Tiny Synthetic Datasets, Big Results for Vision Models
Tiny synthetic images, big model results
Training today’s vision systems usually starts from large, self-supervised backbones. This work shows you can replace huge real datasets with a handful of smartly crafted, synthetic images—without losing performance.
The trick, called Linear Gradient Matching, distills a small set of images so that, after a frozen feature extractor, they push a linear classifier’s gradients to mimic those from the real data.
- Optimized for linear probes on top of pre-trained models (no training from scratch).
- Beats real-image baselines with far fewer samples.
- Generalizes across backbones: e.g., a CLIP probe trained on a dataset distilled using a DINO model performs competitively.
- Shines on fine-grained classification.
- Doubles as a lens into model behavior—revealing embedding-space similarity and sensitivity to spurious correlations.
Why it matters: faster experiments, lower compute and memory, and potential privacy benefits when sharing distilled datasets instead of raw data.
