The respective chapters highlight the latest developments in k-nearest neighbor-based outlier detection research and cover such topics as our present understanding of unsupervised outlier detection in general; distance-based and density-based outlier detection in particular; and the applications of the latest findings to boundary point detection and novel object detection. The book also offers a new perspective on bridging the gap between k-nearest neighbor-based outlier detection and clustering-based outlier detection, laying the groundwork for future advances in unsupervised outlier detection research. The authors hope the algorithms and applications proposed here will serve as valuable resources for outlier detection researchers for years to come. 606 $aData mining 606 $aOutliers (Statistics) 615 0$aData mining. 615 0$aOutliers (Statistics) 676 $a006.312 700 $aWang$b Xiaochun$01225159 702 $aWang$b Xiali 702 $aWilkes$b Mitch 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bUtOrBLW 906 $aBOOK 912 $a9910483597703321 996 $aNew developments in unsupervised outlier detection$92844686 997 $aUNINA
