Google Research has developed a new method for generating differentially private synthetic photo albums. This approach uses an intermediate text representation and a hierarchical generation process to ensure thematic coherence and character consistency across multiple images. By first creating text summaries of albums and then detailed captions for individual photos, the system can generate synthetic albums that are representative of real data while protecting individual privacy. This method addresses the need for structured, multi-modal synthetic data beyond simple text or individual images. AI
