Check out this new paper: Led by @mehdiazabou and @evadyer, we show that it is possible to get SOTA brain decoding with transfer across individuals and tasks! The key is a clever way to tokenize spiking data for transformers. #brain #neurotech #NeurIPS2023
Is a universal brain decoder possible? Can we train a decoding system that easily transfers to new individuals/tasks? Check out our #NeurIPS2023 paper where we show that it’s possible to transfer from a large pretrained model to achieve SOTA 🧠! Link: https://t.co/0Iebjpt4TM 🧵

Autoregressive language models learn to compress data by mapping sequences to high-dimensional representations and decoding one token at a time. The quality of compression, as defined by the ability to predict the next token given a prompt, progressively improves (as measured by

3/4) I’m going to maintain a reduced position at @mcgillu and @Mila_Quebec, so don’t consider me as having completely abandoned academia. (I'm lucky to be where I am...) But, I’m keen to get more time to work with a team on some bigger problems I couldn’t tackle in my own lab.

2/4) This is a big step for me, having spent my adult life in academia. But, there was no way I could pass up an opportunity to work with some of the smartest iconoclasts in the business, including @blaiseaguera himself, @dileeplearning, and many others.

It’s been a long time coming, but I’m thrilled to share my first research paper with @arna_ghosh , @ckaplanis1, @tyrell_turing, and Doina! Just accepted to NeurIPS 2024 (see u in Vancouver! 🇨🇦). This will be a longer thread—thanks for following along! https://t.co/UvG7h2LA2H 1/11

In Deep Reinforcement Learning (RL), it is a challenge to learn representations that do not exhibit catastrophic forgetting or interference in non-stationary environments. Successor Features (SFs)...

Why does #compneuro need new learning methods? ANN models are usually trained with Gradient Descent (GD), which violates biological realities like Dale’s law and log-normal weights. Here we describe a superior learning algorithm for comp neuro: Exponentiated Gradients (EG)! 1/12

For real, everyone in neuroscience and AI: Get off this site. Elon is now using this platform to mess with American democracy. No one should be here anymore. NeuroAI Bluesky is getting livelier every day. Please come join us.

A fun @a16zBioHealth podcast w/@vijaypande & @liubowen16 on AI and drug discovery covering, among other things, foundation models in biology, LLMs for small molecules, clinical trial opt, evolution and AI, and many opportunities for AI powered efficiency in drug design
"AI for drug discovery can hit at all the inefficiencies in every step of the drug design process." - @SuryaGanguli, a16z venture partner and Professor at @Stanford. Recently, Surya and @liubowen16 , a16z investment partner, joined @vijaypande to go deep on AI in Bio. The trio

What are foundation models in neuroscience? I'll be giving a talk next week to the NIH neuroscience ethics working group. I started writing a short blog post which snowballed into this 5,000 word essay

The degree of rigor by Colin (et al) to formalize what’s meant by “biologically plausible” in terms of locality (TL;DR which variables have access to which other variables) is quite impressive, and worth thinking through for anyone interested in neuro/AI.
@BellecGuill @SuryaGanguli @stanislavfort @KordingLab @hisspikeness @aran_nayebi One final thought for you, @stanislavfort, riding on @BellecGuill's: The definition of "biologically plausible" is slippery, and many papers hide big assumptions. We made a framework to enable objective comparison of learning rules vis-a-vis "locality": https://t.co/WwaBXjdbNN

It has long been argued that only humans could produce and understand language. But now, for the first time, artificial language models (LMs) achieve this feat. Here we survey the new purchase LMs...
