The Fairness Trade-Off: Can AI Be Unbiased Without Losing Its Edge?

December 28, 2025 by BBG News

Ablation studies reveal a complex interplay between biases affecting perceptions of education and demographic groups, demonstrating that interventions minimizing both [latex] KL [/latex] divergences-representing ideal outcomes-are possible, though frequently traded off against scenarios where one bias diminishes while the other intensifies, and occasionally resulting in the amplification of both.

New research reveals that removing demographic information from large language models to address bias isn’t a simple fix, and can actually reduce performance.

Keeping Robots on Their Feet: A Wireless Balance System

December 27, 2025 by BBG News

During walking in place, the center of pressure dynamically shifts between the robot’s feet - remaining centered when both feet are grounded, and moving to the single supporting foot upon lifting the other - demonstrating a stable gait achieved through continuous balance adjustment.

Researchers have developed a cost-effective wireless system that allows a 29-DoF humanoid robot to dynamically maintain balance during complex movements.
