In this paper, fuzzy theory has been applied to social network analysis (SNA). Social network analysis models meaningful relations that exist between entities as graph. These entities may be people, events, organizations, symbols in text, sounds in verbalizations, nations of the world and so on. However, the fuzzy graph can be very huge and thus the ability to arrive at meaningful conclusions in a...
In this paper we present a formal model of semantics for cisets, ciset relations and ciset relational operators. The notion of alternate worlds is used to formalize the information content of a ciset and ciset relations. A ciset represents a collection of (regular) sets. Similarly, a ciset relation represents a collection of (regular) relations. Once this collection has been identified, any ciset...
A novel hyperellipsoidal clustering technique is presented for an intrusion-detection system in network security. Hyperellipsoidal clusters toward maximum intracluster similarity and minimum intercluster similarity are generated from training data sets. The novelty of the technique lies in the fact that the parameters needed to construct higher order data models in general multivariate Gaussian functions...
