Book ChapterDOI

Supervising random forest using attribute interaction networks

TL;DR: A hybrid algorithm, MIN-guided RF (MINGRF), which overlays the neighborhood structure of MIN onto the growth of trees and concludes that MINGRF produces trees with a better accuracy at a smaller computational cost.
Journal ArticleDOI

High-resolution elemental mapping of human placental chorionic villi using synchrotron X-ray fluorescence spectroscopy

TL;DR: The aims were to pilot placental biopsy specimen preparation techniques that could be integrated into an ongoing epidemiology birth cohort study without harming rates of sample acquisition and investigate a thaw-fixation protocol for archived specimens stored at −80 °C.
Proceedings ArticleDOI

A screening-testing approach for detecting gene-environment interactions using sequential penalized and unpenalized multiple logistic regression.

TL;DR: A novel approach that combines elements of screening-testing and hierarchical penalized regression is proposed that addresses the challenges of both poor power and omitted variable bias encountered with traditional G × E interaction detection methods.
