Flow Matching vs DDPM: Why ODE Beats SDE in Diffusion Models
DDPM needs 1000 steps, Flow Matching needs 10. The mathematics of straight-line generation. Comparing SDE curved paths vs ODE straight paths.
Flow Matching vs DDPM: Why ODE Beats SDE in Diffusion Models
DDPM needs 1000 steps, Flow Matching needs 10. The mathematics of straight-line generation.
TL;DR
- DDPM: Remove noise gradually via stochastic process. Random perturbations at each step create curved paths
- Flow Matching: Move directly toward data via deterministic process. Straight paths enable fast generation
