Title: Mathematical models of network archaeology

Abstract:
Large networks that change dynamically over time are ubiquitous in
various areas such as social networks,
and epidemiology. These networks are often modeled by random dynamics
which, despite being relatively simple,
give a quite accurate macroscopic description of real networks. In
«network archaeology» one studies statistical
problems of inferring the past properties of such growing networks,
given the current state of the network. In this
talk we discuss some simple network models and review recent results
on revealing the past of the networks.

Pompeu Fabra University in Barcelona. His main research interests
include statistical, learning theory, sequential prediction, nonparametric classification
and regression, random graphs, and concentration inequalities.
He has published four research monographs and over 120 papers on these topics.

In 2021, Lugosi delivered the “Breiman lecture» at NeurIPS, the prime conference on Machine Learning,
and was an invited speaker in the newly created Statistics section at the 2022 International Congress of Mathematicians.

He has also been “Medallion Lecturer” and “Blackwell lecturer” in conferences organized by the Institute of Mathematical Statistics.
