Algorithms for Spatial Outlier Detection
A spatial outlier is a spatially referenced object whose non-spatial attribute values are significantly different from the values of its neighborhood. Identification of spatial outliers can lead to the discovery of unexpected, interesting, and useful spatial patterns for further analysis. One drawback of existing methods is that normal objects tend to be falsely detected as spatial outliers whe...
متن کاملFast outlier detection using rough sets theory
In many Knowledge Discovery applications, finding outliers is more interesting than finding inliers in a dataset. The perception of outliers is rare cases in dataset in which is being described as abnormal data in the information table. Outliers detections are applied in many important applications like fraud detection systems to uncover the suspicious objects which may have important knowledge...
متن کاملWSO-based Spatial Outlier Detection Algorithms
Based on the idea of Weighted Spatial Outlier (WSO), this study identifies the influences of spatial attributes on the calculation of spatial outlying degree, combines these influences with non-spatial attributes, and proposes two revised spatial outlier detection algorithms, Improved Z-value (IZ-value) algorithm and Weighted Difference Algorithm (WDA). The proposed algorithms are detailed in t...
متن کاملDetecting Significant Alarms using Outlier Detection Algorithms
Although alarms in plants are designed to notify any anomaly or faults in order to prevent accidents or to improve process, it is very difficult for the operators to identify meaningful alarms, since there are large volumes of false and nuisance alarms. Outlier detection algorithms are used to identify anomaly in data, and thus they can be used to suggest abnormal alarms. In this research, we a...
متن کاملApplying Genetic Algorithms to Outlier Detection
Researchers are accustomed to inexactness in physical measurements and have developed statistical methods to help deal with error. Detecting outlying observations in regression data (outliers) is an important step in analysis of these sets of data. This paper presents a genetic algorithm capable of generating subsets for multiple-case outlier diagnostics. The genetic algorithm uses the diagnost...
