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

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...

Q: How are resources consumed in transportation networks, and how does this shape the overall functioning of the system?
We introduce the minimum-cost percolation framework and apply it to the U.S. air transportation system using publicly available data.

BRAN Lab is here, my first research group.
We explore how and why we connect (and disconnect), using network science, signed networks, ML, and cognitive modeling: from minds to systems, humans to AI, mental health to epidemic prevention.

Here's another paper by Shalizi showing how inferring *latent* homophily allows for disentangling from contagion. Bizarre how this gets overlooked, since it's obvious that homophily leaves huge traces in the network structure, while contagion changes nothing.

We propose a minimum-cost percolation (MCP) framework to model resource consumption in transportation networks, applied to the US air system. Encouraging cooperation among air carriers can boost the system’s robustness to disruptions!

New release! Version 0.9.5 adds support for hyperedge line width. We also fixed an error in our random generative models and made some methods up to 4x faster (!!!) in the process. @kaiserdaniel.bsky.social also made his first contribution, fixing an error in the hypergraph Laplacian. Thanks Daniel!
