SDE vs ODE: Mathematical Foundations of Score-based Diffusion
Stochastic vs Deterministic. A deep dive into Score-based SDEs and Probability Flow ODEs, the theoretical foundations of DDPM and DDIM.
SDE vs ODE: Mathematical Foundations of Score-based Diffusion
Stochastic vs Deterministic. Same distribution, different paths.
TL;DR
- SDE (Stochastic DE): Probabilistic paths with noise, theoretical basis of DDPM
- ODE (Ordinary DE): Deterministic paths, basis of DDIM and Flow Matching
