報(bào)告摘要：Approximate nearest neighbor search is an important research topic with a wide range of applications. In this talk, we first introduce this problem and review the major research results in the past. We discuss the current work in the database research community, categorizing the work by their key underlying methodologies such as locality-sensitive hashing and approximate nearest neighbor graphs. Finally, we examine several new directions, with a focus on vector databases to support large language models.
