报告摘要:

the rapid development of ai technologies expands its impact into multiple fields, including the data management domain. in this talk, we will first present our recent work in integrating ai and db technologies on the emerging topic of learned indexes. while learned indexes for one-dimensional data have been widely studied, there are relatively fewer results on learned indexes for multi-dimensional and high-dimensional data. in this talk, we will introduce new learned indexes for these two types of data, respectively. for the multi-dimensional data, we propose an index based on a learned space-filling curve, together with novel query optimization algorithms. for the high-dimensional data, we discuss two types of integrating learning into indexing and approximate k-nn query processing, including one that is optimized for external i/os and the other that predicts the parameters used for probing the index. next, we will briefly introduce the large language models (llms) and some of its impact to the data management field.
