CompleNet 2012

This week I’m heading out to CompleNet 2012 in Melbourne Florida. It looks like a great conference with Laszlo Barabasi, Robert Bonneau  & Sinan Aral headlining.

The conference will also feature an unreasonably high level of activity by yours truly with duties including an invited talk (8:40 on March 8th), chairing a technical session (on network metrics and models, 10:20 on March 7th), as well as a brief talk at the opening of the art exhibition on The Art of Networks at the local Foosaner Art Museum, about the creation of the TwitterMood visualization.

Hope to see you there if you’re in or around the Sunshine State!

Renaud Lambiotte

Renaud Lambiotte is visiting for a few days. He’s an exciting guy whose work focuses on the relation between dynamics, function and structure in complex systems, with a focus on neuronal and social networks (check his website for more details). He’s an associate professor in Mathematics at the University of Namur (Belgium).

If you’re in the Copenhagen area, I highly recommend going to his talk this friday. Here are the details.

Title: Random Walks on Networks: Dynamics and Teleportation

Abstract:  In this talk, I will focus on two problems related to random walks on networks. First, I will focus on random teleportation, which is a necessary evil for ranking and clustering directed networks based on random walks. Teleportation enables ergodic solutions, but the solutions must necessarily depend on the exact implementation and parametrization of the teleportation. For example, in the commonly used PageRank algorithm, the teleportation rate must trade off a heavily biased solution with a uniform solution. Here we show that teleportation to links rather than nodes enables a much smoother trade-off and effectively more robust results, and discuss the effect of teleportation on clustering. In the second part of my talk, I will focus on random walks on temporal networks, i.e. networks evolving in time. In particular, I will examine the effects of inter-event statistics on the dynamics of edges, and apply the concept of a generalized master equation to the study of continuous-time random walks on networks.
