Let words modulate diffusion – Conditional Diffusion, Cross Attention. Conceptually, textual inversion works by learning a token embedding for a new text token The normal process is: text -> embedding -> UNet denoiser. the diffusion process takes place in image-space, leading to a large inference cost due to high image dimensionalty. There are multiple ways to fine-tune Stable Diffusion, such as: Dreambooth. Seems like if you select a model that is based on SD 2. You will also learn about the theory and implementation details of LoRA and how it can improve your model performance and efficiency. Diffusion Models offer advantages in terms of training stability, efficiency, scalability, and parallelization. t = t. Diffusion adds noise gradually to the image until its unrecognizable, and a reversion diffusion process removes the noise. That's all you have to do! (Write the embedding name in the negative prompt if you are using a negative embedding). It should of course match the subject photo / concept you are trying to train. Create the embedding, now the number of vectors has become a important variable. Introduction .
