- BiasPainter: Fairness Analysis of AI Image Generators
-
Proposed BiasPainter, a metamorphic testing framework that can accurately, automatically and comprehensively trigger social bias in image generation models.
-
Built an image dataset and a prompt dataset based on publicly accessible data sources, and designed a set of metamorphic relations to evaluate the bias of image generation models.
-
Evaluated the bias of mainstream image generation models, including commercial models like Stable Diffusion XL and MidJourney.
- Research Assistant, CUHK CSE Dept., Sep 2022 – Feb 2022
- Bias Evaluation on Open-domain Question Answering Systems
-
Conducted experiments on triggering bias in question answering (QA) systems.
Designed a standardized algorithm to evaluate the bias of different QA models.
