This article investigates the properties of class-switching ensembles composed of neural networks and compares them to class-switching ensembles of decision trees and to standard ensemble learning methods, such as bagging and boosting. In a class-switching ensemble, each learner is constructed using a modified version of the training data. This modification consists in switching the class label...

The data transmission by high-speed optical networks has upward trend. Various techniques of multiplexing are used in optical communication networks to satisfy growing demands. Wavelength division multiplexing is currently mostly used multiplex method due to its great advantages. Since the current optical communication networks are based on internet protocol, the optical burst switching present...

Switching dynamics among saddles in a network of nonlinear oscillators can be exploited for information encoding and processing (hence computing), but stable attractors in the system can terminate the switching behavior. An effective control strategy is presented to sustain switching dynamics in networks of pulse-coupled oscillators. The support for the switching behavior is a set of saddles, o...

A model or hybrid network consisting of oscillatory cells interconnected by inhibitory and electrical synapses may express different stable activity patterns without any change of network topology or parameters, and switching between the patterns can be induced by specific transient signals. However, little is known of properties of such signals. In the present study, we employ numerical simula...

In this report, we present a fast switching network protocol for a distributed switching two-way interactive CATV system. The backbone network protocol takes advantage of the tree topology of the CATV network to reduce the processing time and memory requirements at the intermediate nodes. Backbone virtual circuit switching is assumed. The concept of fixed hierarchical logical channel number is ...

The article tackles the problem of quality of service assurance in photonic networks. The idea of multi-service photonic network model with the coexistence of optical circuit and packet switching mechanisms and cell communication is used as a basis for service differentiation in the optical domain. Cell loss ratio as a key performance indicator determines the required optical switching mechanis...

In this paper, we propose a hybrid network architecture, called Content-based Switching Network (CSN), and its signaling scheme, which addresses the issues inherent to conventional hybrid networks which implement a horizontal separation over the entire network (from edge to edge). We will show how CSN nodes can flexibly choose their switching paradigm (store-and-forward, optical bypass, electri...

This paper deals with the comparison between two resource reservation techniques, named Tell and Go (TG) and Tell and Wait (TW), when they are used in an All Optical Network for the support of high-speed IP traffic. This comparison study is motivated considering that the modes currently under investigation for the implementation of the next generation coarse packet switched optical networks, e....

In this paper a zero voltage switched active network (Fig. 1) which can be used in conjunction with single-phase or three-phase ac to dc diode rectifiers is presented. It is shown that application of the proposed switching network in threephase ac to dc boost converter yields zero switching losses while maintaining a unity input power factor. Active network capacitor, Cs, diodes D7, and D8, mai...
