Title: Dynamics and Evolution in Graphs and Networks

Jian Pei
Simon Fraser University

Abstract: In many scenarios, graphs and networks only capture the (often static) “infrastructure” of applications. What really interesting is the dynamics, that is, the activities on such graphs and networks. Take influential maximization as an example, a well recognized core problem in many applications like viral marketing. In many contexts, such as personalized viral marketing, cold-start recommender systems, time-sensitive message spreading in social media (e.g., WeChat and Whatsapp), the influence spreading dynamics are of critical business values. At the same time, in many contexts the problem remains unsolved and challenging. In this talk, I will review some of our latest development in investigating dynamics and evolution in graphs and networks. I will present in detail a general continuous influence maximization model, and also briefly highlight an activity maximized influence maximization model and an online influence node monitoring approach.
