Anomaly detection refers to methods that provide warnings of unusual behaviors which may compromise the security and performance of communication networks. In this paper it is proposed a novel model for network anomaly detection combining baseline, K-means clustering and particle swarm optimization (PSO...
人工智能23-作业四-KMeans 实现异常点检测1.实验介绍1.1 实验背景 异常值检测(outlier detection )是一种数据挖掘过程,用于发现数据集中的异常值并确定异常值的详细信息。 当前数据容量大、数据类型多样、获取数据速度快;但是数据也比较复杂,数据的质量有待商榷;而数据容量大意味着手动标记异常值成本高、效率低下;因...
