In this paper, we develop a decision-theoretic frameworkfor evaluating data mining systems, which employ classification … thatarise from this point of view. The relation between the quality of a data mining system and the amount of investment that … the decision maker is willing to make is formalized. We propose two ways by which independent data mining systems can be …
