SUMMARY:Posting behavior in Social Networks and Content Active Filtering
DESCRIPTION:\n\n\nAbstract:\nIn this talk\, first we describe a model of
 the posting behavior in Social Networks in topics which have negative
 externalities\, and the second objective of it is to provide a content
 active filtering control such that the content diversity increase. By
 negative externalities\, we mean that when the quantity of posted contents
 about some topic increases the popularity of posted contents decreases. We
 introduce a dynamical model to describe the posting behavior of users
 taking into account these externalities. Our model is based on stochastic
 approximations and sufficient conditions are provided to ensure its
 convergence to a unique rest point. We provide a close form of this rest
 point. Content Active Filtering (CAF) are actions taken by the
 administrator of the Social Network in order to promote some objectives
 related to the quantity of contents posted in various topics. As objective
 of the CAF we shall consider maximizing the diversity of posted
 contents.\n\n\nBiography:\nAlexandre Reiffers is a third year PHD student
