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 is centered around the quantification and transmission of information and intelligence. We aim to find fundamental limits, optimal designs, and principled practical implementations of information systems, often by pushing mathematical tools from information theory, coding theory, (convex) optimization, and learning theory in new directions.
