ImbTreeAUC: An R package for building classification trees using the area under the ROC curve (AUC) on imbalanced datasets

SoftwareX, 2021
In this paper, we propose a novel R package, named ImbTreeAUC, for building binary and multiclass decision tree using the area under the receiver operating characteristic (ROC) curve.

Evaluating the Effectiveness of Early Warning Indicators: An Application of Receiver Operating Characteristic Curve Approach to Panel Data

Scientific Annals of Economics and Business, 2022
Early warning indicators (EWIs) of banking crises should ideally be judged on how well they function in relation to the choice issue faced by macroprudential policymakers.

Estimating the optimal linear combination of predictors using spherically constrained optimization

BMC Bioinformatics, 2022
Background In the context of a binary classification problem, the optimal linear combination of continuous predictors can be estimated by maximizing the area under the receiver operating characteristic curve.

Exact Probability Distribution for the ROC Area Under Curve

Cancers, 2022
Summary The Receiver Operating Characteristic (ROC) is a de facto standard for determining the accuracy of in vitro diagnostic (IVD) medical devices, and thus exactness in its probability distribution is crucial toward accurate statistical ...

Reliability of Systematic and Targeted Biopsies versus Prostatectomy

Bioengineering, 2023
Systematic Biopsy (SBx) has been and continues to be the standard staple for detecting prostate cancer. The more expensive MRI guided biopsy (MRITBx) is a better way of detecting cancer. The prostatectomy can provide an accurate condition of the prostate.

The Matthews correlation coefficient (MCC) should replace the ROC AUC as the standard metric for assessing binary classification

BioData Mining, 2023
Binary classification is a common task for which machine learning and computational statistics are used, and the area under the receiver operating characteristic curve (ROC AUC) has become the common standard metric to evaluate binary classifications in ...

Simple tuberculosis screening tool using signs, symptoms, and risk factors to reduce the missed opportunity in the older population

BMC Pulmonary Medicine, 2022
Background There is a growing concern on how to increase tuberculosis (TB) case detection in resource-poor settings. The healthcare facilities routinely providing services to the elderly for chronic diseases often failed to detect TB cases, causing a ...

A Model-Agnostic Algorithm for Bayes Error Determination in Binary Classification

Algorithms, 2021
This paper presents the intrinsic limit determination algorithm (ILD Algorithm), a novel technique to determine the best possible performance, measured in terms of the AUC (area under the ROC curve) and accuracy, that can be obtained from a specific ...

AUC optimization for deep learning-based voice activity detection

EURASIP Journal on Audio, Speech, and Music Processing, 2022
Voice activity detection (VAD) based on deep neural networks (DNN) have demonstrated good performance in adverse acoustic environments. Current DNN-based VAD optimizes a surrogate function, e.g., minimum cross-entropy or minimum squared error, at a given

Nonparametric confidence intervals for the area under the ROC curve

Statistica, 2013
Following an idea by Jing et al. (2005), this paper combines the empirical likelihood for the mean functional with jackknife pseudo-values obtained from the Mann-Witney two-sample statistic.
