Do unbalanced data have a negative effect on LDA? [PDF]

open access: yes, 2008
For two-class discrimination, Xie and Qiu [The effect of imbalanced data sets on LDA: a theoretical and empirical analysis, Pattern Recognition 40 (2) (2007) 557–562] claimed that, when covariance matrices of the two classes were unequal, a (class ...

Assessment of Sonoelastography as Diagnosis Tool of Inflammatory Myopathies [PDF]

open access: yesApplied Medical Informatics, 2010
Background: Inflammatory myopathies represent a special group of pathology. Establishing the correct diagnosis in the early phase and a better follow-up are the main objective for improving the life quality of these patients.

Receiver operating characteristic (ROC) curve analyses.

open access: yes, 2016
The ROC plots for CEA (A), CA153 (B), CA125 (C) and the combination of CEA and CA153 (D) were used to differentiate breast cancer from benign disease. AUC, area under the receiver operating characteristic curve; CI, confidence interval.

Image saliency detection based on geodesic‐like and boundary contrast maps

open access: yesETRI Journal, 2019
Image saliency detection is the basis of perceptual image processing, which is significant to subsequent image processing methods. Most saliency detection methods can detect only a single object with a high‐contrast background, but they have no effect on

On Boundary Correction in Kernel Estimation of ROC Curves

open access: yesAustrian Journal of Statistics, 2016
The Receiver Operating Characteristic (ROC) curve is a statistical tool for evaluating the accuracy of diagnostics tests. The empirical ROC curve (which is a step function) is the most commonly used non-parametric estimator for the ROC curve.

Non Parametric Confidence Intervals for Receiver Operating Characteristic Curves [PDF]

open access: yes
We study methods for constructing confidence intervals, and confidence bands, for estimators of receiver operating characteristics. Particular emphasis is placed on the way in which smoothing should be implemented, when estimating either the ...

Nonparametric Predictive Inference for Ordinal Data and Accuracy of Diagnostic Tests [PDF]

open access: yes, 2012
This thesis considers Nonparametric Predictive Inference (NPI) for ordinal data and accuracy of diagnostic tests. We introduce NPI for ordinal data, which are categor- ical data with an ordering of the categories.
