A new arXiv paper (2610.12102) by Shanchuan Lin, Fu-Yun Wang, Haoqi Fan et al. proposes data-space iteration, a new paradigm for few-step generation.
- Existing few-step methods iterate along the probability flow and require a manually chosen timestep discretization that is costly to tune and inflexible across samples
- The new framework drops flow discretization entirely: a shared generator refines predictions directly in data space, each iteration trained to produce the best sample within its capacity
- Integrates with distribution matching distillation (DMD) with minimal changes, enabling controlled comparisons
- On class-conditional ImageNet 256x256, it beats standard discretization baselines and matches or improves schedule-search variants without schedule-specific training
