  • A Database-Independent Approach of Mining Association Rules with Genetic Algorithm 
    Yan Xiaowei; Zhang Chengqi; Zhang Shichao (Springer-Verlag, 2003)
    Apriori-like algorithms for association rules mining rely upon the minimum support and the minimum confidence. Users often feel hard to give these thresholds. On the other hand, genetic algorithm is effective for global ...
  • A Database-Independent Strategy for Confidence Determination 
    Zhang Chengqi; Yan Xiaowei; Zhang Shichao (Knowledge Systems Institute, 2003)
    Traditional association rules mining algorithm depends on two user-specified thresholds. One is the minimum support, which is statistically required. Another is the minimum confidence. Users or even experts are difficult ...
  • Data mining in collaborative virtual environments: an integrating framework. 
    Simoff Simeon; Biuk-Aghai Robert (N/A, 2001)
    Collaborative virtual environments are becoming an intrinsic part of professional practices. In addition to providing communication and collaboration means, they have the potential to collect tremendous amounts of data ...
  • Dealing with inconsistent secure messages 
    Chen Qingfeng; Zhang Shichao (Springer-Verlag, 2004)
    In this paper we propose a formal framework for dealing with the inconsistency in secure messages with weights, WhIChtakes into account both the freshness and dynamic properties of secure messages. This enables us to ...
  • Debating the OO debate: where is the problem? 
    Berglund Anders; Lister Raymond (Australian Computer Society, 2008)
    Abstract: In this paper we discuss problems related to the teaching of object-oriented programming (OOP). We argue that more research on how the computer science teacher understands OOP would be beneficial. ...
  • Debt Detection in Social Security by Sequence Classification Using Both Positive and Negative Patterns 
    Zhao Yanchang; Zhang Huaifeng; Wu Shan Shan; Pei Jian; Cao Longbing; Zhang Chengqi; Bohlscheid Hans-Michael (Springer, 2009)
    Debt detection is important for improving payment accuracy in social security. Since debt detection from customer transactional data can be generally modelled as a fraud detection problem, a straightforward solution is to ...
  • Decidable fragments of first-order language under stable model semantics and circumscription 
    Zhang Huqiang; Ying Mingsheng (The AAAI Press, 2010)
    The stable model semantics was recently generalized by Ferraris, Lee and Lifschitz to the full first-order language with a syntax translation approach that is very similar to McCarthy's circumscription. In this paper, we ...
  • Decision making in multi agent coalitionsin a dynamic hostile world 
    Goyal Madhu (Massey University, 2006)
  • Decision-making in Software Development 
    Mcbride Thomas (IEEE Press, 2008)
    There are many decisions made during the processes of software development and there are several decision-making methods that could be used in any specific circumstance. International standards for software and systems ...
  • A decision making model for vendor-buyer inventory systems 
    Wee Hui-Ming; Lu Jie; Zhang Guangquan; Chiao Huai-En; Gao Ya (Springer, 2009)
    In a vendor-buyer supply chain, the buyer's economic order quantity and the vendor's optimal number of deliveries are derived either independently or collaboratively. In this paper, we establish a two-stage vendor-buyer ...
  • A Decision Support System for Fuzzy Bilevel Decision Making 
    Gao Ya; Zhang Guangquan; Lu Jie; Goyal Madhu (World Scientific Publishing Co., Inc., 2008)
    Bilevel decision techniques are developed for decentralized decision problems, which may be defined by fuzzy coefficients. Based on a fuzzy linear bilevel (FLBL) model and two FLBL algorithms, this research develops a FLBL ...
  • A Decision Support System for Ore Blending Cost Optimization Problem of Blast Furnaces 
    Zhang Ruijun; Wei Jizhong; Lu Jie; Zhang Guangquan (Springer-Verlag, 2010)
    In iron and steel enterprises, it is difficult to obtain the lowest-cost optimal solution to an ore blending problem for blast furnaces by using the traditional trial-fault-trial (TFT) method because of the complexity of ...
  • Defining an Integrated Agile Governance for Large Agile Software Development Environments 
    Qumer Asif (Springer-Verlag Berlin Heidelberg, 2007)
    This paper highlights the important aspect of IT governance, with the objective of defining an unaddressed aspect of agile governance, by the application of an iterative, inductive, instantaneous analysis and emergent ...
  • Defining the criteria for supporting pervasiveness in complex adaptive systems 
    Mir Shiva (ICST Gent, 2010)
    This paper, will explore potential contributions from the study of complexity theory to the area of pervasiveness of information systems. It offers insights for enriching traditional approaches of information system design ...
  • Delegating Responsibility in a Multiagent Process Management System 
    Debenham John (Association for Computing Machinery, 2003)
    In a multiagent process management system the distribution of work is achieved by negotiated delegation of responsibility for sub-processes by one agent to another. The responsibility delegation mechanism is based on a ...
  • Delegating responsibility in an autonomous multiagent system 
    Debenham John (IOS Press, 2004)
    In a multi agent system agents negotiate with one another to distribute the work in an attempt to balance the incompatible goals of optimising the quality of the result, optimising system performance, maximising payoff, ...
  • Delta-Equalities of Complex Fuzzy Relations 
    Zhang Guangquan; Dillon Tharam; Cai Kai-Yuan; Ma Jun; Lu Jie (IEEE Computer Society Conference Publishing Services (CPS), 2010)
    A complex fuzzy relation is defined as a fuzzy relation whose membership function takes values in the unit circle on a complex plane. This paper first investigates various operation properties of a complex fuzzy relation. ...
  • Denial-of-Service Attack Detection Based on Multivariate Correlation Analysis 
    Tan Zhiyuan; Jamdagni Aruna; He Xiangjian; Nanda Priyadarsi; Liu Ren Ping (Springer-Verlag, 2011)
    The reliability and availability of network services are being threatened by the growing number of Denial-of-Service (DoS) attacks. Effective mechanisms for DoS attack detection are demanded. Therefore, we propose a ...
  • Dependence Testing and Vectorization of Multimedia Agents 
    Xu Richard; Allen John; Jin Jesse S (CSREA Press, 2005)
    We present a dependence testing algorithm that considers the short width of modern SIMD registers in a typical microprocessor. The test works by solving the dependence system with the generalized GCD algorithm and then ...
