Balancing Biases and Preserving Privacy on Balanced Faces in the Wild
Demographic biases exist in current models used for facial recognition (FR).
Our Balanced Faces in the Wild (BFW) dataset is a proxy to measure bias across
ethnicity and gender subgroups, allowing one to characterize FR performances
per subgroup. We show that results are non-optimal when a single score
threshold determines whether sample pairs are genuine or imposters.
Furthermore, within subgroups, performance often varies significantly from the
global average. Thus, specific error rates only hold for populations matching
the validation data. We mitigate the imbalanced performances using a novel
domain adaptation learning scheme on the facial features extracted from
state-of-the-art neural networks, boosting the average performance. The
proposed method also preserves identity information while removing demographic
knowledge. The removal of demographic knowledge prevents potential biases from
being injected into decision-making and protects privacy since demographic
information is no longer available. We explore the proposed method and show
that subgroup classifiers can no longer learn from the features projected using
our domain adaptation scheme. For source code and data, see
