Diffusion models have been successful in high-fidelity image synthesis and prompt-guided generative modeling.
Ensuring diversity in generated samples of prompt-guided diffusion models is a challenge, especially with broad semantic prompts.
Recent methods introduced diversity measures for varied generations.
The SPARKE method is proposed for prompt-aware diversity guidance, using conditional entropy.
SPARKE enables prompt-aware diversity control by dynamically conditioning diversity measurement on similar prompts.
Entropy computation in SPARKE poses challenges in large-scale generation, but the method focuses on Conditional latent RKE Score Guidance to address this.
The reduced computation complexity in SPARKE allows for diversity-guided sampling over many generation rounds on different prompts.
Numerical testing on text-to-image diffusion models shows that SPARKE improves prompt-aware diversity without significant computational costs.
