Improving Diffusion Generative Models via Truncated Karhunen--Loève Expansion
Yumeng Ren, Yaofang Liu, Aitor Artola +3
Pretrained diffusion models exhibit a well-known training-sampling mismatch, often attributed to exposure bias and related distribution-shift effects. We provide a quantitative int…
