CANCELLED - Microscopic Evolution of Social Networks

CANCELLED - Wednesdays@NICO Seminar, Noon, January 29, 2014, Chambers Hall, Lower Level

Professor Nitesh Chawla, University of Notre Dame

Abstract
Network evolution drives not only the emergence of macroscopic scaling but also the microscopic behaviors. We consider two fundamental microscopic problems: the node's inuence evolution and the link formation prediction to identify possible dynamical origin underlying social network microscopic evolution. We have developed a novel framework for the microscopic evolution, where the mechanisms of preferential attachment and triadic closure are well balanced. I will present this framework, along with the empirical validation on two concrete problems -- node's future influence and future link formation between two nodes. I will share the possibilities of microscopic insights about social network evolution.
