Query: Measuring Model Fairness under Noisy Covariates: A Theoretical
  Perspective   In this work we study the problem of measuring the fairness of a machine
learning model under noisy information. Focusing on group fairness metrics, we
investigate the particular but common situation when the evaluation requires
controlling for the confounding effect of covariate variables. In a practical
setting, we might not be able to jointly observe the covariate and group
information, and a standard workaround is to then use proxies for one or more
of these variables. Prior works have demonstrated the challenges with using a
proxy for sensitive attributes, and strong independence assumptions are needed
to provide guarantees on the accuracy of the noisy estimates. In contrast, in
this work we study using a proxy for the covariate variable and present a
theoretical analysis that aims to characterize weaker conditions under which
accurate fairness evaluation is possible.
  Furthermore, our theory identifies potential sources of errors and decouples
them into two interpretable parts $\gamma$ and $\epsilon$. The first part
$\gamma$ depends solely on the performance of the proxy such as precision and
recall, whereas the second part $\epsilon$ captures correlations between all
the variables of interest. We show that in many scenarios the error in the
estimates is dominated by $\gamma$ via a linear dependence, whereas the
dependence on the correlations $\epsilon$ only constitutes a lower order term.
As a result we expand the understanding of scenarios where measuring model
fairness via proxies can be an effective approach. Finally, we compare, via
simulations, the theoretical upper-bounds to the distribution of simulated
estimation errors and show that assuming some structure on the data, even weak,
is key to significantly improve both theoretical guarantees and empirical
results.
