Method & Evidence

AimHow can diffusion models be fine-tuned for new concepts and styles while retaining their inherent few-step inference efficiency?
MethodOn-policy self-distillation
ProcedureThe D-OPSD paradigm trains a diffusion model to act as both teacher and student. The student model is conditioned solely on text features, while the teacher model uses both text and image multimodal features. Training minimizes the divergence between the distributions predicted by the student on its own generated outputs, effectively allowing the model to learn from its own generated trajectories under its own supervision.
