All researchers should fight against this. Every week I try to persuade my students that top papers often have few quantitative results. With work that's new, important, and clearly qualitatively different (zero to one!), you don't need quantitative results. Demos not tables!

Iโ€™m excited to share a project Iโ€™ve been working on for over a year, which I believe will fundamentally change our approach to language models. Weโ€™ve designed a new architecture, which replaces the hidden state of an RNN with a machine learning model. This model compresses

Happy to share the latest version of our work on compositional cognitive maps in hippocampus, with Jo Warren, @jrcwhittington, Tim Behrens. We propose hippocampus constructs maps from cortical building blocks in replay โ€“ now with empirical support! nature.com/articles/s4159โ€ฆ 1/9

My favorite figure from our new Circuits papers -- "How does Claude do math?" Claude simultaneously does: 1. a back of the envelope calculation of the tens digits -- "the answer should be somewhere around 90". 2. an exact calculation of 6+9=15 using these super cool look up

A nice paper illustrating how far away modern AI and neuromorphic computing is from the type of learning actually seen in the brain

Honored to share a major thread of my PhD research, out now in PNAS. We address a core issue with how models are used for scientific discovery. Models are so important that they define the entire scientific process... 1/n

Excited to share work on using classical search approaches to scale inference in diffusion models! We show how global graph search algorithms (BFS, DFS) and local search can be used to improve generation performance across domains such as image generation, planning, and RL!

I am weirdly obsessed with closest point query algorithms in physics, geometry and recently ML applications On GPU you care about memory access and data locality, so you want spatial neighbors to be close in 1D index space. Same is desired for attention mechanics, because you
