The first batch of tickets will be released TODAY (Aug 10) at 1pm PT (pacific time). We are fairly certain we will be able to release more later on, so if tickets run out, we will direct people to a wait list (sign up if interested)

Verify using the COLM template (and font!) to avoid silly desk rejections. Careful of copy-pasting from other venue submissions, because it often overrides our template

Very excited about @nthngdy.bsky.social's new work! It really gets to the bottom (or top, depends where the head in LMs is 😜) and fundamentals of contemporary LLMs. A real treat of a paper: solid theory, and very cool experiments.
🧵New paper: "Lost in Backpropagation: The LM Head is a Gradient Bottleneck"
The output layer of LLMs destroys 95-99% of your training signal during backpropagation, and this significantly slows down pretraining 👇

Zoe presented this paper at NeurIPS D+B: it's all knots(🪢🪢🪢!?), no language tokens were harmed (or reinforced) in the process
It's such a fun and creative paper, a real mind twist ;)
You really get to think carefully about visual intelligence looking at these knots 🪢

I am potentially recruiting a postdoctoral fellow through this program. If interested, name me as a mentor, and ping me to let me know that you are applying! The process includes some sort of interview, so I can try to squeeze a few of these in advance (it will help a lot!)
