4997 孤立森林算法是基于隔离机制的异常检测算法,存在与轴平行的局部异常点无法检测、对高维数据异常点缺乏敏感性和稳定性等问题。 The isolation-based anomaly detector, isolation forest has two weaknesses, its inability to detect anomalies thatwere masked by axis-parallel clusters, and anomalies in high-dimensional data.
4998 针对这些问题,提出了基于随机超平面的隔离机制和多粒度扫描机制,随机超平面使用多个维度的线性组合简化数据模型的隔离边界,利用随机线性分类器的隔离边界能够检测更复杂的数据模式。 An isolation mechanism based on random hyperplane and a multi-grained scanning was proposed to overcome these weaknesses. The random hyperplane generatedby a linear combination of multiple dimensions was used to simplify the isolation boundary of the data model which was a random linear classifier that can detect more complex data patterns, so that the isolation mechanism was more consis-tent with data distribution characteristics.

5001 为解决广域信息管理(SWIM)服务提供者由于自身故障或受到恶意攻击,造成 SWIM 服务中断、服务时延增加或服务质量下降的问题,提出了一种基于态势感知的 SWIM 服务权限主动移交模型,利用随机森林算法判别 SWIM 服务提供者安全态势,依据安全态势主动移交 SWIM 服务权限,降低突发事件对 SWIM 服务的影响。 To solve the problem that in the system wide information management (SWIM) network, the SWIM serviceprovider suffers from SWIM service interruption, service delay increase or service quality degradation due to maliciousattack or self-failure. Therefore, a proactive migration model of SWIM service was proposed on the basis of situationawareness, which used the random forest algorithm to timely judge the SWIM service provider security situation. SWIMservice authority was actively migrated according to security situation, and the emergencies impact on SWIM serviceswere reduces.
