EP-CFG: Energy-Preserving Classifier-Free Guidance

2024 · arXiv (Cornell University)

Classifier-free guidance (CFG) is widely used in diffusion models but often\nintroduces over-contrast and over-saturation artifacts at higher guidance\nstrengths. We present EP-CFG (Energy-Preserving Classifier-Free Guidance),\nwhich addresses these issues by preserving the energy distribution of the\nconditional prediction …
