Information and Intelligence Laboratory (iil) is a research group in the Department of Electrical Engineering (and affiliated with the Graduate School of Artificial Intelligence) at Pohang University of Science and Technology (POSTECH).
Our research focuses on the quantification, processing, and transmission of information and intelligence. We investigate fundamental limits, optimal designs, and principled practical implementations of information systems, leveraging and extending mathematical tools from information theory, coding theory, and optimization.
