Topological signal processing works! :P
Check out out latest one out!

Andrea Santoro @andreasantoro.bsky.social · 29d

Latest work at #EUSIPCO25!🚀
We bring Topological Signal Processing to the brain 🧠 — showing that edge-based approaches outperform classical GSP in task decoding.

Great collab with M.Nurisso & @lordgrilo.bsky.social 🙌

And lorenzo Zaffina showing that high temporal resolution scaffolds do distinguish between emotional profiles evoked by movies better than lower-order and other hoi signatures.

Interesting take on what’s intelligence (for). @jesseba.bsky.social showing differences between how biological vs artificial systems learn and linking behavioural performance to spectral properties of neural populations. Early results but very exciting !

Cognitive tradeoff between identification and generalization: arxiv.org/abs/2506.14797

Bound by semanticity: universal laws governing the generalization-identification tradeoff

Intelligent systems must deploy internal representations that are simultaneously structured -- to support broad generalization -- and selective -- to preserve input identity. We expose a fundamental l...

The Topological Architecture of Brain Identity

Accurately identifying individuals from brain activity—functional fingerprinting—is a powerful tool for understanding individual variability and detecting brain disorders. Most current approaches rely...

This balance between redundancy and synergy, woven into each person’s unique topological scaffold, may offer a new lens on individual variability, and a powerful pathway for identifying cognitive or clinical biomarkers. 9/n
