WebApr 25, 2024 · In this article, I will introduce a real-time anomaly detection scheme using Flink directly. 2. Anomaly detection algorithm. 2.1 types of abnormalities. There are three types of anomalies (outliers): Global outlier, the most basic anomaly, is a single outlier; WebOCI Anomaly Detection provides multiple data processing techniques that account for errors and imperfections in real-world input data, such as from low-resolution sensors. It automatically identifies and fixes data quality issues—resulting in fewer false alarms, better operations, and more accurate results. Custom-trained models
WebApr 1, 2024 · Technically, such operation introduces an additional delay, since it is not natively provided by Flink. Anyway, it ensures a more accurate anomaly detection limiting the number of out of order messages. 3.4.
