SFDDM: Single-fold Distillation for Diffusion models

no code implementations23 May 2024 Chi Hong, Jiyue Huang, Robert Birke, Dick Epema, Stefanie Roos, Lydia Y. Chen

While diffusion models effectively generate remarkable synthetic images, a key limitation is the inference inefficiency, requiring numerous sampling steps.

Fabricated Flips: Poisoning Federated Learning without Data

Attacks and Defenses for Free-Riders in Multi-Discriminator GAN

no code implementations24 Jan 2022 Zilong Zhao, Jiyue Huang, Stefanie Roos, Lydia Y. Chen

To mitigate the model degradation, we propose a defense strategy against free-riders in MD-GAN, termed DFG.
