查询词典 data mining

Business objectives and related different alternatives for each type of returners. Related data can be obtained through data mining and other methods.

业务目标和有关不同的选择对每种类型的停职工作的人有关数据可通过数据挖掘和其他方法。

The traditional algorithms of classification are no longer suitable because of the effect of the concept drift in data streaming. The research on fast and stable data mining systems with high accuracy has become more valuable in both theory and practice. The effect of low frequency concepts on time and space performance is studied and an LFCR algorithm is proposed in this paper, which reduces the low frequency concept with some mechanisms. The extensive experimental study shows that LFCR has improved performance in classification in comparison with RePro.

由于数据流中概念漂移现象的影响，使得传统的分类方法不再适用，因此研究快速、精确及稳定的数据流挖掘方法和系统具有较高的理论和应用价值；文章研究了基于频度的概念漂移中低频概念对分类时空性能的影响，提出了对其中的低频概念进行消减的算法，实验表明LFCR算法比RePro算法有更好的分类性能。

In this models, first we extract features and rules fromthe training data, then using these rules to detect new intrusion, by using this means, updating rules and system will be more faster and cheaper, and the detection rate is high, the result proves that using data mining technology for building Intrusion Detection System is viably and availably.

这个模型首先从训练数据中提取并得到规则，然后用这些规则去检测新的入侵，这样规则的更新和系统的更新很快也很低廉，而且检测率很高，实验证明将数据挖掘运用到入侵检测系统中是可行的，也是有效的。

In this paper a genetic algorithm four-dimension data assimilation system was applied to the more complex MM5 model, we verify the performance of the genetic algorithm assimilation system, we take the a heavy rainfall process during 04-05, July, 2003 as the experimental research object, and carry out data assimilation experiment of actual observation data, compare the experimental results of the genetic algorithm assimilation system and MM5 adjoint model assimilation system with the experimental results without assimilation, the following is the result:genetic algorithm assimilation system is used not only in a barotropic primitive equation but also in the complex model, MM5, for example, in the ideal experiment the result of the genetic algorithm assimilation system is better than the MM5 adjoint model assimilation system, in the assimilation experiment of actual observation data, whichever assimilation system is used, the initial field of numerical prediction model is effectively improved and the prediction effect of physical field and rainfall are somewhat enhanced.

本文将遗传算法的四维同化系统运用到更复杂的MM5模式中，在理想实验中验证遗传算法同化系统的性能，并以2003年7月4日"南京暴雨"作为研究对象，进行了实际观测资料的同化，并将遗传算法同化系统和MM5伴随模式同化系统得到的结果跟未同化的结果进行了比较，结果如下：遗传算法同化系统不仅可以用在正压原始方程模式上，同样也可以用在MM5等复杂模式上，理想实验证明了遗传算法同化系统优于MM5伴随同化系统，在实际观测资料同化中，采用两种方法的同化系统都能有效地改善数值预报模式的初始场，能在一定程度上提高物理量场和降水量的预报效果。

Thus requestsearnestly to dispose the very big molding machine database theplatform, this project, the large-scale machinery system takes on bythe UNIX system, because its system stability and the security are allgood, has the certain support and the safeguard to the serverstability, this number of times according to the project transplant,the language which uses is COBOL, COBOL took public face commerciallanguage, mainly for the data processing, the data collection and theanalysis using of, is suitable for the data processing domain, itslogical rigorousness, the grammar readability, the maintainability,with the COBOL language easy transplant, all is becomes the commercialapplication procedure first choice language the superiority and thecharacteristic, Through the above demand, an item like this startedabout the data transplant project.
