Résumé
DDPM is the original stochastic recipe; DDIM is a faster, deterministic shortcut that produces comparable images in far fewer steps.

What is DDPM and DDIM Samplers?
DDPM ak DDIM ñaari anam lañu yu ñuy jaar ngir doxal xeetu diffusion bi, ñuy soppi bruit bu bari ci nataal jéego par jéego. DDPM mooy rëset stokastik bi njëkk; DDIM ab gaawaay bu gëna gaaw la, muy defar ay nataal yu nuróo ci jéego yu néew.
Lan mooy njariñ li gëna mag ci DDIM ci kaw DDPM?
DDIM dafa topp yoon wu deterministik, wu amul Markovian, loolu moo koy may mu teggi jéego yu bari ci jamono, defar nataal yu baax ci diggante 10 ba 50 jéego, du téemeeri jéego.
