Trajectory priming with dynamic fuzzy networks in nonlinear optimal control
(IEEE-Inst Electrical Electronics Engineers Inc, 2004)Fuzzy logic systems have been recognized as a robust and attractive alternative to some classical control methods. The application of classical fuzzy logic (FL) technology to dynamic system control has been constrained by ... -
Modeling and prediction with a class of time delay dynamic neural networks
(Elsevier Science BV, 2007)In this paper, we propose a time delay dynamic neural network (TDDNN) to track and predict a chaotic time series systems. The application of artificial neural networks to dynamical systems has been constrained by the ... -
Hybrid feature selection for text classification
(Tubitak Scientific & Technical Research Council Turkey, 2012)Feature selection is vital in the field of pattern classification due to accuracy and processing time considerations. The selection of proper features is of greater importance when the initial feature set is considerably ... -
Phase portrait modeling of a nonlinear system with a dynamic fuzzy network
(Springer, 2005)Fuzzy logic and neural networks are two important technologies for modeling and control of dynamical systems and have been constrained by the non-dynamical nature of their some popular architectures. There exist problems ... -
Modified descend curvature based fixed form fuzzy optimal control of nonlinear dynamical systems
(Pergamon-Elsevier Science LTD, 2006)In this study, a fuzzy rule-based optimal controller is designed for nonlinear dynamical systems. The direct second order method (or direct-descend-curvature algorithm) with a modification called "modified descend controller ... -
Privacy-Preserving Concordance-based Recommendations on Vertically Distributed Data
(IEEE, 2012)Recommender systems are attractive components of e-commerce. Customers apply such systems to get help for choosing the appropriate product to purchase. To provide accurate and dependable referrals, recommender systems ... -
Time delay dynamic fuzzy networks for time series prediction
(Springer-Verlag Berlin, 2005)This paper proposes a Time Delay Dynamic Fuzzy Network (TDDFN) that can be used for tracking and prediction of chaotic time series. TDDFN considered here has unconstrained connectivity and dynamical elements in its fuzzy ... -
Unique subnet auto-configuration in IPv6 networks
(Springer-Verlag Berlin, 2006)IPv6 host auto-configuration has been part of IPv6 specification from the start, but IPv6 routers still require manual configuration and administration. This is not only unacceptable for emerging home and SOHO networks, ... -
A multi-camera vision system for real-time tracking of parcels moving on a conveyor belt
(Springer-Verlag Berlin, 2005)We consider the problem of designing a vision system for tracking parcels moving on a conveyor belt. After computing parcels dimensions, i.e., length, width and height, at the entrance of the conveyor belt using a stereo ... -
