Statistical Concepts and Metrics of Algorithm Bias and Fairness

In the first entry of this series, we examined how algorithms can be biased on a variety of factors, including their underlying data, biased individuals creating models, or from statistical mischaracterizations from models themselves.  In this entry, Caleb Hearn et al. explore how bias in algorithms is identified and quantified according to a few different statistical concepts and metrics.

Introduction to Algorithmic Bias

Algorithms leverage existing data to predict an outcome, using inputs that are associated with the outcome.  One problem with the forthcoming tide of machine learning algorithms is that such algorithms can be biased.  In this blog, we start exploring the concept of "Algorithmic Bias"

Introduction to Performance Drift

Algorithms are routinely used in the clinic to make decisions on patient care. Over time these algorithms may deteriorate in performance. Here, we start the explore the concept of “performance drift”.

How do we regulate AI in healthcare?

AI's role in our daily lives continues to become more omnipresent and healthcare is no exception.  As AI becomes more routinely incorporated in healthcare, a central question becomes – how do we regulate it?

Welcome to the Human-Algorithm Collaboration Lab (HACLab)!

Founded at the Perelman School of Medicine and the Abramson Cancer Center at the University of Pennsylvania, we are a laboratory focusing on the development, validation, implementation, and scaling of advanced algorithms in clinical care and health policy.

Patient Generated Health Data?

A branch of AI and computer science which focuses on the use of data and algorithms to imitate the way that humans learn, gradually improving its accuracy (source:IBM)

The health and well-being of a person with cancer from the time of diagnosis until the end of life. This includes issues related to follow-up care, late effects of treatment, cancer recurrence, second cancers, and quality of life (source:cancer.gov)

Systematic and repeatable errors in a computer system that create unfair outcomes, such as privileging one arbitrary group of users over others. It also, occurs when an algorithm produces results that are systemically prejudiced due to erroneous assumptions in the machine learning process (source:FSU)

The data relating to patient health status and/or the delivery of health care routinely collected from a variety of sources- electronic health records (EHRs), claims and billing activities, pghd, product and disease registries (source:FDA)

 Health-related data created, recorded, or gathered by or from patients (or family members or other caregivers) to help address a health concern (source:healthit)
