Adaptive Reparametrized Time for Score-Based Diffusion Sampling
Yilie Huang, Wenpin Tang, Xun Yu Zhou
We study timestep allocation for score-based diffusion sampling, where a learned reverse-time dynamics is discretized on a finite grid. Uniform and hand-crafted schedules are stand…

A Zeroth-Order Deep Learning Method for Fully Nonlinear Parabolic Partial Differential Equations with Unknown Coefficients
Yanwei Jia, Du Ouyang, Huyên Pham +1
High-dimensional partial differential equations (PDEs) with unknown coefficients arise widely in scientific machine learning, including continuous-time reinforcement learning, yet…
