Understanding Artificial Immune Systems (AIS)
Artificial Immune Systems, as the name suggests, mimic the behavior of the human immune system to address challenges such as anomaly detection, pattern recognition, optimization, and classification. The human immune system protects the body from harmful invaders through a process of recognition, response, and memory. AIS aims to replicate this process using computational models and algorithms.
Biologically Based AI Techniques

In AI, CSA is used for optimization and search tasks. It begins with a population of antibodies and evolves them through mutation and selection to find the best solution.
- Negative Selection Algorithm (NSA): NSA is rooted in the concept of self versus non-self recognition in the immune system. In AI, NSA is used for anomaly detection and intrusion detection systems. It generates a set of detectors (antibodies) to recognize normal behavior patterns, and any deviation is considered an anomaly.
- Artificial Immune Network (AIN): AIN models the interactions between different components of the immune system, such as antibodies and T-cells. It is applied in classification and pattern recognition tasks, where antibodies represent data patterns, and T-cells act as classifiers.
