Welcome to the Intelligent Information Processing Lab (IIPL)

The Intelligent Information Processing Lab (IIPL) at the University of Iowa investigates fundamental mathematical principles governing information systems, and provides computational solutions to designing future machine intelligence. Active research areas include high dimensional geometry, machine intelligence, and signal processing. Our lab enjoys close collaborations with theoretical and experimental investigators.

The lab is led by Dr. Weiyu Xu
