Clustering-based outlier detection: Clustering is anunsupervised learningalgorithm. The model is learned based on the organization of the training samples themselves with no label information. The Density-based spatial clustering of applications with noise (DBSCAN) is one of clustering algorithms that ca...
This paper firstly uses the traffic clustering method F-DBSCAN to cluster the unknown protocol traffic. Then an improved CFSM(Closed Frequent Sequence Mining) algorithm is used to mine closed frequent sequences from the messages and identify protocol keywords. Finally, CFGM(Closed Frequent Group ...

Clustering Algorithm In subject area: Mathematics Clustering algorithms aim at investigating in an unsupervised fashion the structure of multivariate data by partitioning them into a finite number of groups based on a chosen (dis-)similarity measure. From: Chemometrics and Intelligent Laboratory Systems,...
The procedure for the DBSCAN clustering algorithm is detailed as follows: Step 1: The algorithm starts with an arbitrary starting data point that has not been visited. The points within the distance “ɛ” are extracted as neighborhood points. Step 2: The clustering process starts with “minPo...
