WebMar 21, 2024 · AUC for the ROC curve is a performance measurement for classification problems. ROC is a probability curve and AUC represents the degree or measure of separability. The metric ranges from 0 to 1 and indicates how much the model is capable of distinguishing between classes. WebWDA was a robust predictor of lung cancer: random removal of 1/3 of the VOCs did not reduce the AUC of the ROC curve by >10% (99.7% CI). A test employing WDA of breath VOCs predicted lung cancer with accuracy similar to chest computed tomography. The algorithm identified dependencies that were not apparent with traditional linear methods.
