VLM-in-the-Loop: A Plug-In Quality Assurance Module for ECG Digitization Pipelines

Jiachen Li, Shihao Li, Soovadeep Bakshi +2

ECG digitization could unlock billions of archived clinical records, yet existing methods collapse on real-world images despite strong benchmark numbers. We introduce \textbf{VLM-i…

DM-MPPI: Datamodel for Efficient and Safe Model Path Integral Control

Jiachen Li, Xu Duan, Shihao Li +2

We extend the Datamodels framework from supervised learning to Model Predictive Path Integral (MPPI) control. Whereas Datamodels estimate sample influence via regression on a fixed…

Datamodel-Based Data Selection for Nonlinear Data-Enabled Predictive Control

Jiachen Li, Shihao Li, Jiamin Xu +2

Data-Enabled Predictive Control (DeePC) has emerged as a powerful framework for controlling unknown systems directly from input-output data. For nonlinear systems, recent work has…

Influence Functions for Data Attribution in Linear System Identification and LQR Control

Jiachen Li, Shihao Li, Soovadeep Bakshi +2

When a controller is designed from an identified model, its performance ultimately depends on the trajectories used for identification, but pinpointing which ones help or hurt rema…

Auction-Based Task Allocation with Energy-Conscientious Trajectory Optimization for AMR Fleets

Jiachen Li, Soovadeep Bakshi, Jian Chu +2

This paper presents a hierarchical two-stage framework for multi-robot task allocation and trajectory optimization in asymmetric task spaces: (1) a sequential auction allocates tas…

IF-CPS: Influence Functions for Cyber-Physical Systems -- A Unified Framework for Diagnosis, Curation, and Safety Attribution

Jiachen Li, Shihao Li, Soovadeep Bakshi +2

Neural network controllers trained via behavior cloning are increasingly deployed in cyber-physical systems (CPS), yet practitioners lack tools to trace controller failures back to…
