Post-Generation Curation of Synthetic Images via Homogeneous-Heterogeneous Splitting

arXiv:2607.02637v1 Announce Type: cross Abstract: Recent generative models can produce high-quality synthetic images, offering scalable training training data for data-hungry models. Existing approaches to exploiting this potential typically involve 1) training or fine-tuning generators, or 2) using lightweight post-hoc adaptation like prompt engineering or inference-time guidance, making them generator-specific and expertise-intensive. We study a complementary question: given a fixed pool of generated images, can downstream utility be improved purely by selecting an informative subset? The an

Why this matters
Why now

The proliferation of generative AI models necessitates efficient methods for leveraging synthetic data, and this research addresses a critical bottleneck in post-generation utility.

Why it’s important

Improving the utility of synthetic images through selection rather than complex modifications can significantly boost training data scalability for AI models, impacting numerous data-hungry applications.

What changes

The focus shifts from solely optimizing generative models or prompt engineering to effectively curating existing pools of synthetic data, potentially democratizing access to high-quality training assets.
