Maximizing the area under the receiver operating characteristic curve (AUC) is a standard approach to imbalanced classification. So far, various supervised AUC optimization methods have been developed and they are also extended to semi-supervised scenarios to cope with small sample problems. However, ...
aThe method achieved an overall accuracy of 84.5% and the area under the ROC curve (AUC) of 0.822 by Jackknife test, when a subset included 10 optimized features. Furthermore, on the same data, we compared our predictor with other existing methods, including R-score-based method and D-scor...
Simple and precise UV spectrophotometric method by area under curve [AUC] - have been developed and validated for the estimation of ofloxacin in bulk and its tablet formulation. The standard and sample solutions of ofloxacin were prepared in 0.1 N hydrochloric ...
curve, which is not of the binormal form. They parameterize the ROC curve incorrectly, and hence produce biased partial AUC estimates (Table 2). The largest bias was observed with the normal-distributions estimator. In contrast to this estimator and those of Pepe and Metz, the nonparametric ...
Moreover, empirical XANES data gave the chance to register the kinetic curve and to determine the rate constant of the studied reaction. It was found that reaction is relatively slow (second-order rate constant k = 3.66 · 10-5 M-1s) and lead to the gold metallic phase formation in the...
Simple and precise UV spectrophotometric methods by first order derivative and area under curve [AUC] - have been developed and validated for the estimation of carvedilol hydrochloride in bulk and its tablet formulation. The standard...
