In this tutorial, you will discover ROC Curves, Precision-Recall Curves, and when to use each to interpret the prediction of probabilities for binary classification problems. After completing this tutorial, you will know: ROC Curves summarize the trade-off between the true positive rate and false...

In this case, float data type had to be used (see Section 2.2). So, accuracy and precision were of course perfect, since there are no false or true negative or false positive results in exact algorithms. A further analysis (e.g. ROC curves, precision-recall) like in many fields of ...
Both curves provide graphically standard tools to evaluate the performance of a binary classifier as its discrimination threshold is varied. While the ROC curve uses the ratio of Detection Rate (DR) to False Alarm Rate (FAR), the PR curve utilize the ratio of precision to recall therefore ...
off'' value from 0 (all negatives) to a maximum value (all positives), we obtain the ROC by plotting TPR (true positive rate also called sensitivity) versus FPR (false positive also called specificity) across varying cut-offs, which generate a curve in the unit square called an ROC curve...

This conclusion is further supported by the ROC curves of Fig. 12 and the associated AUC values (see the legend of Fig. 12). These curves confirm, indeed, that the LS-CycleGAN model combined with the Jensen-Shannon distance metric (resp., the LS-BiGAN model combined with the Correlation ...
Step 2The second step is to generatenodevectors in ASTs. In this step, each node in ASTs is trained and map to a real-valued vector, which contains each feature of the node. Inspired by BigCodetools19, the Skip-gram model20is used to computenodevectors. The principle of this model is...
In particular, we provide an information theoretic evaluation of the cases where (i) the RNG has a small bias, and (ii) a counter was used to generate equally likely but predictable outputs. This evaluation naturally suggests that uniform randomness is a strong requirement for the security of ...
