A comparative study of outlier mining and class outlier mining

Abstract

Outliers can significantly affect data mining performance. Outlier mining is an important issue in knowledge discovery and data mining and has attracted increasing interests in recent years. Class outlier is promising research direction. Few researches have been done in this direction. The paper theme has two main goals: the first one is to show the significance of Class Outlier Mining by discussing a comparative study between a Class Outlier detection method called Class Outlier Distance Based (CODB) and a conventional Outlier detection method. The second goal is to introduce
