Cx Talk: Abhijnan Chakraborty | Fairness in Algorithmic Decision Making



Where: Bloomberg Center 201

When: 2:30pm, Monday May 20, 2019


Abstract:

Algorithmic (data-driven) decision making is increasingly being used to assist or replace human decision making in domains with high societal impact, such as banking (estimating creditworthiness), recruiting (ranking applicants), judiciary (offender profiling) and journalism (recommending news-stories). Consequently, in recent times, multiple research works have attempted to identify (measure) bias or unfairness in algorithmic decisions and proposed mechanisms to control (mitigate) such biases. However, the emphasis has been on fairness in classification or regression tasks, and fairness issues in other scenarios remain relatively unexplored. In this talk, I’ll cover our recent works on fairness in recommendation and matching systems. I’ll introduce the notions of fairness in these contexts and propose techniques to achieve them. Additionally, I’ll briefly touch upon the possibility of utilizing user interface of platforms (choice architecture) to achieve fair outcomes in certain scenarios. I will conclude the talk with a list of open questions and directions for future work.
