  Diffusion-based text-to-image models have rapidly gained popularity for their
ability to generate detailed and realistic images from textual descriptions.
However, these models often reflect the biases present in their training data,
especially impacting marginalized groups. While prior efforts to debias
language models have focused on addressing specific biases, such as racial or
gender biases, efforts to tackle intersectional bias have been limited.
Intersectional bias refers to the unique form of bias experienced by
individuals at the intersection of multiple social identities. Addressing
intersectional bias is crucial because it amplifies the negative effects of
discrimination based on race, gender, and other identities. In this paper, we
introduce a method that addresses intersectional bias in diffusion-based
text-to-image models by modifying cross-attention maps in a disentangled
manner. Our approach utilizes a pre-trained Stable Diffusion model, eliminates
the need for an additional set of reference images, and preserves the original
quality for unaltered concepts. Comprehensive experiments demonstrate that our
method surpasses existing approaches in mitigating both single and
intersectional biases across various attributes. We make our source code and
debiased models for various attributes available to encourage fairness in
generative models and to support further research.
