Evaluating System Performance: Between a “ROC” and a Hard Place
How can engineers use a receiver operating characteristics curve to assess the functioning of a complex sensor system?
When Emerson wrote, “Build a better mousetrap, and the world will beat a path to your door,” he likely had no idea how complicated that simple idea could become. What constitutes “better” to today’s engineer is often a matrix of conflicting parameters and concerns ranging from functionality to marketing. The engineer must sift through this complexity and decide how well any new device can actually solve a problem.
