Exquisite demand exists for customizing the pretrained large text-to-image
model, $\textit{e.g.}$, Stable Diffusion, to generate innovative concepts, such
as the users themselves. However, the newly-added concept from previous
customization methods often shows weaker combination abilities than the
original ones even given several images during training. We thus propose a new
personalization method that allows for the seamless integration of a unique
individual into the pre-trained diffusion model using just $\textbf{one facial
photograph}$ and only $\textbf{1024 learnable parameters}$ under $\textbf{3
minutes}$. So as we can effortlessly generate stunning images of this person in
any pose or position, interacting with anyone and doing anything imaginable
from text prompts. To achieve this, we first analyze and build a well-defined
celeb basis from the embedding space of the pre-trained large text encoder.
Then, given one facial photo as the target identity, we generate its own
embedding by optimizing the weight of this basis and locking all other
parameters. Empowered by the proposed celeb basis, the new identity in our
customized model showcases a better concept combination ability than previous
personalization methods. Besides, our model can also learn several new
identities at once and interact with each other where the previous
customization model fails to. The code will be released.

研究提出了一种新的个性化方法，通过向先前训练好的扩散模型中添加唯一人物的面部照片和仅有 1024 个可学习参数，能够轻松地生成与任何文本提示想象的任何姿势或位置互动的惊人图像，其中使用了明星精神基础，并可以同时学习多个新身份并相互交互。
