Seminar by Federico Battiston: Structure and dynamics of multiplex networks

Federico Battiston from Queen Mary, University of London will talk about: Title: Structure and dynamics of multiplex networks Abstract: Many real-world complex systems consist of a set of elementary units connected by relationships of different kinds. All such systems are better described in terms of multiplex networks, where the links at each layer represent a …

Seminar by Dr. Gerardo Iñiguez: Modelling complex contagion with tie heterogeneities

Dr. Gerardo Iñiguez from Institute for Research in Applied Mathematics and Systems, National Autonomous University of Mexico. He is going to talk about: Modelling complex contagion with tie heterogeneities Social influence, the effect that the past behaviour of acquaintances has on our daily decisions, is arguably the main driving mechanism of many complex collective phenomena …

Seminar: The power of local search for clustering by Vincent Viallat Cohen Addad

Abstract : What are the performance guarantees of the algorithms used in practice for clustering problems? In a paper with Phil Klein and Claire Mathieu, we give the first polynomial-time approximation schemes for the following problems: (1) uniform facility location in edge-weighted planar graphs; (2) $k$-median and $k$-means in edge-weighted planar graphs; (3) $k$-means in …
