1/2) Please let's all remember that GWT is a theoy of access consciousness (what is available for verbal reasoning) and not phenomenal consciousness (subjective experience): philpapers.org/rec/BLOOAC Obviously, in this study access consciousness is literally what they test in the LLMs. #NeuroAI 🧪

The way AI-antis talk about "The Bubble Popping" is starting to sound like the way that QAnon people talk about "The Storm": an overwhelming event of such magnitude that it becomes impossible for anyone to deny that "they were right." It's a myth of emotional catharsis and unambiguous validation.

I basically agree with this, with one amendment: the problem isn’t that there isn’t any incentive for smart people to get into politics, but ther there isn’t any incentive to think about things. In our populist moment, the truth is always already known, the correct policy has already been decided.

Compromising in the culture war by saying "her schlong" whenever one might otherwise have said "her penis". It may be crude but this is how we can live together in a liberal democracy.

This is a sound take. Also you almost surely do not sufficiently hate the media

My paper modelling and simulating meditative deconstruction via letting go is now out open access in Neural Computation at @mitpress.bsky.social 🧠 I show how the phenomenology of experiential deconstruction (defabrication) naturally emerges from the dynamics of hierarchical active inference. 🧵

I am the last true Free Speech Warrior in that I basically hate Hasan Piker and Cenk Uygur but don't think they should have been banned from coming to the UK. Same re Kanye West. These people are valueless simpletons who make our culture and country worse with every utterance, but so it goes.

this place is like a time capsule

Our work with Karl Friston on Self-Orthogonalizing Attractor Neural Networks is now out in Neurocomputing! What does this theoretical model mean for our understanding of the brain? I’ve mapped out the key neuroscience implications below. Read the thread for a neuroscience walk-through ↓

Attractor dynamics are a hallmark of brain function. But are they just epiphenomena? Starting from the free energy principle, we show that attractors can actually implement Bayesian priors in self-organizing networks, linking local neural dynamics directly to macro-scale probabilistic inference.

old man yells at claude

Sanjeev Namjoshi's textbook "Fundamentals of Active Inference" provides a comprehensive, up-to-date introduction to active inference and the free energy principle for an engineering-focused audience: mitpress.mit.edu/978026205095...

What is the brain for? Active inference is widely discussed as a unifying framework for understanding brain function, yet its empirical status remains debated. Our review identifies core predictions across the action-perception cycle and evaluates their empirical support: osf.io/preprints/ps...

I really think at its heart philosophy is one giant battle, taking place over many eras and nations, between people who are basically pleasant bureaucrats and people who are sexy murder poets, and it’s both super important and super boring that the pleasant bureaucrats must win.

I am frustrated by the anti-AI obsession on this place. I understand people are annoyed by AI being imposed on us for trivial things and by the AI uber alles discourse but it really feels like older people complaining about a new technology.

As many of you know, I’ve been fascinated by brain attractor dynamics lately. Thrilled to share a new preprint on their link to orthogonal neural representations, co-authored with Karl Friston: arxiv.org/abs/2505.22749 - with implications for both neuroscience & AI! First in a series - stay tuned!

In episode 1000, I talk with Dr. Karl Friston about the Free Energy Principle and active inference, from #Physics to mind. #CognitiveScience #Science youtu.be/2BzmKnDtCCI

Honored to speak at Ottawa about how Canada can lead in #NeuroAI. With world-class talent, trusted institutions, & sustainable infrastructure, we can build a federated approach to AI that protects mental health & strengthens our society. Thanks @braincanada.bsky.social for the invitation!

Elegant theoretical derivations are exclusive to physics. Right?? Wrong! In a new preprint, we: ✅ "Derive" a spiking recurrent network from variational principles ✅ Show it does amazing things like out-of-distribution generalization 👉[1/n]🧵 w/ co-lead Dekel Galor & PI @jcbyts.bsky.social 🧠🤖🧠📈

Preprint time: “Shannon invariants: A scalable approach to information decomposition” arxiv.org/abs/2504.15779 Studying information in complex systems is challenging due to difficulties in defining multivariate metrics and ensuring their scalability. This framework addressed both challenges!

Computational theory is about computers (i.e. "technology") in the same way that astronomy is about telescopes. Thinking that computation is not fundamentally important for biology because "a cell is not like a laptop" is to miss the forest for the trees. N/N

Reinforcement Learning and Active Inference are two frameworks used in computational psychiatry, but these are rarely directly compared empirically. In this new article, we aimed to compare these in a more systematic manner by fitting each to multiple datasets: papers.ssrn.com/sol3/papers....

It's not just that just about everything I've ever published is in this particular database and used without my permission. It's that everything I've ever published was used without my permission to develop such a shitty, flawed and fundamentally useless tool. I deserve compensation for THAT itself.

Bluesky has become awesome and I am absolutely loving it.

hello world model

Big sigh. The FEP is just the principle of maximum entropy or maximum caliber, under the constraint that boundaries exist. Every now and then, people who do not understand the FEP opine about it loudly and uncharitably. This is yet another case in point. Skill issue!
