A long time coming, now out in Nature Machine Intelligence (@NatMachIntell): "Visual representations in the human brain are aligned with large language models." Check it out (and come chat with us about it at CCN).

We managed to integrate brain scans into LLMs for interactive brain reading and more. I think this is a big deal. Check out Vicky's post below for details. Super excited about this one!

Introducing CorText: a framework that fuses brain data directly into a large language model, allowing for interactive neural readout using natural language. tl;dr: you can now chat with a brain scan đź§ đź’¬ 1/n

This is going to revolutionize education 📚 Google just launched "Learn Your Way" that basically takes whatever boring chapter you're supposed to read and rebuilds it around stuff you actually give a damn about. Like if you're into basketball and have to learn Newton's laws,

Hi, we will have three NeuroAI postdoc openings (3 years each) to work with Sebastian Musslick (@smusslick), Pascal Nieters and myself on task-switching, replay, and visual information routing. Reach out if you are interested in any of the above, I'll be at CCN next week!

Hey @Shutterstock, We recently purchased 200,000 API credits (about 2,000 euros) for your 3D Generative API service ( https://t.co/8NuaAahLDX). The service has been down for nearly a month. Any plans on when you will bring this back online? Thanks!

Exciting new preprint from the lab: “Adopting a human developmental visual diet yields robust, shape-based AI vision”. A most wonderful case where brain inspiration massively improved AI solutions. Work with @lu_zejin @martisamuser and Radoslaw Cichy https://t.co/XVYqQPjoTA

Despite years of research and the dramatic scaling of artificial intelligence (AI) systems, a striking misalignment between artificial and human vision persists. Contrary to humans, AI heavily...

#AI and #computervision folks: this will be interesting to you! Robust visual inference beyond scale, but achieved by taking inspiration from how infant vision develops. Shown to work across many architectures and comes with a neat preprocessing pipeline that you can use.
