DiffusionOPD enhances multi-task learning in diffusion models via Online Policy Distillation

Researchers have introduced DiffusionOPD, a novel training paradigm for diffusion models that leverages Online Policy Distillation (OPD) to enhance multi-task learning. This method trains task-specific teacher models independently and then distills their capabilities into a single student model. DiffusionOPD extends OPD to continuous-state Markov processes, offering a closed-form KL objective that unifies stochastic and deterministic refinement. Experiments demonstrate that DiffusionOPD outperforms existing multi-reward and cascade RL baselines in training efficiency and final performance across various benchmarks. AI

IMPACT This research could lead to more efficient and effective multi-task learning for generative AI models.

    DiffusionOPD: A Unified Perspective of On-Policy Distillation in Diffusion Models

    arXiv:2605.15055v2 Announce Type: replace Abstract: Reinforcement learning has emerged as a powerful tool for improving diffusion-based text-to-image models, but existing methods are largely limited to single-task optimization. Extending RL to multiple tasks is challenging: joint…
