骑士精神的英文作文
骑士精神的英文作文英文:As a knight, the spirit of chivalry is deeply ingrained in my being. It is not just a code of conduct, but a way of life. The knight's code of honor dictates that one shouldbe brave, loyal, courteous, and true to one's word. These values have been passed down through generations of knights, and they continue to inspire me to this day.One of the most important aspects of the knight's codeis bravery. A knight must be willing to face danger and adversity with courage and determination. This means standing up for what is right, even when it is difficult or unpopular. I remember a time when I stood up to a group of bullies who were harassing a young boy. It was not an easy thing to do, but I knew it was the right thing. My bravery inspired others to stand up as well, and soon the bullies were no longer a problem.Another key value of chivalry is loyalty. A knight must be true to his word and loyal to his friends and allies. This means standing by them in times of trouble and supporting them in their endeavors. I once had a friend who was going through a difficult time. I stood by him and helped him through his struggles. My loyalty to him strengthened our bond, and he has remained a close friend ever since.Courtesy is also an important part of the knight's code.A knight must be polite and respectful to all people, regardless of their social status or background. This means treating others with kindness and consideration, and always striving to be a gentleman. I remember a time when I heldthe door open for an elderly woman who was struggling to carry her groceries. She thanked me and told me that I reminded her of her late husband, who was also a gentleman. It was a small act of courtesy, but it made a bigdifference in her day.Finally, a knight must be true to his word. This means keeping promises and fulfilling obligations, even when itis difficult or inconvenient. I once made a promise to a friend that I would help him move to a new apartment. When the day came, I was feeling sick and tired, but I knew I had to keep my promise. I showed up and helped him move, and he was grateful for my help.In conclusion, the spirit of chivalry is a way of life for me as a knight. It inspires me to be brave, loyal, courteous, and true to my word. These values have helped me to become a better person, and I hope to pass them on to future generations of knights.中文:作为一名骑士,骑士精神已经深深地扎根于我的内心。

D ISCOV ER target FROMdom ain W H ER Efocus 2constraints I N T ER EST Sinteresting po ints PA RAM ET ERsuppo rt ,confidence COND IT I ONdiscre —cond contin —cond DOM A I N dom ain 2know ledgeI N T ER EST S 子句指出用户感兴趣属性,其作用是约束发现目标,细化发现任务.PA RAM ET ER 子句指定知识发现过程涉及的支持度和置信度阈值.COND IT I ON 子句给出预处理所需的两种规格化条件.DOM A I N 子句给出用户感兴趣属性的语义层次关系,其作用是对该属性进行归约,提高发现知识的抽象度.FROM 子句和W H ER E 子句的语法和语义与SQL 语言中的相同.发现语言首先被分析转换成标准SQL 语言和控制信息,图2给出发现语言的处理过程示意图.