Working on mathematical foundations/probabilistic interpretability of ML (what NNs learn🤷‍♂️, disentanglement🤔, king-man+woman=queen?👌…)
Pinned
Machine learning has made incredible breakthroughs, but our theoretical understanding lags behind.

We take a step towards unravelling its mystery by explaining why the phenomenon of disentanglement arises in generative latent variable models.

How do tokens evolve as they are processed by a deep Transformer?

With José A. Carrillo, @gabrielpeyre.bsky.social and @pierreablin.bsky.social, we tackle this in our new preprint: A Unified Perspective on the Dynamics of Deep Transformers arxiv.org/abs/2501.18322

ML and PDE lovers, check it out!

If few-shot transfer is ur thing!
We maintain strong zero-shot transfer of CLIP / SigLIP across model size and data scale, while achieving up to 4x few-shot sample efficiency and up to +16% performance gains!

Fun project with @confusezius.bsky.social, @zeynepakata.bsky.social, @dimadamen.bsky.social and
@olivierhenaff.bsky.social.
🤔 Can you turn your vision-language model from a great zero-shot model into a great-at-any-shot generalist?

Turns out you can, and here is how: arxiv.org/abs/2411.15099

Really excited to this work on multimodal pretraining for my first bluesky entry!

🧵 A short and hopefully informative thread:

Just wondering (very neutrally!)… if authors have to review as a condition of submitting themselves, but they then review in *clear bad faith*, should their own submissions be rejected as if they had not reviewed? 🤔

The Country Land and Business Association says the new £1m cap on agricultural inheritance tax relief will "harm 70,000 farms". That's 1/3 of all farms.

What does the actual data show? Less than 500 farms/year will be pay more tax as a result of this change every year. Possibly as few as 100.
