摘要:

由于当今网络和应用的快速增长,互联网流量的分类变得越来越重要。网络中连接的数量和新应用程序的增加导致了大量的日志数据,并使专家搜索常见模式变得复杂。在特定类别的应用程序中找到这样的模式对于满足网络分析的各种要求是必要的。深度学习方法在单个系统中从数据中提供特征提取和分类。然而,这些网络非常复杂,并且被用作黑箱模型,这削弱了专家对分类的信任。此外,通过将它们用作黑盒,尽管它们具有出色的性能,但不能从模型预测中获得新的知识。因此,分类的可解释性至关重要。除了增加信任外,解释还可以用于模型评估,从数据中获得新的见解并改进模型。在本文中,我们提出了一个可视化的交互工具,结合了网络数据的分类与解释技术,形成专家,算法和数据之间的接口。

英文摘要:

The classification of internet traffic has become increasingly important due to the rapid growth of today's networks and applications. The number of connections and the addition of new applications in our networks causes a vast amount of log data and complicates the search for common patterns by experts. Finding such patterns among specific classes of applications is necessary to fulfill various requirements in network analytics. Deep learning methods provide both feature extraction and classification from data in a single system. However, these networks are very complex and are used as black-box models, which weakens the experts' trust in the classifications. Moreover, by using them as a black-box, new knowledge cannot be obtained from the model predictions despite their excellent performance. Therefore, the explainability of the classifications is crucial. Besides increasing trust, the explanation can be used for model evaluation gaining new insights from the data and improving the model. In this paper, we present a visual interactive tool that combines the classification of network data with an explanation technique to form an interface between experts, algorithms, and data.
