CityU-CCCN-PolyU Joint Seminars

The CCCN-CityU-PolyU Joint Seminar Series began in 2001, and has since become regular weekly meetings for visitors, faculty, researchers and students to discuss latest progresses in their research. The usual venue is FYW-3316, Fong Yun Wah Building (access from Chinese Garden corridor, down the escalator on the left of the gate connecting Festival Walk) at CityU or CD-634, Core D of PolyU.

Minimal Stability-Recovery in Perturbed Markov Chains
Dr Lin Lin, The University of Hong Kong

Abstract: In this seminar, we will discuss stability-analysis and minimal-recovery problems for perturbed Markov chains, which serve as a fundamental model for autonomous systems operating under stochastic uncertainty and functional perturbations. To tackle the challenges of robustness assurance and resilience quantification, a computational framework is presented that establishes stability criteria through the spatial relation of reachable and invariant sets, introduces a robustness indicator to identify system-critical transitions, and synthesizes minimal recovery strategies to ensure system resilience. The theoretical results are demonstrated through two applications: an ultrasound navigation system that ensures reliable anatomical landmark identification, and a robotic soft tissue surgery plan that guarantees success against anatomical uncertainties.

Speaker's Bio: Dr Lin Lin is currently a Post-Doc Fellow at The University of Hong Kong and the Multi-Scale Medical Robotics Center, Hong Kong. Prior to that, she was a Post-Doc Fellow in the Department of Electrical Engineering at City University of Hong Kong. She received her Ph.D. degree in Mechanical Engineering from The University of Hong Kong in April 2024. She was a visiting research student at the University of Adelaide, King’s College London, and Hokkaido University in Oct.-Dec. 2022, May-Jul. 2023, and Feb. 2024, respectively. Her research interests include networked collective intelligence, logical networks, and reinforcement learning. Dr. Lin was a recipient of the Hong Kong Young Scientist Award (Honorable mention), IETI PhD Fellowship Award, the Outstanding Engineering Thesis Award from HKU, and Outstanding Master Degree Thesis Award from Chinese Institute of Electronics.
