Fairness, Explainability & Robustness in Machine Learning

Celia Cintas

Abstract

Recent years have seen an overwhelming body of work on fairness and bias in Machine Learning (ML) models. This is not unexpected, as fairness is a complex and multi-faceted concept that depends on context and culture. Particularly in machine learning, fairness is an increasingly important concern as models are used to support decision-making in high-stakes applications such as mortgage lending, hiring, and diagnosis in healthcare. ML models depend heavily on data to learn discriminatory patterns. The discrimination becomes objectionable when unprivileged groups are systematically penalized. As researchers, we need to proactively pursue understanding the social choices and stereotypes that have been translated to the data and ML models by working closely with stakeholders, potential users, domain experts, and social researchers. In this lecture, we will focus on the recent advancements in the field to better understand and mitigate unwanted bias in ML models with specifics examples in healthcare.
