About this paper

Chong Huang, Arash Nourian, Kevin Griest

Researchers from FICO AI Research detail various "hidden technical debts" concerning fairness across the entire machine learning lifecycle in financial services. They propose a "fairness by design" paradigm to proactively integrate fairness considerations from the initial stages, addressing complexities in data handling, metric selection, production monitoring, debiasing, and CI/CD pipelines.

Key insights

  • Fairness in ML is a system-level challenge, not solely an algorithmic one, demanding holistic integration across the entire lifecycle to prevent the accumulation of hidden technical debt.
  • Specific technical debts, such as the use of proxy variables or the difficulty in selecting appropriate fairness metrics, emerge silently and become prohibitively expensive to resolve once systems are in production.
  • The highly regulated and high-stakes nature of the financial industry necessitates a proactive 'fairness by design' approach to ensure robust, auditable, and inherently fair ML systems.
