AATRN Networks seminar, June 3 at 5pm CET by Carles Casacuberta

[Daniela]

Dear AATRN Networks members,

Our next online seminar will be Tuesday, June 3, at 5pm CET / 11am Eastern Time.

Speaker: Carles Casacuberta

Title: A chordless cycle filtration scheme in topological data analysis for complex network dimensionality detection.

Abstract: Many complex networks, ranging from social to biological systems, exhibit structural patterns consistent with an underlying hyperbolic geometry. The dimensionality of this latent space is surprisingly low for most real-world networks. We introduce a novel topological data analysis weighting scheme for graphs, based on chordless cycles, aimed to estimate the dimensionality of complex networks in a data-driven way. We further show that the resulting descriptors can effectively estimate network dimensionality using a neural network architecture trained on a synthetic graph database constructed for this purpose. This is joint work with Aina Ferrà, Robert Jankowski, Meritxell Vila, and Mariàngels Serrano.

We will meet in the following coordinates:
