New math framework for reflected diffusion models

Researchers have developed new mathematical frameworks for understanding reflected diffusion processes within bounded domains. The work focuses on continuity equations and Lagrangian flows, providing conditions for these flows to remain within the domain and accurately represent density changes. The findings offer a rigorous basis for ODE-based sampling in reflected diffusion models and highlight potential failure points for such samplers. AI
