Predicting influence in social networks

What are mechanisms that determine how humans influence each other in social networks? Can we predict who will react in an input signal to the network and through which connections? Those questions are studied in the paper Structured prediction of network response, co-authored by HIIT researchers Hongyu Su, Aristides Gionis, and Juho Rousu, which was presented in ICML 2014.
