异常检测(Anomaly Detection)方法与Python实现 异常检测(Anomaly detection)是机器学习的常见应用,其目标是识别数据集中的异常或不寻常模式。尽管通常被归类为非监督学习问题,异常检测却具有与监督学习相似的特征。在异常检测中,我们通常处理的是未标记的数据,即没有明确的标签指示哪些样本是异常的。相反,算法需要根据数据...
Deep learning for unsupervised insider threat detection in structured cybersecurity data streams. arXiv preprint arXiv:1710.00811, 2017. 六、基于训练对象的模型 按照训练对象的区别,我们把训练模型单独划分为两类,变种模型与单分类神经网络。 1. 深度变种模型Deep Hybrid Models(DHM) Jerone TA Andrews, Edward...
