System, method and article of manufacture for using receiver operating curves to evaluate predictive utility |
摘要 |
An electronic information system is provided for determining predictive utility of prediction techniques in ascertaining which items are valued. The information system includes an input mechanism for obtaining a set of measurements of actual value of items presented to a user. The items presented to the user are derived from a plurality of items by utilizing predictions from a prediction technique. A processor is operatively coupled to the input mechanism to generate a quality metric receiver operating curve (ROC) from the set of measurements which corresponds to a measure of effectiveness of the prediction technique in predicting which items are valued by the user. In addition, a method is provided for operating this electronic information system. Also, a storage device readable by a computer system for implementing this method is provided.
