Periodic reminder that what really identifies a Bayesian is their fondness for integrating out uncertainty, i.e. marginalization, not wedging things into Bayes theorem. Even Fisher did that from time to time.

Behold the future of research code from the GPT-6 press release: a notebook that writes an accessory script by string concatenation and inspecting code in a notebook, evals the script in place, and then ignores it entirely to write a hardcoded summary.
an ad-hoc "save data" script in a jupyter notebook that constructs a python module by constructing a string from a literal, catting the inspected source from live functions to it, calling eval, and then writing that out to a separate script? despite the fact that.... we are in a jupyter notebook??? and we can just.... write python??? and run it???

Summary of the Project
This project explores how the brain constructs perceptual experience from visual input, focusing on the role of Bayesian models in perception. A key challenge in vision science is understanding how humans interpret complex scenes from the limited information available in retinal images. Modern theories suggest that perception involves probabilistic inference, where the brain integrates sensory signals with prior expectations to make sense of the world. However, the origins and nature of these expectations remain poorly understood. This research aims to advance our understanding of perceptual experience by examining how structured patterns in visual input can inform models of perception. The work spans computational modelling and experimental approaches to uncover principles that explain how visual systems interpret properties such as shape, material, and lighting from images. By addressing fundamental questions about perception, this project will contribute to psychology, neuroscience, and artificial intelligence, offering insights into how biological and artificial systems can learn to interpret complex environments.

Why is touch perceived as weaker during movement? In our new preprint 📝, we examine tactile suppression during reaching. Using optimal control theory, we show that tactile suppression reflects dynamic, uncertainty-dependent integration of forward model predictions and sensory feedback.

My goodness.
Sam Altman tweet:

Tonight, we reached an agreement with the Department of War to deploy our models in their classified network.

In all of our interactions, the DoW displayed a deep respect for safety and a desire to partner to achieve the best possible outcome.

AI safety and wide distribution of benefits are the core of our mission. Two of our most important safety principles are prohibitions on domestic mass surveillance and human responsibility for the use of force, including for autonomous weapon systems.  The DoW agrees with these principles, reflects them in law and policy, and we put them into our agreement.

We also will build technical safeguards to ensure our models behave as they should, which the DoW also wanted. We will deploy FDEs to help with our models and to ensure their safety, we will deploy on cloud networks only.

We are asking the DoW to offer these same terms to all AI companies, which in our opinion we think everyone should be willing to accept. We have expressed our strong desire to see things de-escalate away from legal and governmental actions and towards reasonable agreements.

We remain committed to serve all of humanity as best we can. The world is a complicated, messy, and sometimes dangerous place.
