Dreambooth Stable Diffusion
This project is a Dreambooth implementation designed to personalize Stable Diffusion models. It serves as an AI image personalization tool and model tuner that enables the creation of unique subject identifiers to generate consistent, personalized images.
The system focuses on subject-driven image synthesis by fine-tuning pre-trained diffusion models on small, custom datasets. This allows the model to recognize specific people, objects, or artistic styles and place those learned subjects into diverse contexts via text-to-image conditioning.
The implementation includes a diffusion model optimizer that utilizes prior preservation regularization to prevent overfitting. It employs latent space diffusion and gradient-based weight optimization to balance identity retention with overall image quality.
