Anomaly detection is used to identify outliers in data from "summary" of Data Science for Business by Foster Provost,Tom Fawcett
Anomaly detection is a common data mining technique used to identify unusual or rare examples in a dataset. Anomalies, or outliers, are data points that do not conform to the general patterns in the data. These anomalies can be caused by errors in data collection, measurement noise, or actual interesting phenomena that are worth further investigation. Identifying outliers is important in many real-world applications. For example, in fraud detection, anomalies in credit card transactions may indicate potential fraudulent activity. In network security, anomalies in network traffic may indicate a security breach. In manufacturing, anomalies in process data may indicate a faulty machine or process. There are different types of anomaly detection techniques, ranging from simple threshold-based methods to more sophisticated machine learning algorithms. One common approach is to use statistical methods to identify data points that deviate significantly from the norm. Another approach is to use machine learning algorithms, such as clustering or classification, to identify anomalies based on patterns in the data. It is important to note that not all outliers are necessarily anomalies. Some outliers may be legitimate data points that represent interesting and valuable information. Therefore, it is crucial to carefully analyze and interpret the outliers identified by anomaly detection techniques before taking any action.- Anomaly detection is a powerful tool for identifying outliers in data and can help organizations improve decision-making, detect fraud, ensure security, and optimize processes. By accurately identifying anomalies in data, organizations can gain valuable insights and take timely actions to address any issues that may arise.
