Using Stable Diffusion with Python

Using Textual Inversion

Textual inversion (TI) is another way to provide additional capabilities to a pretrained model. Unlike Low-Rank Adaptation (LoRA), discussed in Chapter 8, which is a fine-tuning technique applied to the text encoder and the UNet attention weights, TI is a technique to add new embedding space based on the trained data.

In the context of Stable Diffusion, text embedding refers to the representation of text data as numerical vectors in a high dimensional space, allowing for manipulation and processing by machine learning algorithms. Specifically, in the case of Stable Diffusion, text embeddings are typically created using the Contrastive Language-Image Pretraining (CLIP) [6] model.

To train a TI model, you only need a ...
