Multiscale Supervised Unbalanced Optimal Transport Flow Matching
Qiangwei Peng, Lezhi Chen, Peijie Zhou
Unbalanced optimal transport (UOT) provides a principled framework for modeling single-cell transitions and birth-death dynamics, but its high computational cost limits scalability…
WFR-FM: Simulation-Free Dynamic Unbalanced Optimal Transport
Qiangwei Peng, Zihan Wang, Junda Ying +5
The Wasserstein-Fisher-Rao (WFR) metric extends dynamic optimal transport (OT) by coupling displacement with change of mass, providing a principled geometry for modeling unbalanced…
WFR-MFM: One-Step Inference for Dynamic Unbalanced Optimal Transport
Xinyu Wang, Ruoyu Wang, Qiangwei Peng +2
Reconstructing dynamical evolution from limited observations is a fundamental challenge in single-cell biology, where dynamic unbalanced optimal transport provides a principled fra…
Integrating Dynamical Systems Modeling with Spatiotemporal scRNA-seq Data Analysis
Zhenyi Zhang, Yuhao Sun, Qiangwei Peng +2
Understanding the dynamic nature of biological systems is fundamental to deciphering cellular behavior, developmental processes, and disease progression. Single-cell RNA sequencing…
