T2V-Turbo: Breaking the Quality Bottleneck of Video Consistency Model with Mixed Reward Feedback

Jiachen Li, Weixi Feng, Tsu-Jui Fu +4

Diffusion-based text-to-video (T2V) models have achieved significant success but continue to be hampered by the slow sampling speed of their iterative sampling processes. To addres…

Reward Guided Latent Consistency Distillation

Jiachen Li, Weixi Feng, Wenhu Chen +1

Latent Consistency Distillation (LCD) has emerged as a promising paradigm for efficient text-to-image synthesis. By distilling a latent consistency model (LCM) from a pre-trained t…

Discffusion: Discriminative Diffusion Models as Few-shot Vision and Language Learners

Xuehai He, Weixi Feng, Tsu-Jui Fu +6

Diffusion models, such as Stable Diffusion, have shown incredible performance on text-to-image generation. Since text-to-image generation often requires models to generate visual c…
