Sampling Using Hybrid Stochastic Dynamics
Björn Engquist, Kui Ren, Yunan Yang
This work proposes a framework for sampling from the Gibbs distribution of a given potential using hybrid stochastic dynamics. In this framework, two distinct sampling dynamics are…
Velocity Reconstruction from Flow-Induced Magnetic Fields
Yacine Mokhtari, Christina Frederick, Yunan Yang +1
We study the inverse problem of reconstructing an incompressible velocity field from observations of the induced magnetic field . In the presence o…
On the Unique Recovery of Transport Maps and Vector Fields from Finite Measure-Valued Data
Jonah Botvinick-Greenhouse, Yunan Yang
We establish guarantees for the unique recovery of vector fields and transport maps from finite measure-valued data, yielding new insights into generative models, data-driven dynam…
Sampling with Adaptive Variance for Multimodal Distributions
Björn Engquist, Kui Ren, Yunan Yang
We propose and analyze a class of adaptive sampling algorithms for multimodal distributions on a bounded domain, which share a structural resemblance to the classic overdamped Lang…
