Freshly out: "A Novel Model for Novelty: Modeling the Emergence of Innovation from Cumulative Culture" link.springer.com/chapter/10… — Kudos to Natalie Kastel for her first work with the @PPSP_Team! —She will soon start a PhD with us, exploring Social #NeuroAI in Multiagent Systems 🚀

Ever wondered how many symptoms make up all of adult psychopathology described in the DSM-5? It’s 628! How many do you think repeat across multiple diagnoses? If you answered 231 symptoms repeating a total of 1022 times (median 3 times per symptom, range 2-22), good job! 🧵

Reward-is-enough assumes that every ancillary feature of intelligence operates *in the service of* reward-maximization. No! Reward is a theoretical stopgap to generate behavior when you can't explain why something is valuable. Creative justification is often the impetus to act.

I don't think Reward Is Enough, and I explained why and what to do about it to the lovely @InferenceActive institute, check it out! Many people started following me bc of a paper I put out called Reward is Not Necessary, this is a partial summary of it. youtube.com/watch?v=Fh1e4sKh…

Our new preprint is now on arxiv. I hope this paper can help students and researchers in cognitive robotics to learn WMs and FEP. :) >[2301.05832] World Models and Predictive Coding for Cognitive and Developmental Robotics: Frontiers and Challenges arxiv.org/abs/2301.05832

What great prospects by @BorsboomDenny! An interesting conjunction with our article just accepted (coming soon!) after 2 years of work, to make this idea concrete: we propose the (first) model of a psychiatric disorder based on dynamic systems (like in meteorology 🌥️) ⬇️

Systematic review of prediction models in psychiatry finds that nearly all are at risk for bias, and only 20% do external validation. Only a single 1 out of 228 investigated formal assessment for clinical utility. nature.com/articles/s41380-0…

What are your neuroAI paper highlights for this year? Am preparing an end-of-year state-of-the-field post

Find a way to make the less charitable interpretation of what I am saying "ok"
PAPER ALERT 🎺 In our new paper - just out in Synthese - we tackle a long-standing question whether PP is actually testable. If you’re interested in our take, see a short thread below: link.springer.com/article/10… (1/9) 🧵

work in progress; trying to make it simple and tight. This is a skeleton of how my thinking went, when trying to formulate positions on various X's.
