idea to think that our president knows what a Lagrangian is.
Every time I see science in the US slowly (and rapidly) declining, I try to think how in Mexico we have a president that is a woman, a physicist, a former PI in sustainable energies and development. It helps.
I’ve slowly grown fond of Connections, anyone else here plays it? Yesterday was fun
That being said I’ve wondered before if RL contains active inference, and I don’t know if anyone has explored that, curious if you find more references in that direction!
And when I say they I mean the “new” “sophisticated inference” where Friston et al. realize the power of Bellman equation
I think that this is a good reference to see how they’re basically the same objectives direct.mit.edu/neco/article...
