FGM-HD: Boosting Generation Diversity of Fractal Generative Models through Hausdorff Dimension Induction

AAAI 2026technical

Improving the diversity of generated results while maintaining high visual quality remains a significant challenge in image generation tasks. Fractal Generative Models (FGMs) are efficient in generating high-quality images, but their inherent self-similarity limits the diversity of output images. To
