摘要:
扩散模型已成为高质量图像生成和编辑的强大工具,但引导这些模型产生特定输出仍然是一个挑战。传统方法依赖于条件机制,如文本提示或语义图,这些需要大量标注的数据集。在这项初步工作中,我们探索了以预训练自监督模型的表示为条件的扩散模型。自条件机制不仅提高了无条件图像生成的质量,还提供了一个可用于控制生成的表示空间。我们通过识别变化方向来探索这个条件空间,并展示了在平滑性和分离性方面的有前景的特性。
英文摘要:
Diffusion models have emerged as powerful tools for high-quality image generation and editing, but guiding these models to produce specific outputs remains a challenge. Conventional approaches rely on conditioning mechanisms, such as text prompts or semantic maps, which require extensively annotated datasets. In this preliminary work, we explore diffusion models conditioned on representations from a pre-trained self-supervised model. The self-conditioning mechanism not only improves the quality of unconditional image generation, but also provides a representation space that can be used to control the generation. We explore this conditioning space by identifying directions of variations, and demonstrate promising properties in terms of smoothness and disentanglement.
