Synthetic data generation shows limitations in specialized computer vision tasks

A new research paper published on arXiv explores the limitations of using synthetic data generated by diffusion models for specialized, data-scarce domains in computer vision. While synthetic data has shown success with large datasets like ImageNet, this study found it did not consistently outperform traditional data augmentation methods on five specific trauma classification tasks. The research identified several failure modes, including model memorization, distributional drift, and the generation of overly simplified canonical images that are easier to classify than real-world data.
