遗传算法(Genetic Algorithm, GA)是近几年发展起来的一种崭新的全局优化算法，它借 用了生物遗传学的观点，通过自然选择、遗传、变异等作用机制，实现各个个体的适应性 的提高。这一点体现了自然界中"物竞天择、适者生存"进化过程。1962年Holland教授首次 提出了GA算法的思想，从而吸引了大批的研究者，迅速推广到优化、搜索、机器学习等方 面，并奠定了坚实的理论基础。 用遗传算法解决问题时，首先要对待解决问题的模型结构 和参数进行编码，一般用字符串表示，这个过程就将问题符号化、离散化了。也有在连续 空间定义的GA(Genetic Algorithm in Continuous Space, GACS)，暂不讨论。

Boosting is a meta-learning approach that aims at combining an ensemble of weak classifiers to form a strong classifier. Adaptive Boosting (Adaboost) implements this idea as a greedy search for a linear combination of classifiers by overweighting the examples that are misclassified by each classifier. icsiboost implements Adaboost over stumps (one-level decision trees) on discrete and Continuous attributes (words and real values). See http://en.wikipedia.org/wiki/AdaBoost and the papers by Y. Freund and R. Schapire for more details [1]. This approach is one of most efficient and simple to combine Continuous and nominal values. Our implementation is aimed at allowing training from millions of examples by hundreds of features in a reasonable time/memory.

From helping to assess the value of new medical treatments to evaluating the factors that affect our opinions and behaviors, analysts today are finding myriad uses for categorical data methods. In this book we introduce these methods and the theory behind them. Statistical methods for categorical responses were late in gaining the level of sophistication achieved early in the twentieth century by methods for Continuous responses. Despite influential work around 1900 by the British statistician Karl Pearson, relatively little development of models for categorical responses occurred until the 1960s. In this book we describe the early fundamental work that still has importance today but place primary emphasis on more recent modeling approaches. Before outlining

As information technology is more and more in-depth and wide range of applications, management information system has been gradually implemented in the technical maturity. Management Information System is a Continuous development of new disciplines. Library Management System is a typical management information system (MIS), the development includes the background of the establishment and maintenance of database and front-end application development aspects. Database requested data consistency, integrity and the security of the data, and front-end applications require complete functions, such as easy-to-use. After analysis, I chose companies MICROSOFT VISUAL BASIC and Access prospects were as database development tools and background. With the provision of the various object-oriented development tools, in particular the data window convenient and simple objects developed intelligent customer satisfaction systems.

In this paper, we present LOADED, an algorithm for outlier detection in evolving data sets containing both Continuous and categorical attributes. LOADED is a tunable algorithm, wherein one can trade off computation for accuracy so that domain-specific response times are achieved. Experimental results show that LOADED provides very good detection and false positive rates, which are several times better than those of existing distance-based schemes.
