MAMBO-G: Magnitude-Aware Mitigation for Boosted Guidance

ICML 2026poster

High-fidelity text-to-image and text-to-video generation typically relies on Classifier-Free Guidance (CFG), but achieving optimal results often demands computationally expensive sampling schedules. In this work, we propose MAMBO-G, a training-free acceleration framework that significantly reduces c…

Accelerating Diffusion Sampling via Exploiting Local Transition Coherence

ICCV 2025poster

Text-based diffusion models have made significant breakthroughs in generating high-quality images and videos from textual descriptions. However, the lengthy sampling time of the denoising process remains a significant bottleneck in practical applications. Previous methods either ignore the statistic…

BACON: Improving Clarity of Image Captions via Bag-of-Concept Graphs

CVPR 2025poster

Advancements in large Vision-Language Models have brought precise, accurate image captioning, vital for advancing multi-modal image understanding and processing. Yet these captions often carry lengthy, intertwined contexts that are difficult to parse and frequently overlook essential cues, posing a…
