I finally had the time to revise my website with updated descriptions of my research goals and lab activity: www.nichele.eu

Feedback is welcome 😄

PS. Is it clear enough that I *DO NOT* focus on artificial intelligence applications? 🧠

Nice article on Neural Cellular Automata!

It also talks about our work on ARC-NCA!

Quanta Magazine @quantamagazine.bsky.social · 29d

The cells of your body follow simple rules and play off one another to form a complete organism. The researcher Alexander Mordvintsev has developed “neural cellular automata,” building blocks that can self-assemble into any form. @georgemusser.com reports: www.quantamagazine.org/self-assembl...

Self-Assembly Gets Automated in Reverse of ‘Game of Life’ | Quanta Magazine

In cellular automata, simple rules create elaborate structures. Now researchers can start with the structures and reverse-engineer the rules.

Check out our new work on Critical Neural Cellular Automata 👇

sidneypontesfilho.bsky.social @sidneypontesfilho.bsky.social · Aug 5

The critical NCA got perfect score in the 5-bit memory task and can surpass the performance of the best elementary CA, rule 30, in the MNIST classification.

This work was done together with @stenichele.bsky.social and @mikkellepperod.bsky.social

Stefano Nichele @stenichele.bsky.social · Aug 4

In parallel, cellular automata and synthetic worlds show how memory and constraints can support functional behavior in minimal systems. Together, these findings are reshaping classical notions of agency, belief, and goal-directedness.

I've finally got a copy of Nils Barricelli's 1st paper on Artificial Life, in Italian (1954). Would be great to get it translated into English. My preference would be to have this done by a skilled human translator rather than AI. Any bilingual Italian-English folk out there who might be interested?

Your brain doesn’t just passively track time ⏳ - it structures it.
In @Science.org we show that activity in 🧠 memory circuits (LEC) drifts constantly, but makes sharp jumps at key moments, segmenting life into meaningful events. (1/2)

Event structure sculpts neural population dynamics in the lateral entorhinal cortex

Our experience of the world is a continuous stream of events that must be segmented and organized at multiple timescales. The neural mechanisms underlying this process remain unknown. In this work, we...

We use encoders-decoders to simulate elementary CA & identify a rich hierarchy of relationships not known before. We show that the number of elementary automata with unique dynamics can be reduced from 88 to 52!
