Dr Yun Sing Koh


Dr Yun Sing Koh is a Senior Lecturer at the School of Computer Science, The University of Auckland, New Zealand. Her research is in the area of machine learning. Within the broad research realm, she is currently focusing on three strands of research: data stream mining, lifelong and transfer learning, and pattern mining. She has published more than 80 research papers in this field at top venues.  She has been active in research community including serving as the Program Co-Chair of the Australasian Data Mining Conference 2018 and as the  Workshop Chair for the 15th Pacific-Asia Conference on Knowledge Discovery and Data Mining.  She has just been awarded a Marsden Fast-Start grant in the 2018 round.
