Capturing many-body effects for metal ions in aqueous phase through developing specialized machine learning force fields

Madelyn Smith, Pengfei Li

Metal ion–ligand interactions govern reactivity, bioavailability, and catalytic function across chemistry and biology, yet the many-body effects underlying water exchange around multivalent metal ions remain difficult to capture with classical force fields. Ab initio molecular dy…Read more

FedSPM: Routing-Enabled Federated Learning under Dual Heterogeneity via Semiparametric Mixture

Zijian Wang, Pengfei Li, Guangyu Yang, Qiong Zhang

Routing-prediction federated learning has emerged as a new paradigm that reframes inter-client heterogeneity as a resource for system-level intelligence: at inference time, the server routes each external query to the best-matched client for prediction. Existing approaches, howev…Read more

Legible Shared Autonomy: Implicit Communication of Robot Belief through Motion

Jinwei Liu, Pengfei Li, Shaofeng Chen, Tao Wang, Yun-Bo Zhao

Shared autonomy systems combine user input with autonomous assistance to help users with motor impairments control robot arms to perform everyday manipulation tasks, by inferring user goals and providing appropriate guidance. However, the robot's internal beliefs about user goals…Read more
