Noise-Space Reward Alignment for Few-Step Generative Models

Woocheol Shin, Taeyoung Yun, Jiwon Sung +7

Few-step generative models produce high-quality samples in one or a few evaluations. However, steering them toward desired properties remains difficult, especially when only black-…

Diffusion Drafts, AR Verifies: Accelerating Document OCR with Self-Speculative Decoding

Dohyun Kim, Sungjun Han, Hyungguk Kim +4

Autoregressive OCR vision-language models accurately convert document images into text and structured markup, but require one sequential decoding step per output token, limiting in…

Direct Diffusion Score Preference Optimization via Stepwise Contrastive Policy-Pair Supervision

Dohyun Kim, Seungwoo Lyu, Seung Wook Kim +1

Diffusion models have achieved impressive results in generative tasks such as text-to-image synthesis, yet they often struggle to fully align outputs with nuanced user intent and m…

Random Conditioning with Distillation for Data-Efficient Diffusion Model Compression

Dohyun Kim, Sehwan Park, Geonhee Han +2

Diffusion models generate high-quality images through progressive denoising but are computationally intensive due to large model sizes and repeated sampling. Knowledge distillation…
