Abstract

We consider a model of contagion where each non-seed is assumed to adopt an action if and only if the proportion of its adopting neighbors is no less than its adoption threshold. We then examine two measures for a seed set: (1) the contagion probability, defined as the probability of full contagion when the adoption threshold of each non-seed is drawn independently and uniformly at random, and (2) the contagion threshold, which is the probability of full contagion when all non-seeds share a common adoption threshold that is chosen uniformly at random. In this talk, I will highlight how the two measures are shaped by different network structures. This is a joint work with Kwa Kiam Heong.
