Title: Stochastic and Multi-Objective Optimization in AI: Theory, Algorithms, and Applications
 
Abs:
This tutorial presents recent advances in stochastic optimization and multi-objective optimization for modern AI systems. The tutorial is structured in two parts. In the first part, we explore stochastic optimization problems involving AI through the lens of Stochastic Gradient Langevin Dynamics (SGLD). In particular, we discuss its theoretical foundations, examine its applications to multi-period, multi-asset portfolio optimization, and introduce new research directions.  In the second part, we present a novel optimization framework, Dual Cone Gradient Descent (DCGD). We discuss its theoretical properties and demonstrate its applicability to real-world problems such as Physics-Informed Neural Networks (PINNs) and machine unlearning.
 
Bio: 
Dong-Young Lim is an assistant professor in the Department of Industrial Engineering and the Artificial Intelligence Graduate School at UNIST. He received his B.S., M.S., and Ph.D. degrees in Industrial and Systems Engineering from KAIST, where his doctoral research focused on financial engineering and mathematical finance. He later joined the School of Mathematics at the University of Edinburgh as a Marie Sklodowska-Curie Fellow, conducting research on learning theory in AI. From June to August 2024, he was a visiting researcher in the Optimization Theory Group at the Alan Turing Institute in the UK. His research interests include stochastic analysis, stochastic differential equations (SDEs), and stochastic and multi-objective optimization, with applications in AI and operations research/management science.

Title: From Classical to Recent Advances in Sufficient Dimension Reduction
 
Abs:
This talk provides a comprehensive overview of Sufficient Dimension Reduction (SDR), beginning with classical methods such as Sliced Inverse Regression (SIR) and Sliced Average Variance Estimation (SAVE). It expands to nonlinear extensions, including methods that leverage neural networks to approximate complex regression structures. The discussion further extends SDR principles into functional data contexts, addressing the challenges posed by infinite-dimensional data and introducing functional SIR and GSIR (Generalized SIR). Finally, the tutorial connects SDR methods to graphical models, presenting how dimension reduction can be integrated into graphical models.

Title: Advances in On-Device AI: Methods and Applications
 
Abs:
The rapid advancement and widespread adoption of AI—especially deep learning technologies—in resource-constrained environments have driven a growing demand for on-device AI across a wide range of platforms, including mobile devices, IoT nodes, robots, and autonomous vehicles. This tutorial presents a set of innovative strategies and applications, which makes on-device AI possible for intelligent tasks once considered infeasible, such as Sora-style text-to-video generation.

Title: Text-to-Video Retrieval
 
Abs:
With the rapid rise of video-sharing platforms such as YouTube, massive amounts of content are produced and uploaded daily, expanding information retrieval beyond traditional web search to include video data. This tutorial presents techniques for retrieving videos via natural language queries: first, we introduce partially relevant video retrieval methods that identify videos containing one or more segments related to a text query; next, we discuss video moment retrieval, which localizes the precise temporal interval within a single video that best matches the query; and finally, we address key challenges, particularly scalability in large-scale video search, focusing on memory footprint and inference speed.
