The Big Data Intelligence lab at KAIST is led by Prof. Joyce Jiyoung Whang at the Department of Computer Science. The group is engaged in fundamental research on diverse aspects of big data with emphasis on developing novel computational algorithms for massive and complex data sets that arise in varied scientific and industrial applications. The group explores various data mining, machine learning, and graph mining tasks to obtain scalable algorithms for real-world data. By closely collaborating with industries such as Samsung Electronics, Naver, and SK broadband, the group formulates new problems in information retrieval and Web search, and develops new algorithms to solve these challenging problems.
