ROC曲线中的optimal threshold roc曲线解释 概述 很多分类器根据测试样本产生一个概率预测,然后将该预测值与阈值进行比较,高于阈值则被分类为正类,低于阈值则被分为负类。 AUC值是评价分类器的一个指标,全称是Area Under Curve,直译就是曲线下的面积。什么曲线呢,就是ROC曲线。 ROC曲线 要介绍AUC值,首先得介绍ROC...
Conclusions The optimal IIR threshold to identify LA ablation scar by dark-blood LGE CMR is 1.09. Because of interpatient variability, the investigators recommend using a lower (1.00) and upper (1.10) threshold to prevent over- or underestimation of ablation scar....

As a special case, if the classifier outputs are well-calibrated conditional probabilities, then the optimal threshold is half the optimal F1 value. As another special case, if the classifier is completely uninformative, then the optimal behavior is to classify all examples as positive. When the ...
Optimal Threshold Policies for Multivariate POMDPs in Radar Resource Management Summary: This paper deals with solving multivariate partially observed Markov decision processes (POMDPs). We give sufficient conditions on the cost functi... V Krishnamurthy - European Conference on Symbolic & Quantitative ...

There was a threshold around five servings of fruits and vegetables a day, after which the risk of all-cause mortality did not reduce further. Boeing et al. summarized the strength of evidence behind fruit and vegetable intake and specific chronic diseases. The conclusions from this work suggest...
Clearly, the average error rate is a function of the detection time ts and the threshold \(\tilde{N}\). To identify the optimal time of detection that minimizes Perr, we follow a two-step procedure, (i) Given ts, the threshold is identified to minimize \({P}_{{\rm{err}}}({t}...
