The Explainable AI Special Interest Group at the GWU Biomedical Informatics Center
"Variable Importance Scores" with Eduardo A. Trujillo Rivera, PhD
In this meeting of the Explainable Artificial Intelligence Special Interest Group Dr. Trujillo Rivera will discuss a paper by Wei-Yin Loh and Peigen Zhou (accessible through https://jds-online.org/journal/JDS/article/1250/info). In this paper, Loh and Zhou compare the performance of several variable importance scores used in predictive modeling. They observe deficiencies in some of the scoring methods, and propose a modification of the GUIDE algorithm to ensure an unbiasedness score.
