DESCRIPTION:Online social networks provide a rich substrate for informatio
 n diffusion. Everyday\, a portion of the billions posts and photos shared 
 on Facebook generates cascades of reshares\, enabling many additional peop
 le to see\, like\, comment and in turn reshare them. This data provides a 
 unique opportunity to study the way information spreads from one person to
  another.\n\nThis talk is a overview of several research projects that Fac
 ebook has been conducting to capture what virality means and imply in term
 s of social network analysis. From Obama's hug and expositions of wild rum
 ors\, to predicting the size of cascades and campaigns for a million likes
  in the hopes of getting lucky\, we will cover practical aspects of data e
 xploration\, sanitization and modeling.\n\nBio: Adrien Friggeri is a compu
 tational sociologist on Facebook’s Data Science team. His research range
 s from the abstract study of structural graph features to understanding th
 e links between psychology and network topology. After spending a few year
 s establishing a mathematical model of social communities\, his work has s
 hifted back towards dynamic processes and information diffusion on social 
 networks.\n
