RAIN Lab에서는 인공지능(AI), 머신러닝(ML), 그리고 네트워크(Network)에 대한 첨단 연구를 수행합니다. 오늘날의 IT 시스템은 데이터와 함께 AI를 품는 방향으로 새롭게 설계되고 있습니다. 우리 연구실은 AI 기술과 이를 위한 Network 기술을 연구하며, 인공지능이 우리의 일상으로 스며들 수 있도록 하는 것을 목표로 합니다.
At RAIN Lab, we pursue frontier research spanning Artificial Intelligence, Machine Learning, and Networking. As modern IT systems are being reimagined to embrace AI as a native component alongside data, we develop both the intelligence itself and the networks that bring it to life. Our mission is to make AI a seamless, pervasive part of everyday life.
