Professor Prakash Narayan (ECE/ISR) is the principal investigator for a three-year, $600K National Science Foundation grant for Shared Information: Theory and Applications.
The research will develop the concept of shared information as a fundamental, quantifiable, and compact measure for capturing interdependence among multiple correlated signals. It will emulate and enhance the spirit of Claude Shannon’s celebrated and enormously consequential notion of mutual information, which constitutes a measure of correlation between two random signals.
Narayan will investigate the role of shared information for operational meanings in network information theory with implications for related communication applications, and as a self-contained, compact, and calculable figure-of-merit that can be optimized in learning applications where statistical correlation is of central interest.
His goal is to establish central theoretical and practical roles for shared information in network data compression, distributed function computation, reliable and secure information transmission in networks, signal cluster detection, and a new category of statistical estimation and learning algorithms. Engineering applications include communication and signal processing in a smart home, satellite image reconstruction, and messaging protocols in automated guided vehicles and drone swarms.
