Collective Behavior in Online Social Networks, Politicians, and Cows

Speaker: Mason Porter, Professor, Department of Mathematics, UCLA

Host: Van Savage, Department of Ecology and Evolutionary Biology, UCLA

Complex systems of interacting entities exhibit “emergent” dynamics in the form of collective behavior. Such behavior, which can take many forms (e.g., flocking, herding, and opinion consensus), occurs in many real and model systems, even though they are not encoded in the microscopic rules of those systems.

In this talk, Porter will give an introduction to collective behavior, in both model-drive and data-driven studies, with a discussion of three examples: installing applications in online social networks, voting on bills by U.S. legislators, and synchronization of cows.

Light refreshments will be served.
