Title: Cooperative Information Exchange over Networks Tom Courtade, UCLA
Abstract: The explosion of data networks over the previous two decades has created many challenges in terms of data storage and network communications. In this talk, we discuss the problem of optimal information exchange when data is distributed over a network. In particular, we study the minimum number of communications required to achieve universal recovery, that is, for all nodes in the network to recover all data initially distributed across the network. This problem has applications in the areas of distributed storage and peer-to-peer networks, among others. If time permits, I will discuss some recent work on one-helper problems.
