Diffusion models have achieved remarkable performance on a wide range of generative tasks, yet training them from scratch is notoriously resource-intensive, typically requiring millions of training images and many GPU days. Motivated by a data-centric view of this bottleneck, we adopt a condensation
The unification of generative details and discriminative semantics presents a structural paradox in \textit{diffusion-based representation learning}. Early approaches decouple semantics from generation, inevitably compromising representational completeness (i.e., \textit{information split}). While r…
