IISL@HYU

Information and Intelligence Systems Lab (IISL) is a research group in the Department of Electronic Engineering at Hanyang University, affiliated with the Graduate School of Artificial Intelligence Semiconductor. Our research spans artificial intelligence, optimizations, statistical inference, information theory, with a broad range of applications in modern engineering systems. Core topics include (but are not limited to) faster learning for hyperscale AI, distributed learning, reinforcement learning, AI for wireless communications, large-scale optimization, and statistical signal processing.

Opening

We are actively looking for motivated graduate students who are interested in machine learning, reinforcement learning, wireless communications, or optimizations.
- Openings for AI Algorithms/Optimizations and Reinforcement Learning in the Graduate School of Artificial Intelligence Semiconductor (인공지능반도체 대학원)
- Openings for Machine Learning (Continual Learning/Federated Learning/Many-Task Learning) and 6G Communications in the Department of Electronic Engineering (BK21, Beyond-G Global Innovation Center)
