A Review of Methods for Detecting Point Anomalies on Numerical Dataset
Ming Xin Zhao, Jingchao Chen · 2020 IEEE 4th Information Technology, Networking, Electronic and Automation Control Conference (ITNEC) · 2020
Due to the fast development of anomaly detection techniques and its widely application fields, we attempt to provide a clear structure about the newly methods for detecting point anomaly in relative low dimensional numerical datasets. Firstly, we have reviewed recent advancements in three aspects including classification-based anomaly detection techniques, nearest-neighbor-based anomaly detection techniques and clustering-based anomaly detection techniques. Especially we make a detail survey about clustering-based anomaly detection techniques.
