报告摘要：With the convergence of data and AI, the database community has actively explored two key directions: leveraging AI to tackle challenges in database systems (AI4DB) and developing data systems to support AI applications. This talk will first the following topics for AI4DB:  1) Query Plan Representation as a foundation of AI4DB, 2) Paradigms of AI4DB – We discuss “Replacement,’ aiming to learn machine learning (ML) models to replace traditional components (e.g., learned indexes), and “Enhancement,” aiming to apply ML to improve existing database components (e.g., optimizing indexes without replacement), and 3) LLMs for Query Rewriting.  The talk will then briefly cover the following topics for DB4AI:  Hybrid Vector Indexes and semantic data analytics.
