Developing a differentially private retrieval-augmented diffusion model (DP-RDM) for high-quality image generation with privacy guarantees.
摘要
The content introduces DP-RDM, a novel approach for adapting diffusion models to private domains without fine-tuning. It addresses the issue of sample memorization in text-to-image diffusion models and proposes a solution using differential privacy. The method utilizes retrieval augmentation to generate images based on text prompts while ensuring rigorous DP guarantees. The paper outlines the architecture, training process, and privacy guarantees of DP-RDM. Experimental results demonstrate the effectiveness of DP-RDM in generating high-quality images under a fixed privacy budget.
