Confidence Intervals for Machine Learning

WebF1-Score (F-measure) is an evaluation metric, that is used to express the performance of the machine learning model (or classifier). It gives the combined information about the precision and recall of a model. This means a high F1-score indicates a high value for both recall and precision. WebThe results were thoroughly analyzed using the true positive rate (TPR), false negative rate (FNR), positive predictive value (PPV), and false discovery rate (FDR) of the developed machine learning model, as presented in Table 4. Equation (2) can be used to compute TPR, FNR, PPV, FDR, and accuracy. port richey to clearwater fl

WebFeb 5, 2015 · The EER is defined as FPR = 1 - PTR = FNR. Thus to get the EER (the actual error rate) you could use the following: EER = fpr [np.nanargmin (np.absolute ( (fnr - fpr)))] as a sanity check the value should be close to EER = fnr [np.nanargmin (np.absolute ( (fnr - fpr)))] since this is an approximation.
