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…

Trajectory-Optimized Density Control with Flow Matching
Xu Duan, Dongmei Chen
Optimal transport (OT) and Schr{ö}dinger bridge (SB) problems have emerged as powerful frameworks for transferring probability distributions with minimal cost. However, existing a…
