Hilas, Constantinos S.; Mastorocostas, Paris A. (2008-10)This paper investigates the usefulness of applying different learning approaches to a problem of telecommunications fraud detection. Five different user models are compared by means of both supervised and unsupervised ...

Mastorocostas, Paris A.; Hilas, Constantinos S. (2009-10-01)A recurrent fuzzy neural network with internal feedback is suggested in this paper. The network is entitled dynamic block-diagonal fuzzy neural network (DBD-FNN), and constitutes a generalized Takagi-Sugeno-Kang fuzzy ...

Hilas, Constantinos S.; Mastorocostas, Paris A.; Rekanos, Ioannis T. (2015-07-01)A user’s transactions with modern networks and services produce a vast amount of user related data. The byproduct of every phone call a person makes or every web page one visits is translated into a log record with usage ...

Mastorocostas, Paris A.; Theocharis, John B. (2007-01-01)This paper presents a recurrent filter that performs real-time separation of discontinuous adventitious sounds from vesicular sounds. The filter uses two Dynamic Fuzzy Neural Networks, operating in parallel, to perform the ...

Hilas, Constantinos S.; Kazarlis, Spyridon A.; Rekanos, Ioannis T.; Mastorocostas, Paris A. (2014-03)Telecommunications fraud has drawn the researchers’ attention due to the huge economic burden on companies and to the interesting aspect of users’ behavior modeling. In the present paper, an application of genetic ...

Mastorocostas, Paris A.; Varsamis, Dimitris N.; Mastorocostas, Costas A.; Hilas, Costas S. (2007)This paper presents a locally recurrent globally feedforward fuzzy neural network, with internal feedback, that performs the task of separation of lung sounds, obtained from patients with pulmonary pathology. The filter ...

Mastorocostas, Paris A.; Stavrakoudis, Dimitris; Theoharis, John (2008-12)This paper presents a recurrent fuzzy-neural filter that performs the task of separation of lung sounds, obtained from patients with pulmonary pathology. The filter is a pipelined Takagi–Sugeno–Kang recurrent fuzzy network, ...

Mastorocostas, Paris A.; Varsamis, Dimitris N.; Mastorocostas, Constantinos A.; Hilas, Constantinos S. (2006)This paper presents a dynamic neural filter for adaptive noise cancellation. The cancellation task is transformed to a system-identification problem, which is tackled by use of the Block-Diagonal Recurrent Neural Network. ...
-
Mastorocostas, Paris A.; Hilas, Constantinos S. (2012-01-21)In this work, a dynamic neurofuzzy system for forecasting outgoing telephone calls in a University Campus is proposed. The system comprises modified Takagi–Sugeno–Kang fuzzy rules, where the rules’ consequent parts are ...
-
Mastorocostas, Paris A.; Hilas, Constantinos S. (2014)An application of fuzzy modeling to the problem of telecommunications time-series prediction is proposed in this paper. The model building process is a two-stage sequential algorithm, based on Subtractive Clustering (SC) ...
-
Mastorocostas, Paris A.; Hilas, Constantinos S. (2011-05)In this work a dynamic neuro-fuzzy network (DyNF-Net) is proposed, which is applied on the outgoing telephone traffic of a large organization. It is a modified Takagi-Sugeno-Kang fuzzy neural network, where the consequent ...
