Title: Exploring the Foundations and Paradigms of AI for Databases



Speaker: Professor Gao Cong, Nanyang Technological University



Abstract: 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 cover AI4DB, focusing

on the following topics:  1) Query Plan Representation as a foundation

of AI4DB, serving as input for various AI4DB tasks.  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).  3) LLMs

for Query Rewriting – A brief introduction to using large languagemodels (LLMs) in query optimization.  The talk will then briefly

explore the development of data systems to support AI applications.
