A dream come true! I presented "No Representation, No Trust" on my favorite RL podcast, TalkRL!
Make sure to check it out to learn why training with PPO for too long makes your agent collapse!

🚀 Introducing PICLe: a framework for in-context named-entity detection (NED) using pseudo-annotated demonstrations.
🎯 No human labeling needed—yet it outperforms few-shot learning with human annotations!

Here's Veo 2, the latest version of our video generation model, as well as a substantial upgrade for Imagen 3 🧑‍🍳🚢

(Did I mention we are hiring on the Generative Media team, btw 👀)

lol. yes, very true and important
the crucial first step in fighting anthropomorphization of DL systems is to find an easier to write and pronounce word than anthropomorphizing.

I am in Vancouver for NeurIPS 2024 until December 16th if you want to meet, DM or email me.
We have two accepted papers from my lab:
1. Building on Efficient Foundations: Effective Training of LLMs with Structured Feedforward Layers, on Wednesday, East Exhibit Hall A-C #2010 (1/3)

favorite conference experience for me :)
The Uncertainty in Artificial Intelligence conference (UAI) is on 🦋!

I'm a bit biased, but this is a fantastic conference for #probabilisticML, #causality, #causalML, #tractable #probabilistic #models, #imprecise probabilities,
#reasoning, #neurosymbolic approaches and more.

#causalSky #statSky
We are the premier conference on #uncertainty in #AI and #ML since 1985 🧓

Hello, 🦋!

Follow us to reduce uncertainty!

Better VQ-VAEs with this one weird rotation trick!

I missed this when it came out, but I love papers like this: a simple change to an already powerful technique, that significantly improves results without introducing complexity or hyperparameters.

I've put together a starter pack of EPFL researchers across all labs and domains! 🇨🇭 Would love to expand this list and showcase more amazing work happening at EPFL. Drop a reply to be added!
