Detectability threshold in weighted modular networks
We study the necessary condition to detect, by means of spectral modularity optimization, the ground-truth partition in networks generated according to the weighted planted-partition model with two eq...

When are communities detectable in weighted networks? You can find the answer in our latest preprint. Great collaboration with @filipisilva.bsky.social @skojaku.bsky.social arxiv.org/abs/2511.00214
Scale invariance and statistical significance in complex weighted networks
Most networks encountered in nature, society, and technology have weighted edges, representing the strength of the interaction/association between their vertices. Randomizing the structure of a networ...

When you randomize a weighted network, be careful! Results may depend on the unit used for the weights, particularly when you want to know if they are statistically significant. Check our paper, just out on the arXiv. @skojaku.bsky.social @filipisilva.bsky.social

Toward a Physics of Deep Learning and Brains
Deep neural networks and brains both learn and share superficial similarities: processing nodes are likened to neurons and adjustable weights are likened to modifiable synapses. But can a unified theo...

Cascades of activity in deep neural networks reveal that they learn best when they are at quasi-criticality, just like brains. Take a look at our paper, just out on the arXiv! arxiv.org/abs/2509.22649

My tribute to Alex Vespignani's 60th birthday, a celebration of his unique ability to lead large teams. How can we pot the black ball into the side pocket bypassing the obstruction of the blue and the yellow? With great team work, involving all 16 balls! www.youtube.com/watch?v=-pmg...
