Auditing Demographic Bias in Facial Landmark Detection for Fair Human-Robot Interaction

Jos\'e M. Buenaposada, Luis Baumela, Pablo Parte, Roberto Valle

After controlling for head pose and image resolution, facial landmark detectors show no bias by gender or race but retain an age-related bias.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Notably, after accounting for these confounders, we show that performance disparities across gender and race vanish. However, we identify a statistically significant age-related effect, with higher biases observed for older individuals.

C2weakest assumption

The controlled statistical methodology successfully disentangles demographic effects from confounding visual factors such as head pose and image resolution without residual interactions or dataset-specific artifacts that could mask or create apparent biases.

C3one line summary

After accounting for confounding factors like head pose and resolution, demographic biases in facial landmark detection largely vanish except for a statistically significant age effect disadvantaging older people.
