Botany and Big Data

In many scientific disciplines, new technologies are enabling researchers to obtain measurements of unprecedented scale and resolution. These huge data sets present many new challenges and opportunities for the experimental scientists generating the data and for researchers like those in the SILO community developing data analyses. In this talk, three …

Communication, sensing and control in large scale wireless networks

Modern wireless technology enables the vision of future large scale systems such as the SmartGrid, a network of ubiquitous and heterogeneous devices wirelessly connected to the Internet, and wireless health monitoring and health modifying sensor networks over communities and not just individuals. All of these applications necessitate methods that simultaneously …

Complex Networks and Inference

Complex networks and information seeks to understand mathematically how fundamental approaches to information exchange influence overall network and system performance and behavior. From this understanding we wish to develop strategies to assess and influence the predictability and performance of heterogeneous types of networks and information systems that must provide reliable …

On the interaction between network coding and the physical layer – information theoretic results and a case study

The question of how and whether to join physical layer and network coding remains actively investigated. In this talk, we present some recent information-theoretic results and an application illustrating a view of this question. We begin by considering whether there are benefits, in capacity, from integrating network and physical layer …

Solving Symmetric Integer Programs

We will discuss two mechanisms for dealing with integer programs that contain a great deal of symmetry—orbital branching and isomorphism pruning. These methods use information encoded in the symmetry group of the integer program to guide the branching decision and prune nodes of the search tree. Orbital branching and isomorphism …
