Distributed Intelligent Network Management Model for the Large-Scale Computer Network
Computer networks have become large-scale distributed systems and network management will develop towards the distributed management and the intelligent management. Multi-agent based Distributed Intelligent Network Management model (MDINM) for the large-scale computer network, which utilizes key characteristics of the agent, such as autonomy, reactivity, and mobility, is put forward in this paper. This model can not only avoid transmitting a large amount of original data on the network to realize the distributed network management but also provides network management with more intelligence by realizing the dynamic self-management for the network. The experimental results show that MDINM is better than the existing network management solutions on performance for the large-scale computer network.

title: Distributed network self-management model based on CSCW
abstract: Computer network system has become a large-scale distributed system. But various kinds of existing network management solutions cannot manage it efficiently and network management is facing the new challenges. Applying the principles of CSCW to network management by multi-agent system is a novel train of thought of constructing the new generation network management system. Distributed network self-management model (DNSM), which is based on multi-agent system, adopts the management policies based on management domain and provides users with Web-based management way, was put forward in this paper. This model not only provides network management with more intelligence but also avoids the usage of amounts of network bandwidth. The experimental results show that DNSM is better than the existing network management solutions on performance for the large-scale computer network.

title: Multi-Space-Mapped SVMs for Multi-class Classification
abstract: In SVMs-based multiple classification, it is not always possible to find an appropriate kernel function to map all the classes from different distribution functions into a feature space where they are linearly separable from each other. This is even worse if the number of classes is very large. As a result, the classification accuracy is not as good as expected. In order to improve the performance of SVMs-based multi-classifiers, this paper proposes a method, named multi-space-mapped SVMs, to map the classes into different feature spaces and then classify them. The proposed method reduces the requirements for the kernel function. Substantial experiments have been conducted on one-against-all, one-against-one, FSVM, DDAG algorithms and our algorithm using six UCI data sets. The statistical results show that the proposed method has a higher probability of finding appropriate kernel functions than traditional methods and outperforms others.

title: Analog circuit optimization system based on hybrid evolutionary algorithms
abstract: This paper investigates a hybrid evolutionary-based design system for automated sizing of analog integrated circuits (ICs). A new algorithm, called competitive co-evolutionary differential evolution (CODE), is proposed to design analog ICs with practical user-defined specifications. On the basis of the combination of HSPICE and MATLAB, the system links circuit performances, evaluated through electrical simulation, to the optimization system in the MATLAB environment, once a circuit topology is selected. The system has been tested by typical and hard-to-design cases, such as complex analog blocks with stringent design requirements. The results show that the design specifications are closely met, even in highly-constrained situations. Comparisons with available methods like genetic algorithms and differential evolution, which use static penalty functions to handle design constraints, have also been carried out, showing that the proposed algorithm offers important advantages in terms of optimization quality and robustness. Moreover, the algorithm is shown to be efficient.

title: Multi-agent System for Custom Relationship Management with SVMs Tool
abstract: Distributed data mining in the CRM is to learn available knowledge from the customer relationship so as to instruct the strategic behavior. In order to resolve the CRM in distributed data mining, this paper proposes the architecture of distributed data mining for CRM, and then utilizes the support vector machine tool to separate the customs into several classes and manage them. In the end, the practical experiments about one Chinese company are conducted to show the good performance of the proposed approach.

title: Towards the SocioScope: an information system for the study of social dynamics through digital traces
abstract: Over the past decade there has been an explosion in the deployment of pervasive systems like cell phone networks and content aggregators on the Internet that produce massive amounts of data as by-products of their interaction with users. This data is related to the actions and opinions of people and thereby to the overall dynamics of cities, how they function and evolve over time.
 Here we propose the implementation of a new information system, the SocioScope, that streamlines the operations of data gathering and data storage and that supports the diverse needs of the research community, local authorities, enterprises, and citizens. Our SocioScope allows for the collection, integration, and study of different types of spatiotemporal data.
 We present two use cases and an analysis of the requirements for the system. We introduce the multi-tier architecture that supports data gathering, storage, integration, analysis, and visualization. We describe the technical implementation of each module of the system and of the security mechanism for data access control. We conclude with a discussion on the opportunities and challenges of the study of digital traces and with an brief illustration of future directions of work.

title: Neural Network Identification Method Applied to the Nonlinear System
abstract: A kind of neural network solution method has been proposed in the paper aiming at a class of non-linear process control system with the characteristic of time delay. In this scheme, a new-type associative memory neural network is used to model the controlled system, and the fuzzy neural network with inverse identification structure is adopted to control the nonlinear process system. This fuzzy neural network control method adopts the structure of three layers combine neural network identifier with inverse structure. Computer simulation and lab application show that it is effective to adopt this scheme to control on-linear process system with time delay.
