Synthetic Data Enables Any Differentiable Target

**arXiv `2604.08423`** presents a method to generate **synthetic data** that directly optimizes arbitrary `differentiable target` functions. The paper frames dataset synthesis as a differentiable objective, enabling creation of datasets tailored to any differentiable loss or performance metric and positioning synthetic-data generation as a general-purpose tool for aligning data with specific model objectives.
