AI today follows the scaling paradigm: more data + more compute = better model. This works in controlled settings but breaks down in the unpredictable real worlds robots operate in.
We need adaptive intelligence for physical AI. Tim talks about it here: https://t.co/T0pFp0ZBYm
pymdp 1.0.0 is here: batched, autodifferentiable, JIT-compiled active inference in JAX: https://t.co/Hhzsh1wOv5
This release brings:
GPU/TPU-ready active inference
autodiff through inference, planning and learning
easy parallelization and batching with vmap()
Great report by @avaskham on evolution of reward prediction error theory of dopamine. Balanced perspectives. Wish it covered dopamine's role in reducing uncertainty (re: rewards, navigation, etc), which accounts of "rethink[ing of] what the brain cares about reinforcing."
The neuroscience field is grappling with whether to modify the long-standing theory of reward prediction error—or abandon it entirely.

Thanks so much for your research and your presence! Full house.
thanks @oxford, thanks Prof. Friston!
Thanks organizers :) / and sponsors!
I'm speechless.
Not peer-reviewed yet but a submitted paper.
The 'presented images' were shown to a group of humans. The 'reconstructed images' were the result of an fMRI output to Stable Diffusion.
In other words, #stablediffusion literally read people's minds.

New paper in Science today on playing the classic negotiation game "Diplomacy" at a human level, by connecting language models with strategic reasoning! Our agent engages in intense and lengthy dialogues to persuade other players to follow its plans. This was really hard! 1/5

Check out our new paper, to appear at NeurIPS. We show that DNNs are becoming progressively *less* aligned with human perception as their ImageNet accuracy increases. Ignore the elections, Elon, and FTX for a moment — this is important!

@speakerjohnash@MattPirkowski@algekalipso@gnomicperfect Good question. Prediction errors are unsigned divergences between predictions and outcomes: one can be more or less wrong, but that doesn't track goodness or badness per se. But we've argued hierarchical active inference models can account for valence:

Yesterday was my last day of working at Google. Perhaps this comes as surprise to you twitter folks, as I haven't widely announced that I left academia to try something new. Here's what I learned in 9 months as a Data Analyst who (temporarily) left Astronomy for Big Tech. 1/n
