CFG: Control Classifier-Free Guidance via Score Discrepancy Analysis
Jiayang Gao, Tianyi Zheng, Jiayang Zou +9
Classifier-Free Guidance (CFG) is a cornerstone of modern conditional diffusion models, yet its reliance on the fixed or heuristic dynamic guidance weight is predominantly empirica…

Visual Text Compression as Measure Transport
Lv Tang, Tianyi Zheng, Yang Liu +2
Visual text compression (VTC) promises efficient long-context processing by rendering text into an image and re-encoding it with a vision-language model, often producing --$20\t…

Pruning for Sparse Diffusion Models based on Gradient Flow
Ben Wan, Tianyi Zheng, Zhaoyu Chen +2
Diffusion Models (DMs) have impressive capabilities among generation models, but are limited to slower inference speeds and higher computational costs. Previous works utilize one-s…
