CoDMD: Copula-aware Distribution Matching Distillation for Fast Video Generation
Wenhu Zhang, Kun Cheng, Changyuan Wang +7
Few-step distillation for video diffusion models has attracted significant attention, driven by the urgent demand for efficient deployment in real-world scenarios. However, Distrib…
Teacher-Feature Drifting: One-Step Diffusion Distillation with Pretrained Diffusion Representations
Yuan Zhang, Chenyi Li, Haodong Yu +8
Sampling from pretrained diffusion and flow-matching models typically requires many forward passes to generate diverse and high-fidelity images. Existing distillation methods often…
Continuous Semi-Implicit Models
Longlin Yu, Jiajun Zha, Tong Yang +4
Semi-implicit distributions have shown great promise in variational inference and generative modeling. Hierarchical semi-implicit models, which stack multiple semi-implicit layers,…
Invertible Attention
Jiajun Zha, Yiran Zhong, Jing Zhang +2
Attention has been proved to be an efficient mechanism to capture long-range dependencies. However, so far it has not been deployed in invertible networks. This is due to the fact…
