  • Michelle Effros - On Capacity and the Value of Communication

  • Monday, August 21, 2017 3:30 PM - 4:30 PM EDT
    Purdue University

    Abstract:
    In information theory, the capacity of a channel is defined as the rate at which that channel can reliably deliver information. This talk considers the question of how a channel's capacity relates to the impact that that channel can have on a larger network. For example, we consider whether adding a small link to a larger network can vastly increase the amount of information that the network can carry. Equivalently, we ask whether failure of a small link can do massive damage to the capacity of the network in which that link was employed. While the answers to these fundamental questions remain incompletely understood, results to date demonstrate that the capacity of a channel can vastly under-predict the value of the communication that the channel enables.
