Major new system and result from the team: SOAR is an open-source self-improving genAI system pushing the frontier of ARC performances using program synthesis

It relies on using LLMs as self-improving smart operators for evolutionary search

Julien Pourcel @jul-p.bsky.social · Jul 10

Introducing SOAR 🚀, a self-improving framework for prog synth that alternates between search and learning (accepted to #ICML!)

It brings LLMs from just a few percent on ARC-AGI-1 up to 52%

We’re releasing the finetuned LLMs, a dataset of 5M generated programs and the code.

Congratulations @jul-p.bsky.social for this major achievement and @ccolas.bsky.social for the amazing co-supervision ! Your work was magic to develop this self-improving system pushing the frontier of what can be done with program synthesis and open-source methods and models on the ARC challenge !

Le travail de Samuel Bianchini à partir des algorithmes de @pyoudeyer.bsky.social mis en lumière par le Jeu de paume dans son expo IA

Catalogue de l’expo « Le monde selon l’IA »

Artiste et enseignant-chercheur, Samuel Bianchini collabore avec de nombreux ingénieurs et scientifiques pour explorer les relations qu'entretiennent les nouvelles technologies avec les contextes culturels dans lesquels elles s'insèrent.
Dans cette troisième version de l'installation Prendre vie(s), Samuel Bianchini mobilise Flow Lenia, un logiciel de vie artificielle augmentee par IA. Cette forme d'animation, née d'une simulation mathématique appelée «jeu de la vie » en 1970, compose des systèmes susceptibles d'adopter des comportements émergents et inattendus.

Humans' ability to invent their own games & goals is at the core of open-ended learning.

Understanding and modeling computationally how they do it would be enlightening to understand better human cognition and build open-ended AI

Great step in this direction in new paper by Guy Davidson et al.

Nikita Lisitsa @lisyarus.bsky.social · May 6

Published my WebGPU Particle Life simulation online! Obviously it requires WebGPU support, and it's quite resource-demanding, so I've set the particle count to 64k for now. Also it probably doesn't work on mobile; will fix later.

Here is a cool Flow-Lenia simulation, which is a continuous cellular automaton with two distinct features:
1. Mass conservation - sum of all activations is constant through time
2. Localized update rules - enables simulations with differently behaving matter on the same grid

Generative AI is a cultural transmission technology:
it plays a growing role in generation, selection and transmission of ideas/opinions in human society 🧠🔄🌐

And yet we understand very little of this dynamics at this point 🤔❓

A step forward is our #ICLR2025 paper !👇

I have to say that when Nicolas pitched us the idea of this project, I was excited about the creativity, but was not convinced it would work: I was completely wrong, it worked close to directly! Beautiful!

Pierre-Yves Oudeyer @pyoudeyer.bsky.social · Apr 24

Imagine you can compute a (very) cheap behavioural signatures for LLMs and from it
1) infer their history (which previous models they derived from)
2) build large maps to navigate spaces of 100s of models
3) predict (coarsely) their performances in benchmarks

That's PhyloLM 🚀

Nicolas Yax @nicolasyax.bsky.social · Apr 24

🔥Our paper PhyloLM got accepted at ICLR 2025 !🔥
In this work we show how easy it can be to infer relationship between LLMs by constructing trees and to predict their performances and behavior at a very low cost with @stepalminteri.bsky.social and @pyoudeyer.bsky.social ! Here is a brief recap ⬇️

Forcing Diffuse Distributions out of Language Models

"When LLMs are used for real-world tasks where diversity of outputs is crucial their inability to produce
diffuse distributions over valid choices is a major hurdle"
