ART for Diffusion Sampling: Continuous-Time Control and Actor-Critic Learning

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 standard choices, but they rely on fixed prescriptions and can therefore be suboptimal. To address this l…Read more
