Outlier Detection Technique for Univariate Normal Datasets

چکیده
This paper presents an outlier detection technique for univariate normal datasets. Outliers are observations that lips abnormal distance from the mean. Outlier is a useful in such areas as fraud detection, financial analysis, health monitoring and Statistical modelling. Many recent approaches detect outliers according to reasonable, pre-defined concepts of outlier. Methods Gaussian method have been widely used data-sets, however, methods use measure central tendency dispersion affected by hence making be less robust towards outliers. The study aimed at providing alternative can data sets deploying measures variation least (median geometric variation). formulated formula using median then applied formulation on randomly simulated dataset with recorded number detected comparison other two existing best detection. compared sensitivity three simulation was done different ways, first considered mean constant standard deviation while second test held varying deviation. performed best, eliminating most required techniques when there also established stricter varied but still stands out defined relative not more sensitive than Method well technique. In conclusion, could employed detections data-sets it almost same data-sets.

Robust Outlier Detection Technique in Data Mining: A Univariate Approach
Outliers are the points which are different from or inconsistent with the rest of the data. They can be novel, new, abnormal, unusual or noisy information. Outliers are sometimes more interesting than the majority of the data. The main challenges of outlier detection with the increasing complexity, size and variety of datasets, are how to catch similar outliers as a group, and how to evaluate t...
متن کاملStatistical Outlier Detection in Large Multivariate Datasets
This work focuses on detecting outliers within large and very large datasets using a computationally efficient procedure. The algorithm uses Tukey’s biweight function applied on the dataset to filter out the effects of extreme values for obtaining appropriate location and scale estimates. Robust Mahalanobis distances for all data points are calculated using these location and scale estimates. A...
متن کاملAutomatic Outlier Detection in Music Genre Datasets
Outlier detection, also known as anomaly detection, is an important topic that has been studied for decades. An outlier detection system is able to identify anomalies in a dataset and thus improve data integrity by removing the detected outliers. It has been successfully applied to different types of data in various fields such as cyber-security, finance, and transportation. In the field of Mus...
متن کاملEfficient Classification Technique for Outlier Detection
Outliers are the data objects that clearly differ in their behavior from the normal data. Outlier detection mainly aims at finding these data objects. Outlier detection has become the major area of research in data mining. This plays a crucial role in data mining. Most of the methods used for outlier detection, consider the positive data and their behavior, and then the data violating the behav...
متن کاملSpatio-Temporal Outlier Detection Technique
Outlier detection is very important functionality of data mining, it has enormous applications. This paper proposes a clustering based approach for outlier detection using spatio-temporal data. It uses three step approach to detect spatiotemporal outliers. In the first step of outlier detection, clustering is performed on the spatio-temporal dataset with proposed Spatio-Temporal Shared Nearest ...
