TL;DR: This work shows the need to explicitly account for underspecification in modeling pipelines that are intended for real-world deployment in any domain, and shows that this problem appears in a wide variety of practical ML pipelines.

Maintaining fairness across distribution shift: do we have viable solutions for real-world applications?
Jessica Schrouff,Natalie Harris,Oluwasanmi Koyejo,Ibrahim M. Alabdulmohsin,Eva Schnider,Krista Opsahl-Ong,Alex Brown,Subhrajit Roy,Diana Mincu,Christina Chen,Awa Dieng,Yuan Liu,Vivek T. Natarajan,Alan Karthikesalingam,Katherine C. Heller,Silvia Chiappa,Alexander D'Amour +16 more
TL;DR: In this paper , the authors explore the settings in which recently proposed mitigation strategies are applicable by referring to a causal framing, and show that real-world applications are complex and often invalidate the assumptions of such methods.

Diagnosing failures of fairness transfer across distribution shift in real-world medical settings
Jessica Schrouff,Natalie Harris,Oluwasanmi Koyejo,Ibrahim M. Alabdulmohsin,Eva Schnider,Krista Opsahl-Ong,Alex Brown,Subhrajit Roy,Diana Mincu,Christina Chen,Awa Dieng,Yuan Liu,Vivek T. Natarajan,Alan Karthikesalingam,Katherine Heller,Silvia Chiappa,Alexander D'Amour +16 more
TL;DR: In this article , the authors adopt a causal framing to motivate conditional independence tests as a key tool for characterizing distribution shifts, which can help diagnose failures of fairness transfer, including cases where real-world shifts are more complex than is often assumed in the literature.

Disability prediction in multiple sclerosis using performance outcome measures and demographic data
Subhrajit Roy,Diana Mincu,Lev Proleev,Negar Rostamzadeh,Chintan Ghate,Natalie Harris,Christina Chen,Jessica Schrouff,Nenad Tomasev,F. Lee Hartsell,Katherine Heller +10 more
TL;DR: This work used multi-dimensional, affordable, physical and smartphone-based performance outcome measures (POM) in conjunction with demographic data to predict multiple sclerosis disease progression, and results are the first to show that it is possible to predict disease progression.
Journal ArticleDOI
Boosting the interpretability of clinical risk scores with intervention predictions
Eric Loreaux,Ke Yu,Jonas Kemp,Martin G. Seneviratne,Christina Chen,Subhrajit Roy,Ivan Protsyuk,Natalie Harris,Alexander D'Amour,Steve Yadlowsky,Ming-Jun Chen +10 more
TL;DR: It is shown how combining typical risk scores, such as the likelihood of mortality, with future intervention probability scores leads to more interpretable clinical predictions, and a joint model of intervention policy and adverse event risk is proposed.
