2.1 Anomaly Detection Anomaly or outlier detection is the detection of points in a data set that are di erent from all other ormal" points [1]. It is often used in tasks such as intrusion detection (in cyber-security), fault detection in various types of systems and military surveillance. There are six types of techniques used
PyOD is a comprehensive and scalable Python toolkit for detecting outlying objects in multivariate data. This exciting yet challenging field is commonly referred as Outlier Detection or Anomaly Detection. PyOD includes more than 30 detection algorithms, from classical LOF (SIGMOD 2000) to the latest COPOD (ICDM 2020).
