Accelerating Langevin Sampling with Birth-death
Yulong Lu, Jianfeng Lu, James Nolen
A fundamental problem in Bayesian inference and statistical machine learning is to efficiently sample from multimodal distributions. Due to metastability, multimodal distributions…
A Dimension-Free Hermite-Hadamard Inequality via Gradient Estimates for the Torsion Function
Jianfeng Lu, Stefan Steinerberger
Let be a convex domain and let be a subharmonic function, , which satisfies on the boundary .…
Moderate Deviation for Random Elliptic PDEs with Small Noise
Xiaoou Li, Jingchen Liu, Jianfeng Lu +1
Partial differential equations with random inputs have become popular models to characterize physical systems with uncertainty coming from, e.g., imprecise measurement and intrinsi…
Reactive trajectories and the transition path process
Jianfeng Lu, James Nolen
We study the trajectories of a solution to an Itô stochastic differential equation in $\Rm^d$, as the process passes between two disjoint open sets, and . These segmen…
A variational perspective on cloaking by anomalous localized resonance
Robert V. Kohn, Jianfeng Lu, Ben Schweizer +1
A body of literature has developed concerning "cloaking by anomalous localized resonance". The mathematical heart of the matter involves the behavior of a divergence-form elliptic…
