Fair models in machine learning
Description
Fair machine learning models: estimation, tuning and prediction.
Details
fairml implements key algorithms for learning machine learning models while enforcing fairness with respect to a set of observed sensitive (or protected) attributes.
Currently fairml implements the following algorithms (references below):
-
nclm(): the non-convex formulation of fair linear regression model from Komiyama et al. (2018). -
frrm(): the fair (linear) ridge regression model from Scutari, Panero and Proissl (2022). -
fgrrm(): thefair generalized (linear) ridge regression model from Scutari, Panero and Proissl (2022), supporting the Gaussian, binomial, Poisson, multinomial and Cox (proportional hazards) families. -
zlrm(): the fair logistic regression with covariance constraints from Zafar et al. (2019). -
zlrm(): a fair linear regression with covariance constraints following Zafar et al. (2019).
Furthermore, different fairness definitions can be used in frrm()
and fgrrm():
-
"sp-komiyama": the statistical parity fairness constraint from Komiyama et al. (2018); -
"eo-komiyama": the analogous equality of opportunity constraint built on the proportion of variance (or deviance) explained by sensitive attributes; -
"if-berk": the individual fairness constraint from Berk et al. (2017) adapted in Scutari, Panero and Proissl (2022); user-provided functions for custom definitions.
In addition, fairml implements diagnostic plots, cross-validation,
prediction and methods for most of the generics made available for linear
models from lm() and glm(). Profile plots to trace key model
and goodness-of-fit indicators at varying levels of fairness are available
from
fairness.profile.plot().
