survey of clustering and outlier detection techniques in data mining a research perspective





The 2010 SIAM International Conference on Data Mining. Outlier Detection Techniques. Accuracy of outlier detection depends on how good the clustering algorithm captures the structure of clusters. This paper focuses to clarify the problem with detecting outlier over data stream and specific techniques used for detecting outlier over streaming data in data mining. Also this study is focusing on outlier detection techniques and recent research on outlier analysis. Outlier detection is a primary step in many data-mining applications. We present several methods for outlier detection, while distinguishing between univariate vs. multivariate techniques andOutlier detection for data mining is often based on distance measures, clustering and spatial methods. The data mining techniques in this section represent the most often used techniques that have been developed over the last two decades of research.Neural Networks for Outlier Analysis. Sometimes clustering is performed not so much to keep records together as to make it easier to see when one In this paper, we introduce a survey of contemporary techniques for outlier detection.A Robust Outlier Detection Scheme in Large Data Sets, 6th Pacific-Asia Conference on Knowledge Discovery and Data Mining, Taipei, Taiwan, May, 2002.Google Scholar.

Data mining techniques can be grouped in four main categories: clustering, classification, dependency detection, and outlier detection. Clustering is the process of partitioning a set of objects into homogeneous groups, or clusters. We describe an outlier detection methodology which is based on hierarchical clustering methods.As we have mentioned in Section 2.2 the INTRASTAT data was already explored using several data mining techniques.

Clustering, Classification and Outlier Detection. We will study techniques for outlier detection in streams in Section 3. Often times, data is distributed across multiple locations.While a detailed exposition is beyond the scope of this survey, we will provide an overview of the key ideas in this topic, especially from a computer science perspective. In the clustering processes, outliers can affect the locations of the cluster centers, even aggregating as a micro-cluster.Chandola, V. and Banerjee, A. and Kumar, V.

Pottenger, Soma Roy, andMoreover, because the distance between outliers and all clusters is close to the maximal value of 1, if they happen to get assigned to any one of the clusters. At this point, data mining professionals (with a computer science background) are much more actively involved in this area as compared to statisticians. This seems to be a major change in the research landscape. This book presents outlier detection from an integrated perspective Various smoothing techniques, such as bin-ning methods, clustering and outlier detection, have been used in data mining literature to remove noise. Binning methods smooth a sorted data value by consulting the values around it. Keywords: Data mining, clustering, DBSCAN, outlier, LOF algorithm. 1.
