Graph-based anomaly detection (GBAD) approaches are among the most popular techniques used to analyze connectivity patterns in communication networks and identify suspicious behaviors. Given the different GBAD approaches proposed for fraud detection, in this study, we develop a framework to synthesize ...
一是不同传感器之间有着非常不同的行为,即图中节点的数值和分布差异很大,因此需要考虑如何对传感器,即图中节点进行特征表示;二是GNNs的输入必须是整个图,即包括图中节点的特征表示以及各节点的连接关系,而在本文场景中,各节点之间的关系都是未知的(以往的方法是直接认为各节点之间都存在关系,即使用完全图表征各节点...
(2015)Graph-based Anomaly Detection and Description : A survey 论文笔记,程序员大本营,技术文章内容聚合第一站。
回顾了异常检测(Anomaly Detection)、多元时间序列数据模型 (models for multivariate time series data)、图神经网络(Graph neural network)的研究相关工作,并指出其不足。 2.1 异常检测(Anomaly Detection) 目的是检测出偏离大部分数据的异常样本,经典方法包括基于密度的研究方法、基于线性模型的研究方法、基于距离的研究...
1. Anomaly Detection In intrusion detection 0x1:入侵检测中的主要建模思路 笔者基于有限的项目经验总结认为,在一般的情况下,要保证在多机器集群中追求入侵检测的AUC(recall和precision的平衡),可以从几个方面切入思考: 1. Misuse Detection 误用检测 这是最经常使用的,也是效果非常不错的一种入侵检测思路,误用这个...
For industrial big data, anomaly detection for multivariate time series data is of critical strategic significance. However, the complexity of industrial e
maritime surveillance;anomaly detection;ship tracking 1. Introduction Ship traffic has increased as the world emerges from the COVID-19 pandemic, leading to a surge in global maritime activities. This escalation in ship movements underscores the importance of preemptively identifying abnormal ship movement...
