NCL: Textual Backdoor Defense Using Noise-Augmented Contrastive Learning

2023

At present, backdoor attacks attract attention as they do great harm to deep learning models. By poisoning the training data, the adversary makes the model trained based on this dataset being injected with a backdoor. …

Membership Inference on Text-to-Image Diffusion Models via Conditional Likelihood Discrepancy

2024 · arXiv (Cornell University)

Text-to-image diffusion models have achieved tremendous success in the field of controllable image generation, while also coming along with issues of privacy leakage and data copyrights. Membership inference arises in these contexts as a potential …
