Sequential Computer Experimental Design for Estimating an Extreme Probability or Quantile
Hao Chen, William J. Welch
A computer code can simulate a system's propagation of variation from random inputs to output measures of quality. Our aim here is to estimate a critical output tail probability or…
Regression Phalanxes
Hongyang Zhang, William J. Welch, Ruben H. Zamar
Tomal et al. (2015) introduced the notion of "phalanxes" in the context of rare-class detection in two-class classification problems. A phalanx is a subset of features that work we…
Ensembles of phalanxes across assessment metrics for robust ranking of homologous proteins
Jabed H Tomal, William J Welch, Ruben H Zamar
Two proteins are homologous if they have a common evolutionary origin, and the binary classification problem is to identify proteins in a candidate set that are homologous to a par…
Ensembling classification models based on phalanxes of variables with applications in drug discovery
Jabed H. Tomal, William J. Welch, Ruben H. Zamar
Statistical detection of a rare class of objects in a two-class classification problem can pose several challenges. Because the class of interest is rare in the training data, ther…
