Event Correlation and Pattern Recognition
1. Event Correlation
Correlation of events implies the correlation of events specifically means identifying and analysing relationships between several events in order to derive the right form of insights or make even some improvements. Here’s how event correlation works:
- Temporal Correlation: Events that happen within a defined time and space may be correlated with each other in such a way that they can be used to establish causality or dependency.
- Spatial Correlation: The coordinates of events sourced from different regions or places can be used to pinpoint their spatial intersection (if there actually exists any).
- Attribute-based Correlation: Grouping activities that have similar features or metadata may improves their association and the detection of related patterns.
2. Pattern Recognition
Pattern recognition contains the detection and analysis of repetitions, trends or weirdnesses within streaming event data. Here are key aspects of pattern recognition in CEP systems:
- Sequential Pattern Detection: CEP systems are designed to scan through the event logs which are aimed to detect repeated events or event patterns in real time. Such scenarios can embody all possibilities of a user flowing through the system, performing the operations or workflows.
- Anomaly Detection: CEP system is based on the use of areas of statistics, machine learning algorithm or predetermined thresholds to identify deviation from normal way of behavior or from the expected patterns.
- Complex Event Pattern Matching: CEP systems accommodate pattern matching approach that is based on definitions which are the combinations of primitive events coupled with logical operators.
Complex Event Processing (CEP) – System Design
Complex Event Processing (CEP) and other types of technology are changing how we analyze real-time data, gathering, and analyzing on the spot for timely decisions. What CEP systems then do is to detect and evaluate time-series data that not only is mobile and ever-changing, but that exists in large volumes as well, ultimately permitting its users to visualize and comprehend otherwise hidden information.
