Anomaly Detection in Data Mining: A Review

Abstract

Anomaly detection is the new research topic to this new generation researcher in present time. Anomaly detection is a domain i.e., the key for the upcoming data mining. The term 'data mining' is referred for methods and algorithms that allow extracting and analyzing data so that find rules and patterns describing the characteristic properties of the information. Techniques of data mining can be applied to any type of data to learn more about hidden structures and connections. In the present world, vast amounts of data are kept and transported from one location to another. The data when transported or kept is informed exposed to attack. Though many techniques or applications are available to secure data, ambiguities exist. As a result to analyze data and to determine different type of attack data mining techniques have occurred to make it less open to attack. Anomaly detection is used the techniques of data mining to detect the surprising or unexpected behaviour hidden within data growing the chances of being intruded or attacked. This paper work focuses on Anomaly Detection in Data mining. The main goal is to detect the anomaly in time series data using machine learning techniques.
