A General Method for Making Classifiers Cost Sensitive . In Proceedings of the Fifth International Conference on Knowledge Discovery and Data Mining, pp. Section 2 examines the major cost factors related to IDSs, and the problem of modeling and measuring the relationship among these factors. The IDS responds to a detected intrusion if and only if the damage cost is greater than the response cost. A general method for making classifiers cost-sensitive .
Some classifiers have parameters for which different settings produce different ROC points.
Plotting all the ROC points that can be produced by varying these parameters produces an ROC curve for the classifier. If point A dominates point B, A it will have a lower expected cost than B for all possible cost ratios and class distributions. A general method for making classifiers cost-sensitive . This gives us a cost sensitive classification procedure whose performance relies on the accuracy of the computed class probability estimates. A general method for making classifiers cost-sensitive .
