I’m happy to share our new paper, “KerJEPA: Kernel Discrepancies for Euclidean Self-Supervised Learning”: arxiv.org/abs/2512.19605 This work builds on the LeJEPA framework by reinterpreting its regularization objective through the lens of kernel discrepancies.

In 1965, Margaret Dayhoff published the Atlas of Protein Sequence and Structure, which collated the 65 proteins whose amino acid sequences were then known. Inspired by that Atlas, today we are releasing the Dayhoff Atlas of protein sequence data and protein language models.
So you want to skip our thinning proofs—but you’d still like our out-of-the-box attention speedups? I’ll be presenting the Thinformer at two ICML workshop posters tomorrow! Catch me at Es-FoMo (1-2:30, East hall A) and at LCFM (10:45-11:30 & 3:30-4:30, West 202-204)
Annabelle Michael Carrell@ab-carrell.bsky.social · last yr.Your data is low-rank, so stop wasting compute! In our new paper on low-rank thinning, we share one weird trick to speed up Transformer inference, SGD training, and hypothesis testing at scale. Come by ICML poster W-1012 Tuesday at 4:30!

Low-Rank Thinning
The goal in thinning is to summarize a dataset using a small set of representative points. Remarkably, sub-Gaussian thinning algorithms like Kernel Halving and Compress can match the quality of unifor...

I've been shocked that a theory-driven method yields practical results this good, especially on attention approximation. I proposed my best new optimizer design originally as a dumb baseline; the fact that you can get these efficiency gains with a principled approach makes me a lil insecure.
