Disentanglement is an intriguing phenomenon that arises in generative latent variable models for reasons that are not fully understood. If you’re interested in learning why, I highly recommend giving Carl’s blog a read!

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. Blog post: carl-allen.github.io/theory/2024/...

Our big_vision codebase is really good! And it's *the* reference for ViT, SigLIP, PaliGemma, JetFormer, ... including fine-tuning them. However, it's criminally undocumented. I tried using it outside Google to fine-tune PaliGemma and SigLIP on GPUs, and wrote a tutorial: lb.eyer.be/a/bv_tuto.html

I think this comes down to the model behind p(x,y). If features of x cause y, e.g. aspects of a website (x) -> clicks (y); age/health -> disease, then p(y|x) is a (regression) fn of x. But if x|y is a distrib'n of different y's (e.g. cats) then p(y|x) is given by Bayes rule (squint at softmax).

Read our paper: Context-Aware Multimodal Pretraining Now on ArXiv Can you turn vision-language models into strong any-shot models? Go beyond zero-shot performance in SigLixP (x for context) Read @confusezius.bsky.social thread below… And follow Karsten … a rising star!

🤔 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:

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.
