IEOR Seminar Series: Dr. Swati Gupta, Georgia Tech
October 24, 2022 @ 3:30 pm – 4:30 pm
IEOR Seminars occur on Mondays throughout the fall semester in room 3108 of Etcheverry Hall. Seminars feature leading-edge research from experts in industrial engineering and operations research who come from local, national, and international institutions. Seminars are open to students, faculty, and the public.
Title: Bridging Ethical Algorithms, Law, and Practice: Hiring and Beyond
Abstract: Optimization and statistical models based on historical and socio-economic data that do not incorporate fairness desiderata can lead to unfair, discriminatory, or biased outcomes. These are expected to be further exacerbated by the scale and adoption of cutting-edge technologies, especially in the aftermath of the current pandemic. New ideas are needed to mitigate the harm of socio-economic trends embedded in the data, ensure that the developed systems are accountable under uncertainty, and reduce a deeper propagation of biases in multi-level decisions.
In this talk, I will first discuss opportunities to develop ethical hiring pathways. Recent run-ins of Microsoft and Well Fargo with the Labor Department’s Office of Federal Contract Compliance Programs (OFCCP) highlight a paradox: failing to address workforce imbalance can result in legal sanctions and scrutiny, but proactive measures to address these issues might result in the same legal conflict. I will propose that partially-ordered sets, “posets”, can transparently account for known uncertainties and biases in evaluation data, giving rise to an interesting class of optimization problems. I will discuss incorporating posets in the online secretary framework, which has been classically used to model the online selection of k candidates from a streaming set of N. Using techniques from the matroid secretary literature and order theory, I will show near-optimal competitive ratios for maximizing the true total utility of hired candidates, even with access to only a partial order on the candidates. Keeping in mind the requirements of U.S. anti-discrimination law, however, certain interventions based on demographic data can be construed as illegal (e.g., quotas). I will discuss the tensions with the law and ways to argue the legal feasibility of our proposed approach. This is based on joint work with Deven Desai and Jad Salem. I will further discuss new challenges in optimization that can help with ethical decision-making in the context of other applications such as admissions, detection of critical diseases like sepsis, facility location, and gerrymandering.
