Phebe Vayanos

"Interpretability, Robustness, and Fairness in Predictive and Prescriptive Analytics for Social Impact"

Presentation by Phebe Vayanos
WiSE Gabilan Assistant Professor
University of Southern California

Wednesday, April 6
3:30pm - Graduate Seminar
4:30pm - Reception

About the seminar:

Motivated by problems in homeless services delivery, suicide prevention, and substance use prevention, we consider the problem of learning optimal interpretable, robust, and fair models in the form of decision-trees to assist with decision-making in socially sensitive, high-stakes settings. We propose new models and algorithms, showcase their flexibility, and theoretical and practical benefits, and demonstrate substantial improvements over the state of the art. This presentation is based on the following papers:

“Strong Optimal Classification Trees” (pdf)

“Learning Optimal Fair Classification Trees” (pdf)

“Learning Optimal Prescriptive Trees from Observational Data” (pdf)

“Optimal Robust Classification Trees” (pdf)
