Learning Warm Starts for the Simplex Method from Measured Solver Cost
Felix Parker, Danielle A. Ripsman, Emmett Springer +1
Learned warm starts for the simplex method build starting bases using predictions of which variables will be basic at optimality. Prior work has shown that starting bases predicted…
An interpretable data-driven approach to optimizing clinical fall risk assessment
Fardin Ganjkhanloo, Emmett Springer, Erik H. Hoyer +3
In this study, we aim to better align fall risk prediction from the Johns Hopkins Fall Risk Assessment Tool (JHFRAT) with additional clinically meaningful measures via a data-drive…
Joint Score-Threshold Optimization for Interpretable Risk Assessment
Fardin Ganjkhanloo, Emmett Springer, Erik H. Hoyer +2
Risk assessment tools in healthcare commonly employ point-based scoring systems that map patients to ordinal risk categories via thresholds. While electronic health record (EHR) da…
