De-black-boxing health AI: demonstrating reproducible machine learning computable phenotypes using the N3C-RECOVER Long COVID model in the All of Us data repository

As part of the NIH Researching COVID to Enhance Recovery (RECOVER) Initiative, researchers, including University of Colorado Department of Biomedical Informatics professor Melissa Haendel, with the National COVID Cohort Collaborative (N3C) devised and trained a machine learning-based phenotype to identify patients highly probable to have Long COVID.
