Chaeyun Lim Profile

Hello, I'm

Chaeyun Lim

임채윤

Integrated M.S.–Ph.D. Student in Applied Artificial Intelligence

Myongji University, South Korea

Exploring the convergence of Artificial Intelligence, Wireless Networking and Extended Reality.

Research Interests

Artificial Intelligence (AI) · Wireless Networking (Wi-Fi MAC) · Extended Reality (XR)

Integrated M.S.–Ph.D. Program in Applied Artificial Intelligence @ Myongji University (DAN Lab.)

I study how learning-based methods can make wireless networks more efficient, and how those networks can better support immersive media.

  • Wi-Fi MAC & Latency Reinforcement-learning-based contention window control for IEEE 802.11bn to reduce tail latency under dynamic QoS traffic.
  • Distributed Learning over Ad Hoc Networks Communication-efficient federated learning (Baton-FL, Chain FL) for UAV and wireless ad hoc environments.
  • Immersive 3D Media ROI-aware point cloud downsampling and 3D detection for efficient transmission of XR content.
