WIDER-FAIR: An Annotated Version of the WIDER-FACE Dataset for Fairness Evaluation

arXiv:2606.31704v1 Announce Type: cross Abstract: The deployment of face detection models in real-world applications raises important fairness concerns, as these systems may showcase performance disparities across demographic groups. A key obstacle to studying and mitigating such biases is the lack of face detection datasets with sensitive feature annotations. To address this gap, we introduce WIDER-FAIR, a new dataset built on the widely used WIDER-FACE benchmark, manually annotated with the perceived ethnicity and sex of each face. The dataset contains 16,256 images annotated across four eth

Why this matters
Why now

The increasing deployment of face detection models highlights critical fairness concerns, making the lack of robust datasets for bias evaluation a pressing issue.

Why it’s important

This dataset provides a crucial tool for developers and researchers to identify and mitigate biases in AI systems, improving the ethical deployment of artificial intelligence.

What changes

The availability of WIDER-FAIR enables more rigorous fairness evaluations of face detection models, potentially leading to more equitable and less discriminatory AI applications.

Winners
  • · AI ethicists
