Information and Intelligence Systems Lab (IISL) is a research group in the Department of Electronic Engineering (and affiliated with the Graduate School of Aritificial Intelligence Semiconductor) at Hanyang University. Our research focuses on machine learning, optimizations, statistical inference, information theory and a broad range of applications. Core topics include (but are not limited to) faster learning for hyperscale AI, distributed learning, reinforcement learning, AI for wireless communications/circuit design, large-scale optimization and statistical signal processing.
Opening
We are actively looking for motivated graduate students who are interested in machine/deep learning, 6G communications, reinforcement learning, or large-scale optimizations.
