International Conference on Hybrid Intelligent Systems (HIS)

作者： Dennis Barrios-Aranibar Luiz Marcos Garcia Goncalves Department of Computing Engineering and Automation Federal University of Rio Grande do Norte Natal RN Brazil

In this work authors extend the model of the reinforcement learning paradigm for multi-agent systems called "influence value reinforcement learning " (IVRL). In previous work an algorithm for repetitive games was proposed, and it outperformed traditional paradigms. Here, authors define an algorithm based on this paradigm for using when agents has to learn from delayed rewards, thus, an influence value reinforcement learning algorithm for two agents stochastic games. The IVRLparadigm is based on social interaction of people, specially in the fact that people communicate each other what they think about their actions and this opinion has some influence in the behavior of each other. A modified version of Q-learning algorithm using this paradigm was constructed. The so called TV Q-learning algorithm was implemented and compared with versions of Q-learning for independent learning and joint action learning. Our approach shows to have more probability to converge to an optimal equilibrium than IQ-learning and JAQ-learning algorithms, specially when exploration increases.

Medical problems involve different types of variables and data, which have to be processed, analyzed and synthesized in order to reach a decision and/or conclude to a diagnosis. Usually, information and data set are both symbolic and numeric but most of the well-known data analysis methods deal with only one kind of data. Even when fuzzy approaches are considered, which are not depended on the scales of variables, usually only numeric data is considered. The medical decision support methods usually are accessed in only one type of available data. Thus, sophisticated methods have been proposed such as integrated hybrid learning approaches to process symbolic and numeric data for the decision support tasks. Fuzzy cognitive maps (FCM) is an efficient modelling method, which is based on human knowledge and experience and it can handle with uncertainty and it is constructed by extracted knowledge in the form of fuzzy rules. The FCM model can be enhanced if a fuzzy rule base (IF-THEN rules) is available. This rule base could be derived by a number of machine learning and knowledge extraction methods. Here it is introduced a hybrid attempt to handle situations with different types of available medical and /or clinical data and with difficulty to handle them for decision support tasks using soft computing techniques.

Today, more and more Electronic Control Units have been installed in vehicle, and Controller Area Network is one of the most widely used networks to connect these ECUs, also the architecture of OSEK is increasingly employed into the design of individual ECU and the network. In this paper, we propose a new framework to design the ECU with limited-storage-space. In the framework, an infinite cycle acts as a mainframe, and the code conforming to OSEK NM is inserted into the cycle. A siren of vehicle is developed with this method, and a Hardware-In-Loop test is accomplished. The results show that the framework is available, and the real-time performance of the siren is satisfied. © 2007 IEEE.

This work presents the application of the omni-aiNet algorithm - an immune-inspired algorithm originally developed to solve single and multiobjective optimization problems - to the reconstruction of phylogenetic trees. The main goal of this work is to automatically evolve a population of phylogenetic unrooted trees, possibly with distinct topologies, by minimizing at the same time the minimal evolution and the mean-squared error criteria. The obtained set of phylogenetic trees contains non-dominated individuals that form the Pareto front and that represent the trade-off of the two conflicting objectives. Given this set of phylogenetic trees, two multicriterion decision-making techniques were applied in order to try to select the best solution within the Pareto front.

This paper presents a new approach based on HMM/ANN hybrid for online signature verification. A group of ANNs are used as local probability estimators for an HMM. The Viterbi algorithm is employed to work out the global posterior probability of a model. The proposed HMM/ANN hybrid has a strong discriminant ability, i.e, from a local sense, the ANN can be regarded as an efficient classifier, and from a global sense, the posterior probability is consistent with that of a Bayes classifier. Finally, the experimental results show that this approach is promising and competing.

This paper presents a novel automatic and dynamic camera calibration algorithm based on traffic visual surveillance. The algorithm can automatically calibrate the intrinsic and extrinsic parameters of camera, and offer enough guarantee to extract traffic real-time parameters. This paper firstly indicates the significance of applying automatic and dynamic calibration algorithm to intelligent transportation system, then establishes a mathematical model of calibration parameters between camera image and actual road. The algorithm is established from three view points, which are description, flow chart and algorithm description. Afterward this paper describes the experimental method and result based on this novel algorithm. Finally this paper indicates wide application foreground of this algorithm in intelligent transportation system.

It has been found that some huge overshoot in the sense of sup-norm may be observed when typical iterative learning control (ILC) algorithms are applied to LTI systems, even though monotone convergence in the sense of λ-norm is guaranteed. In this paper, a new ILC algorithm with adjustment of learning interval is proposed to resolve such an undesirable phenomenon, and it is shown that the output error can be monotonically converged to zero in the sense of sup-norm when the proposed ILC algorithm is applied. A numerical example is given to show the effectiveness of the proposed algorithm.

In these last few years, the Internet as it is today has put some limitations on the evolution of new services. Problems such as address space scarcity, mobility, sensor networks and VoIP are becoming common requirements now and will be more frequent in future. However, the current Internet architecture does not support this evolution. In 2003, Jon Crowcroft [1] discussed the problems of the Internet Architecture. In January 2005, a report from NSF [2] addressed the barriers that need to be faced in order to overcome limitations towards a new internetworking architecture. In this paper, we discuss how Web services can be useful in solving some interdomain problems. The strong interaction between ISPs already exists and will be more necessary as new services appear. We believe that the Web services solution is a facilitator in this path. Our discussion is supported by the CANARIE [3] research point of view that everything is a service. We use this idea in the context of interdomain interactions where each domain is then seen as a service. We developed an architecture to support these interactions and evaluated the prototype in terms of time and bandwidth consumption to provide interdomain services.

41st International Conference on Large High Voltage Electric Systems 2006, CIGRE 2006

In the underexcitation quadrant, standard power chart of synchronous generator has its limit defined by practical stability limit and by field current minimum. However, during the time, some generators have shown certain sensitivity during the permanent underexcited operation even in the stabile operating area due to local heating of magnetic conductive parts in the end region of the machine. Underexcited operation is usually required in case of raised network voltage while the active power demands are lowered. Precise knowledge of limits of underexcited operation ability enables precise planning of system reactive power trading. Some world experiences, axial magnetic field measurements, as well as local heating measurements in the end region of synchronous generator are presented. Based on mentioned measurements, it is possible to define real power chart which almost always deviates in capacitive operating area compared to manufacturer's diagram.
