Balancing the accuracy rates of majority and minority classes is challenging in imbalanced classification. Furthermore, data characteristics have a significant impact on performance classifiers, which are generally neglected by existing evaluation methods. The objective this study to introduce new criterion comprehensively evaluate classifiers. Specifically, we an efficiency curve that establis...

The receiver operating characteristic (ROC) has emerged as the gold standard for assessing and comparing the performance of classifiers in a wide range of disciplines including the life sciences. ROC curves are frequently summarized in a single scalar, the area under the curve (AUC). This article discusses the caveats and pitfalls of ROC analysis in clinical microarray research, particularly in...

BACKGROUND Different methods of evaluating diagnostic performance when comparing diagnostic tests may lead to different results. We compared two such approaches, sensitivity and specificity with area under the Receiver Operating Characteristic Curve (ROC AUC) for the evaluation of CT colonography for the detection of polyps, either with or without computer assisted detection. METHODS In a mul...

Detection and alarm of leakage hydrogen (H2) gas is an extremely important issue needed to be addressed. In this study, we fabricated calibation portable devices based on the H2 sensor using SnO2 thin film with Pd nanoscale catalytic as a sensing layer. For practical application sensor, designed realized PCB circuit boards, microprocessors, data processing, output signals, storage, power source...
