WebArea under Curve (AUC) or Receiver operating characteristic (ROC) curve is used to evaluate and compare the performance of binary classification model. It measures discrimination power of your predictive classification model. In simple words, it checks how well model is able to distinguish (separates) events and non-events. WebThis methodology was tested using 3D tracks generated from mosquito mating swarms in the field and obtained a balanced accuracy of 64.5% and an ROC AUC score of 68.4%. Such a system can be used in a wide variety of trajectory domains to detect and analyse the behaviours of different classes, e.g., sex, strain, and species.

WebThe ROC curves graph sensitivity (or true positive rate [TPR]) against (1-specificity) (or false positive rate [FPR]), where each point is derived from a different threshold.
