Pub Date : 2009-11-13 DOI: 10.1109/NCM.2009.148

The rigidity and expectational model is one of the geometric lag models which may cause problems of parameters estimation. In order to consistently estimate the model’s parameters in the ML approach, we propose an easy-to-compute procedure. This new procedure makes the polynomials in the lag operator to be fractionally integrated. A parsimonious model will be obtained when this proposed procedure is applied. And it also will be applied to very general specifications of the error term. In this paper, we employ this new procedure to analyze U.S. consumption function, and then we discuss some interesting results.
刚性期望模型是一种会引起参数估计问题的几何滞后模型。为了在机器学习方法中一致地估计模型的参数,我们提出了一个易于计算的过程。这种新方法使得滞后算子中的多项式是分数积分的。应用该方法可得到一个简洁的模型。它也可以应用到误差项的一般描述中。在本文中,我们使用这个新方法来分析美国的消费函数,然后讨论一些有趣的结果。

Hua Jiang, GuiLin Xu, Zhenrong Deng
In the process of solving multi-objective Pareto solution, the search ability in total area and the convergence characteristics can be reinforced by self-adjusting of aberrance probability in offspring evolution. Comparing with the typical hybrid genetic algorithm, the more effective optimization convergence can be obtained by using the improved hybrid genetic algorithm in solution for optimization problem. Numerical simulation based on some typical examples demonstrate the effectiveness of the proposed method.

Application of multimedia technology in teaching and knowledge transfer is booming. Pilot experiment uses interactive computer-based gaming in which people play a role in the system being modeled. The behavior of subjects can then be directly compared against the behavior produced by the assumed decision rules of the model. Interactive Learning Environment (ILE) methodology provides a mimic real system for testing economic theories and generating hypotheses. The ILE developed in the paper serves as a tool for understanding the simple structure of a social-ecological system and testing the subject’s misperception of delays. Through their investment decisions, subjects attempt to balance the water in lake to the desired level over time. But without taking consider into the delays existed in the system, it's hard for them to successfully complete the task. The results demonstrate people's misperception of delays in their decision making process.
多媒体技术在教学和知识传递中的应用正在蓬勃发展。试点实验使用交互式电脑游戏,人们在被建模的系统中扮演一个角色。然后,可以直接将受试者的行为与模型假设的决策规则产生的行为进行比较。交互式学习环境(ILE)方法为检验经济理论和产生假设提供了一个模拟真实系统。本文开发的ILE可作为理解社会生态系统的简单结构和测试被试对延迟的误解的工具。通过他们的投资决策,受试者试图随着时间的推移将湖中的水平衡到理想的水平。但是如果不考虑系统中存在的延迟,他们很难成功完成任务。结果表明,人们在决策过程中对延迟存在误解。

Apply Rough Set Theory into the Information Extraction The Application of the Clustering 粗糙集理论在信息提取中的应用
Pub Date : 2009-11-13 DOI: 10.1109/NCM.2009.297
Wen-Yau Liang
Clustering has always been an important subject in data mining, and it has been applied in various domains. Constrained clustering has been an emerging issue over the last few years. Its main idea is applying constraints to the process of clustering to decrease the running time and cost to expectantly promote the quality of clustering. Because clustering is a combinative optimization question, there are some problems such as NP-Hard work and deciding the number of clusters. This paper proposes a constrained clustering technique combining Rough Set theory and Genetic Algorithm into the clustering. We also developed the prototyping system and performed experiments to prove the effectiveness and compare it with other clustering techniques, such as Genetic Algorithm-based clustering and Self-organizing Maps. Finally, the results showed our approach is actually better than other methods.
聚类一直是数据挖掘中的一个重要课题,在各个领域都有广泛的应用。约束集群在过去几年中一直是一个新兴的问题。其主要思想是在聚类过程中施加约束,以减少运行时间和成本,从而预期地提高聚类的质量。由于聚类是一个组合优化问题,因此存在NP-Hard工作和聚类数量的确定等问题。本文提出了一种结合粗糙集理论和遗传算法的约束聚类技术。我们还开发了原型系统并进行了实验来证明其有效性,并将其与其他聚类技术(如基于遗传算法的聚类和自组织地图)进行了比较。最后,结果表明我们的方法实际上优于其他方法。

Jung-San Lee, Bo Li, Yung-Chen Chou
For the explosive development of mobile technologies, mobile stations have become an important role in our daily life. People can use cellular phone not only for communications including message, voice, and video, but also for trade. In this article, we aim to propose a brand-new value-added service for mobile subscribers, M-check. A subscriber can apply the new service to trade with a virtual vendor or perform some business transactions. In addition to preserving the property from physical checks, M-check provides more convenience and flexibility. A subscriber needs not to sustain the risk of physical check loss or damage, and is able to trade with others over the Internet or physical merchant.

Kernel-Perfection through the Push Operation 通过Push操作实现内核的完美
Pub Date : 2009-11-13 DOI: 10.1109/NCM.2009.386
Scott Heard, Jing Huang
Let $D = (V,A)$ be a digraph.A kernel of $D$ is an independent set $S$ of vertices such that every vertexof $D$ is either in $S$ or dominates a vertex in $S$. If every inducedsubdigraph of $D$ has a kernel, then $D$ is called kernel-perfect.According to Richardson, if a digraph does not contain a directed cycle of oddlength then it is kernel-perfect. Here we study the kernel-perfection throughuse of the push operation of digraphs. For a subset $X$ of vertices of $D$,$D^X$ is the digraph obtained from $D$ by pushing $X$, that is, reversingthe directions of arcs between $X$ and $V-X$. We prove that the problem ofdeciding if a digraph can be pushed to be kernel-perfect is an NP-completeproblem. This is on contrast to a previous result showingthe same decision problem restricted to chordal digraphs is polynomial timesolvable. We further show that the problem of deciding whether a graphcan be pushed to contain no directed cycle of odd length is also NP-complete.
设$D = (V,A)$是一个有向图。D$的核是一个独立的顶点集$S$,使得$D$的每个顶点要么在$S$中,要么支配$S$中的一个顶点。如果$D$的每个诱导子图都有一个核,则$D$称为核完美的。根据Richardson,如果一个有向图不包含奇数长的有向环,那么它就是核完美的。这里我们通过有向图的推操作来研究核完备性。对于$D$的顶点子集$X$, $D^X$是通过推动$X$从$D$得到的有向图,即颠倒$X$和$V-X$之间的弧线方向。我们证明了判定一个有向图是否可以被推为核完美的问题是一个np完全问题。这与先前的结果形成对比,该结果表明,限制于弦向图的相同决策问题是多项式时间可解的。我们进一步证明了判定一个图是否可以被推到不包含奇数长度的有向环的问题也是np完全的。
