Problems solved by technology

Among them, using the number of detectors or statistical inference as the end condition of the algorithm will cause the redundancy of detectors and the "black hole" problem caused by low detector coverage.
At the same time, the sample matching strategy in the real-valued morphological space is mainly based on Euclidean distance or Manhattan distance, and the real-valued detector that maps complex environmental features has a high dimensionality, which will cause the problem of "dimension disaster". The cost increases sharply, so that the detection performance of the system drops sharply

Theneighborhood morphological space artificial immunodetector multi-source generation algorithm uses a neighborhood morphological space, improves a neighborhood negative selection algorithm, and introduces a chaos theory and a genetic algorithm to form the detector multi-source generation algorithm, thereby solving the problems of each algorithm of a detector in a real-value morphological space.

Description

technical field [0001] The invention relates to a multi-source generating algorithm for an artificial immune detector in a neighborhood shape space, and belongs to the technical field of artificial intelligence immune systems. Background technique [0002] Anomaly detection establishes a pattern profile of normal behavior, and current activity is considered anomalous if it violates its rules. Artificial immune system is one of the important branches of artificial intelligence technology. It is an intelligent method that imitates the function of biological immune system. It is widely used in abnormal detection, data mining, machine learning and other fields. The detector is its core set, and its generation, optimization, and detection operations determine the application effect. [0003] At present, the artificial immune system usually converts the problem domain to the real-valued morphological space, but there are many problems in the traditional detector algorithms based ...
