제목 : On the Strategic Diffusion over Social Networks
초록 : A variety of models have been proposed and analyzed to understand how a new innovation (e.g., a technology, a product, or even a behavior) diffuses over a social network, where it was mainly assumed in literature that the new innovation spreads just like a kind of epidemic process. In this talk, we consider a different diffusion model---a game-based model, where each individual makes a selfish, rational choice in terms of its payoff in adopting the new innovation. We first discuss how this strategic diffusion occurs when people are either non-progressive or progressive, and then talk about how to speed up the diffusion process via appropriate seeding of some individuals with a given budget. Our analysis is made for various representative social network topologies, such as Erdos-Rényi, planted partition graphs, and power-law graphs, which we believe draws useful implications in practice. Part of this talk was and will be presented at ACM Sigmetrics 2014 and IEEE Infocom 2015.
