Network Dynamics

Temporal network mining, dynamic community discovery and diffusion processes such as epidemics and opinion dynamics.

Relationships change, links are replaced, collaborations rise and fall: the systems we study are constantly evolving. Freezing a network in time helps describe it, but not to understand the dynamics that drive it.

Temporal network mining works on timestamped interactions, from social exchanges to mobility traces and financial operations. Its goal is to uncover the relations between sequences of events in order to describe and forecast how time-evolving systems behave.

Three families of problems

Individual dynamics

How local structures, nodes and edges, appear and disappear over time, as in link and node prediction.

Collective dynamics

How the mesoscale topology changes as local structures do, as in dynamic community discovery and frequent pattern mining.

Diffusion processes

How epidemics, opinions and information flow on top of static and evolving network structures.

Objectives

  1. 1

    Define novel algorithms to study dynamic network topologies.

  2. 2

    Model diffusive processes, such as epidemics and opinion dynamics, unfolding on complex topologies.

  3. 3

    Understand the feedback loops between topological dynamics and diffusive processes.
