2010-11 Program on Complex Networks Opening Tutorials & Workshop
Workshop Information
General Information
The Opening Workshop for the SAMSI program on Complex Networks was held on Sunday-Wednesday, August 29-September 1, 2010, at the Radisson RTP in Research Triangle Park, NC.
On Sunday, August 29, tutorials were presented. From Monday to Wednesday, invited speakers gave presentations. There was a poster session and reception on Monday, August 30. Immediately following the workshop, on Thursday and Friday, research working groups convened for initial meetings at SAMSI.
The workshop focused on five complementary themes at the forefront of current research in complex networks, incorporating perspectives ranging from theory to applications, in disciplines spanning applied mathematics, computer science, probability, statistics, and statistical mechanics. The five focus areas are as follows.
(1) Network Sampling and Inference: Theory and methods relating to the sampling of network data and the corresponding inference of network characteristics, including applications to tasks like community detection and estimating the size of 'hard-to-count' populations.
(2) Dynamic Networks: Modeling and inference of networks in the context of dynamical systems evolving in time, such as time-varying gene regulatory interactions or email social networks.
(3) Percolation and Diffusion on Networks: Theory regarding the behavior of phenomena like social contact processes and epidemics on networks.
(4) Spectral Analysis and Geometric Algorithms: Topics in network analysis integrating aspects of spectral graph theory and algorithms based on geometric embeddings.
(5) Biological Applications of Networks: Various applications of network-based approaches to biological problems, such as in the context of cell biology or the epidemic spread of disease.
The workshop culminated in the formation of research working groups on the afternoon of Wednesday, September 1. These working groups met individually at SAMSI on Thursday and Friday to further address specific research objectives to be addressed by the working group over the ensuing year. These meetings also established modes of cooperation for the working groups, via web or teleconference, to facilitate full participation of all members, regardless of residence status at SAMSI.
Organizers: Eric Kolaczyk (Boston University), Michael Mahoney (Stanford), Peter Mucha (UNC), Rick Durrett (Duke)
