Therefore , it is the same with data mining with probability statistic character and knowledge discovery problems , especially with die problems that obtain sample information or need high cost 因此，适用于具有概率统计特征的数据采掘和知识发现问题，尤其是样本难以获取或代价过于昂贵的问题。
In the third chapter , the origin of uncertainty and random field model as well as the probability characteristics of soil parameters , including self - correlation and cross - correlation , are introduced 第三章分析土性参数的概率统计特性,包括参数不确定性的来源、随机场理论模型、土性参数的自相关性和互相关性等。
The work includes several parts as the following : firstly , fatigue and fracture reliability theory is introduced , along with the statistics theory and its application in fatigue reliability analysis 论文包括以下几个部分的内容：论文首先阐述了疲劳断裂可靠性一般理论以及应用于疲劳可靠性分析中的概率统计基础理论。
The sixth part tries to find a way to improve the efficiency of dock loading and unloading system . the seventh part gives a method about how to possess optimum machinery number by employing probability tool 第七章利用概率统计方法，确定各类型机械的合理拥有量，给港口设备部门的机型选购、机械出让决策，提供辅助参考。
Some researchers have put forward or implemented various approaches , including those based on statistics , on pattern predicting and on neural networks . some of these approaches are still under research 研究人员先后提出或采用了基于概率统计、基于模式预测、基于神经网络等多种方法，其中有一些目前仍处于理论研究阶段。
Research on wind is the precondition of wind response , then the section plane of static wind , intensity of onflow , psd function and correlativity of dynamic wind are involved in 对风的研究是进行风振响应研究的前提,风的基本特征包括平均风速剖面、湍流强度、脉动风功率谱密度函数、脉动风的空间相关性以及极端风速的概率统计特性。
Spamassassin is a score - based filter , which means that after applying all of its rules to a message , it comes up with a score that hopefully represents the likelihood that a message is spam 尽管spamassassin确实使用匹配规则来标识可能是垃圾邮件的邮件，但它采用了一种概率统计的、基于分数的方法来对消息分类，而没有采用二进制方法。
Through computing probabilities of received packets on destination port and destination ip address and comparing with normal threshold , system finds out the intrusion activities and writes it into alert log file 本文采用异常检测的方法，通过对到达目的ip和目的端口的syn包的概率统计，计算其异常值并和门限值比较，有效检测出synflood攻击。
The assess to tunnel lining concrete thickness lack many statistic data , all the same adopt un - statistic means to assess , advise adopt the probability statistic expression after gain lots of practice data 隧道二次衬砌混凝土的厚度评定由于缺乏大量的统计数据，仍然采用非概率统计方法判定，建议在取得大量的统计数据后，应采用概率统计方法表达。
