A Survey on Cluster Based Outlier Detection Techniques in Data StreamIIRindia
In recent days, Data Mining (DM) is an emerging area of computational intelligence that provides new techniques, algorithms and tools for processing large volumes of data. Clustering is the most popular data mining technique today. Clustering used to separate a dataset into groups that finds intra-group similarity and inter-group similarity. Outlier detection (Anomaly) is to find small groups of data objects that are different when compared with rest of data. The outlier detection is an essential part of mining in data stream. Data Stream (DS) used to mine continuous arrival of high speed data Items. It plays an important role in the fields of telecommunication services, E-Commerce, Tracking customer behaviors and Medical analysis. Detecting outliers over data stream is an active research area. This survey presents the overview of fundamental outlier detection approaches and various types of outlier detection methods in data stream.
Multiple Linear Regression Models in Outlier Detection IJORCS
Identifying anomalous values in the real-world database is important both for improving the quality of original data and for reducing the impact of anomalous values in the process of knowledge discovery in databases. Such anomalous values give useful information to the data analyst in discovering useful patterns. Through isolation, these data may be separated and analyzed. The analysis of outliers and influential points is an important step of the regression diagnostics. In this paper, our aim is to detect the points which are very different from the others points. They do not seem to belong to a particular population and behave differently. If these influential points are to be removed it will lead to a different model. Distinction between these points is not always obvious and clear. Hence several indicators are used for identifying and analyzing outliers. Existing methods of outlier detection are based on manual inspection of graphically represented data. In this paper, we present a new approach in automating the process of detecting and isolating outliers. Impact of anomalous values on the dataset has been established by using two indicators DFFITS and Cook’sD. The process is based on modeling the human perception of exceptional values by using multiple linear regression analysis.
Outlier Detection Using Unsupervised Learning on High Dimensional DataIJERA Editor
The outliers in data mining can be detected using semi-supervised and unsupervised methods. Outlier
detection in high dimensional data faces various challenges from curse of dimensionality. It means due
to the distance concentration the data becomes unobvious in high dimensional data. Using outlier
detection techniques, the distance base methods are used to detect outliers and label all the points as
good outliers. In high dimensional data to detect outliers effectively, we use unsupervised learning
methods like IQR, KNN with Anti hub.

AN IMPROVED FRAMEWORK FOR OUTLIER PERIODIC PATTERN DETECTION IN TIME SERIES U...ijiert bestjournal
Periodic pattern detection in time-series is one of the most important data mining task. The periodici ty detection of an outlier patterns might be more important than the periodici ty of regular,more frequent patterns means periodi c pattern .periodic patterns means Patterns which repeat over a period of time. Pattern those which occur unusually or surprisingly called as Outlier Pattern. In this paper,we present the development of a enha nced spatio-temporal algorithm capable of detecting the periodicity of outlier patterns in a time series using Walmart transaction data and MAD (Median Absolute Deviation) is presen ted. mean valuesis used in existing algorithm which is not efficient. We ha ve to use MAD which increases the output of these a lgorithms and gives more accurate information.
Outlier Detection in Data Mining An Essential Component of Semiconductor Manu...yieldWerx Semiconductor
Outlier detection is a critical research field within data mining due to its vast range of applications including fraud detection, cybersecurity, health diagnostics, and significantly for the semiconductor manufacturing industry. It refers to identifying data points that significantly deviate from expected patterns, providing crucial insights into different aspects of data. However, the ambiguity between outliers and normal behavior, evolving definitions of 'normal', application-specific techniques, and noisy data mimicking outliers, often complicate the outlier detection process. This review article offers an in-depth analysis of the most advanced outlier detection methods, presenting a thorough understanding of future research prospects.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

2. What are outliers? Very often, there exist data objects that do not comply with the general behavior or model of the data. Such data objects, which are grossly different from or inconsistent with the remaining set of data, are called outliers.
3. What is Outlier Analysis? The outliers may be of particular interest, such as in the case of fraud detection, where outliers may indicate fraudulent activity. Thus, outlier detection and analysis is an interesting data mining task, referred to as outlier mining or outlier analysis.
4. Statistical Distribution-Based Outlier Detection Two basic types of procedures for detecting outliers: Block procedures: In this case, either all of the suspect objects are treated as outliersor all of them are accepted as consistent. Consecutive (or sequential) procedures: An example of such a procedure is the insideoutprocedure.
5. Distance-Based Outlier Detection Some efficient algorithms for mining distance-based outliers are as follows: Index-based algorithm Nested-loop algorithm: Cell-based algorithm Density-Based Local Outlier Detection Deviation-Based Outlier Detection with Sequential Exception Technique
6. OLAP Data Cube Technique An OLAP approach to deviation detection uses data cubes to identify regions of anomaliesin large multidimensional data
