Evolving Prompts for Synthetic Image Generation with Genetic Algorithm

Khoi Dinh Tran, Dat Viet Bui, Ngoc Hoang Luong

MAPR 2023

October 2023

This paper enhances the EvoGen framework by implementing an improved genetic algorithm with an elitism mechanism that preserves high-performing prompts during evolution. We introduce a cosine loss function as the fitness measure, resulting in faster convergence and better image guidance compared to previous approaches. Our modifications address the inconsistency issues in existing text-to-image prompt evolution methods, making the automatic generation of high-quality, preference-satisfying prompts more reliable.
