ROC (Receiver Operating Characteristic) curves are graphical representations that illustrate the diagnostic ability of a binary classifier system as its discrimination threshold is varied. They plot the true positive rate against the false positive rate at various threshold settings, helping to visualize the trade-off between sensitivity and specificity. In bioengineering signal processing, ROC curves are crucial for evaluating the performance of diagnostic tests and algorithms, especially as technology evolves and the need for accurate medical decisions grows.
congrats on reading the definition of ROC Curves. now let's actually learn it.
