Courses: How to Increase Lending to Women Using Machine Learning and Reject Inference

Course Description

This open-source 6-hour video course equips both product owners and data scientists with the tools they need to address bias within credit evaluation processes at financial service providers. Within the course, participants learn to deploy algorithmic solutions to rectify biases in credit evaluations, specifically focusing on the high-impact issue of mistakenly rejecting creditworthy applicants, often due to biases ingrained in evaluation models themselves. Users will walk away with:

  • Working knowledge of where gender balance vulnerabilities emerge across credit processes
  • The language needed to discuss fair lending with colleagues, in any legal or policy environment
  • Two innovative methods to directly address bias in credit evaluation processes:
    • Matching algorithms
    • Counterfactual learning
  • Working knowledge of Women’s World Banking’s tested approach to assessing bias and balance at various stages in a credit evaluation process, with a particular focus on data and decision-making engines
  • Real-world examples and insights from credit evaluation balance audits with financial institutions spanning three continents

Course Outline

The first section (Section I) of this course is designed for product owners and data scientists alike, with no prior knowledge or technical background required. This section conveys the foundational knowledge necessary to understand and address bias against rejected applicants. It covers core concepts such as credit evaluation, bias in credit evaluation, the meaning of fairness in this context, algorithmic bias, and reject inference.

The second section (Section II) requires technical expertise and is suited for those familiar with machine learning concepts. We will introduce matching algorithms, explaining how to integrate these with machine learning to identify creditworthy applicants who were erroneously rejected. Additionally, the course will cover counterfactual learning and its applications in reject inference.

By the end of this course, participants will have working knowledge of credit evaluation, bias in credit evaluation, fair lending, and the application of machine learning to foster a fair credit evaluation process.

This course would not have been possible without the efforts of many individuals who contributed to the ideas, the content, the production, and the resources necessary to ensure is success.

Course content was developed in partnership with State University of New York at Albany. Dr. Charalampos Chelmis and PhD candidates Sadia Rahman and Mahsa Azarshab contributed expertise that enhanced the rigor of the methods we jointly developed for reject inference.

Within Women’s World Banking, Dr. Megan Dwyer Baumann aided in curriculum development; Chelsea Bennington and Arianne Wunder worked on the communications aspects of the course; Molly Burns ensured the project continued to be aligned with its goals; Dr. Sonja Kelly and Pallavi Madhok provided feedback, and video producer Dakota Lupo led on production.
