Welcome to the LearnData Lab
Machine Learning and Data Mining Research lab at SKKU
We are a dynamic research group at the Sungkyunkwan University (SKKU). Our aim is to develop Machine Learning/Data Mining models on Inter-Connected Data (e.g., human interactions, object graph in 3D, social networks, knowledge base, education log, sensor network, and multi-modal graph) and Natural Language Processing (e.g., knowledge-enhanced large language models (LLMs) and logical/symbolic reasoning). The current research topics include self-supervised graph learning, multi-modal learning (image/text or sensors), question/answering, logical reasoning, knowledge tracing, recommender systems, and explainable AI (XAI).
We are looking for passionate new Ph.D. students and Postdocs to join the team (more info) !
We are part of the College of Computing and Informatics (소프트웨어융합대학) at Sungkyunkwan University (SKKU) and affiliated with Computer Science Engineering (소프트웨어학과), Artificial Intelligence (인공지능대학원), and Intelligent Software (지능형소프트웨어) departments.
We are grateful for funding from the National Research Foundation of Korea (NRF), BK21, Information & Communications Technology Planning & Evaluation (IITP), National IT Industry Promotion Agency (NIPA), LG Electronics, NCSOFT, and NAVER.
