Windowed thinning and query complexity for the bouncy particle and Zigzag samplers

Jianfeng Lu, Yinchen Luo

Let $μ (d x) \propto e^{- U (x)} d x$ on $R^{d}$ , where $U$ is $m$ -strongly convex and $L$ -smooth, and denote by $κ = L / m$ the condition number. We consider windowed thinning, an exact si…

Approximating Young Measures With Deep Neural Networks

Rayehe Karimi Mahabadi, Jianfeng Lu, Hossein Salahshoor

Parametrized measures (or Young measures) enable to reformulate non-convex variational problems as convex problems at the cost of enlarging the search space from space of functions…

Error Bounds for Open Quantum Systems with Harmonic Bosonic Bath

Kaizhao Liu, Jianfeng Lu

We investigate the dependence of physical observable of open quantum systems with Bosonic bath on the bath correlation function. We provide an error estimate of the difference of p…

Riemannian Langevin Monte Carlo schemes for sampling PSD matrices with fixed rank

Tianmin Yu, Shixin Zheng, Jianfeng Lu +2

This paper introduces two explicit schemes to sample matrices from Gibbs distributions on $S_{+}^{n, p}$ , the manifold of real positive semi-definite (PSD) matrices of size $…
