Researchers have introduced SwiftExplorer, a novel plugin designed to enhance the alignment of diffusion models without requiring extensive training. This method addresses issues of reduced generation diversity and computational inefficiency often seen in existing training-free alignment techniques. SwiftExplorer employs an Inheritance-Restart mechanism to maintain diversity and an Inheritance-Restart exploration mechanism to prevent early convergence, thereby increasing the likelihood of finding high-reward generation trajectories. Additionally, its Quality-Efficiency arbitration mechanism prunes redundant signals and dynamically stops generation to optimize compute usage while ensuring completeness and marginal reward gain. Experiments demonstrate SwiftExplorer's superior performance across various metrics, including preference, fidelity, diversity, and richness. AI
