  In this paper, we propose ProCreate, a simple and easy-to-implement method to
improve sample diversity and creativity of diffusion-based image generative
models and to prevent training data reproduction. ProCreate operates on a set
of reference images and actively propels the generated image embedding away
from the reference embeddings during the generation process. We propose FSCG-8
(Few-Shot Creative Generation 8), a few-shot creative generation dataset on
eight different categories -- encompassing different concepts, styles, and
settings -- in which ProCreate achieves the highest sample diversity and
fidelity. Furthermore, we show that ProCreate is effective at preventing
replicating training data in a large-scale evaluation using training text
prompts. Code and FSCG-8 are available at
https://github.com/Agentic-Learning-AI-Lab/procreate-diffusion-public. The
