Biophotonics and Optical Biosensors
The area under the receiver operating characteristic (ROC) curve is a measure used to evaluate the performance of a binary classification model. It quantifies how well the model can distinguish between two classes by plotting the true positive rate against the false positive rate at various threshold settings. A higher area indicates better model performance, making it a crucial metric in machine learning applications, especially in biosensor data analysis where distinguishing between signals and noise is vital.
congrats on reading the definition of Area Under the Receiver Operating Characteristic Curve. now let's actually learn it.
