📍Excited to share that our paper was selected as a Spotlight at #NeurIPS2025!
arxiv.org/pdf/2410.03972
It started from a question I kept running into:
When do RNNs trained on the same task converge/diverge in their solutions?

Excited to release our new work: Petri Dish Neural Cellular Automata!
pub.sakana.ai/pdnca
We investigate how multi-agent NCAs can develop into artificial life 🦠 exhibiting complex, emergent behaviors like cyclic dynamics, territorial defense, and spontaneous cooperation.

Introducing Petri Dish Neural Cellular Automata (PD-NCA)
pub.sakana.ai/pdnca/
In this work we explore the role of continual adaptation in artificial life, where the cellular automata in our system do not rely on a fixed set of parameters, but rather learn continuously during the simulation itself.

Manuel Brenner and I managed to organize this workshop not knowing we were gonna end up being new neighbors this month. The lineup speaks for itself.
There were some last minute cancellations so we jumped in to fill their big shoes and will talk about the future directions of the new labs too!
