Entropic Analysis of Time Evolving Networks

Dept. of Computer Science (March 8, 2018)

SEMINAR SERIES : Distinguished Lecture

MAJOR SPEAKER : Hancock, Edwin R.
LENGTH : 75 min.
ACCESS : Open to all
SUMMARY : This talk focuses on how to use network entropy as a means of characterising network structure and investigating the relationship between changes in network structure and function with time. Examples are presented on network data extracted from the data for the New York Stock Exchange. We show how the entropic characterisation can be extended to develop Euler- Lagrange equations which describe the evolution of the node degree distribution, and can be used to predict the evolution of network structure with time. If time permits, we will also describe how to extend our model to include quantum spin statistics, and explore how Bose-Einstein and Fermi-Dirac statistics modify the evolution of network structure. We demonstrate some of the utility of the proposed methods on fMRI images of Alzheimer brains.  [Go to the full record in the library's catalogue]
