A Fair Classifier Using Kernel Density Estimation

As machine learning becomes prevalent in a widening array of sensitive applications such as job hiring and criminal justice, one critical aspect that machine learning classifiers should respect is to ensure fairness: guaranteeing the irrelevancy of a prediction output to sensitive attributes such as gender and race. In this work, we develop a kernel density estimation trick to quantify fairness measures that capture the degree of the irrelevancy. A key feature of our approach is that quantified fairness measures can be expressed as differentiable functions w.r.t.
