We are the Data+AI Group at Nanyang Technological University (NTU). Our research focuses on Data management and AI, bridging the gap between data management and artificial intelligence. We explore two main directions: DB4AI (Database for AI) and AI4DB (AI for Database). Our research includes learned index, learned query optimization and data generation. Our projects are supported by grants awarded by Ministry of Education, NRF, IAF, Singtel/NCS, Roll-Royce, Alibaba, and Microsoft.