与传统的知识发现语言相比,Knigh t 系统的发现语言增加了COND IT I ON 子句和DOM A I N 子句.一方向,对数据对象的规格化和归约有助于减少计算,提高效率,另一方面,可以很好地适应用户不同层次的知识发现任务的需要,增加了系统的灵活性.图2 发现语言处理过程示意图4 Kn ight 系统的设计思想及特点411 知识的表示知识的表示形式有多种.自然语言描述直观,易于理解,为早期的一些专用系统所采用,如Exp lo ra .但自然语言描述限制较多,知识形式过于单一,往往无法满足多种发现任务的需要.形式逻辑描述有利于推导,表示简单、灵活,一些通用系统如I NL EN 大都采用这种形式.形式逻辑描述的缺陷也是明显的,结果知识不够直观,对用户要求较高.除此之外,知识的表示还有神经网络、框架表示、产生式系统等多种,它们各有优劣.043计算机研究与发展1998年Knigh t 系统在知识表示形式上充分考虑了系统的特点.Knigh t 系统的目标是一个通用的知识挖掘工具,为了支持多种知识的发现,需要多种不同的知识发现算法,适应不同发现算法的知识表示形式也不尽相同,因此,为提高发现算法的效率,Knigh t 系统采用了灵活的知识表示形式,即允许不同的知识发现算法采用不同的知识表示形式.Knigh t 系统的知识表示形式有四种,分别是:(1)逻辑规则:逻辑规则是形式逻辑描述的一种,用它来表示数据间的蕴含关系非常自然.在Knigh t 系统中,关联规则发现子模块和基于查询的知识发现子模块发现的知识采用逻辑规则表示;(2)宏元组:特征知识和分类知识是普化知识的两个方面,它的实质是对给定数据对象集的抽象和概括.系统采用了面向属性归约方法,一次归约就是一次元组的合并.Knigh t 系统用最终获得的宏元组来表示普化知识,非常简捷.(3)向量距离:Knigh t 系统的聚类分析模块采用了全新的聚类分析方法.它选用向量空间模型作为问题的描述,用遗传算子来替代传统算法中复杂的数学运算.根据算法的特点,系统用聚类中心向量和分类半径(向量距离)表示所得的分类模型.(4)数据方程:函数依赖发现子模块旨在发现属性间的函数关系,Knigh t 系统用以属性名为变量的数学方程表示.412 知识的预处理知识挖掘系统的处理对象是大规模数据库,数据量大,知识分散,发现算法复杂度高.一般来说,需要用户在控制机制中提供一定的交互式指导:①选择要展开工作的数据范围;②鉴别相关的域;③细化目标.Knigh t 系统的知识预处理模块完成相应功能.除了基本的剪枝和过滤,Knigh t 系统还提供了两个全新的预处理过程:规格化和归约.规格化指将元组集按规格化条件进行合并.规格化条件定义了属性的多个取值到给定虚拟值的对应关系.Knigh t 系统支持两种形式的规格化条件,分别适用于取值连续的数值属性和取值分散的属性.归约指将元组按语义层次结构合并.语义层次结构定义了元组属性值之间的IS 2A 语义关系.规格化和归约能大量减少元组个数,提高计算效率.同时,规格化和归约过程提高了知识发现的起点,使得一个发现算法能够发现多层次的知识,适应不同应用的需要.413 知识发现Knigh t 系统的知识发现模块提供了六种发现过程,按发现方法可分为五类:关联规则发现,普化知识发现,聚类分析,函数依赖发现,基于查询的知识发现.详尽的算法介绍[5]不现实也不必要,本文着重介绍Knigh t 系统在发现过程中引入的新的思想方法.(1)基于遗传算法的聚类分析方法聚类分析问题可以描述为:给定n 维空间R n 中的m 个向量,把每个向量归属到C 个聚类中的某一个,使得每个向量与其聚类中心的距离最小.聚类分析问题的实质是一个全局最优问题.K 均值算法是应用较广的算法,但它不一定能得到全局最优.其他一些寻优效果较好的方法大多需要大量的时间空间开销.鉴于遗传算法具有计算简单、优化效果好的特点,以及它在处理组合优化问题方面所具有的优势,Knigh t 系统就聚类分析问题引入遗传算法的思想.所有聚类中心组成问题的解,以向量距离的离差平方和作为评价函数,在系统设计的遗传算子交换和突变的交替作用下,不断获得新的解集,即新的聚类中心集合,从而使聚类分析逐步导向全局最优.Knigh t 系统采用扩展的遗传算法,解的表示(如图3)不选用二进制位串.一个聚类中心向量表示为一个基因(Gene ),所有聚类中心组成染色体(Ch romo som e ).1434期陈 栋等:Knigh t :一个通用知识挖掘工具Gene:cluster—centerCh romo som e:cluster—center cluster—center…cluster—center图3 解的表示 Knigh t系统设计了两种遗传算子:交换和突变.交换和突变操作引起聚类中心发生变化,在迭代过程中应对相应或距离接近的聚类中心进行归并,以减少聚类中心数目.①交换(cro ssover):交换操作示意如图4所示,图中,两个父辈染色体P1,P2,两个子染色体C1,C2.假设交换由第二个基因开始,一直到第i个基因结束.图4 交换操作示意图②突变(m utati on):突变操作示意如图5所示.图中P为突变前的染色体,C为突变后的染色体,箭头指示出了发生突变的基因CC i,及突变后的基因new.一般来说,new不属于原来的基因值域,而是CC i中各维变化的结果.迭代收敛结束后,我们得到聚类结果,每个类C j对应有一个聚类中心Z j再计算出每个类的最大半径R j,R j=m ax(‖X ij-Z j‖),i=1…m j,j=1…c. 于是,得到分类规则:如果‖X-Z j‖≤R j,则X∈C j.图5 突变操作示意图(2)信息论思想和谱化知识发现特征知识和分类知识是普化知识的两种主要形式,支持这两种知识发现的系统很多,其发现算法基本上可以分为两类:数据立方方法和面向属性归约方法.Knigh t系统采用了后者.普通的基于面向属性归约方法在归约属性的选择上有一定的盲目性.在归约过程中,当供选择的可归约属性有多个时,通常是随机选取一个进行归约.事实上,不同的属性归约次序获得的结果知识可能是不同的,根据信息论最大熵的概念,应该选用一个信息丢失最小的归约次序.最大熵[6]在科学、工程的许多应用已被成功地用作标准.Knigh t系统在其特征知识和分类知识的发现243计算机研究与发展1998年算法中引入了最大熵的方法,对于多个可选的属性,通过比较各个属性归约后所得数据子空间熵的大小来确定最优的归约次序.优化的属性归约次序保证了Knigh t 系统的特征知识和分类知识发现方法能获得高质量的结果知识.注意到归约属性的选择仅与相应数据子空间熵的相对大小有关,无需计算其准确值,Knigh t 系统采用比较和估算相接合的方法,大大减少了计算量.(3)基于查询的知识发现知识挖掘系统获取的知识常常与用户的兴趣相去甚远,这主要是由于在一个知识挖掘系统(特别是通用的知识挖掘系统)中,知识发现的实施依赖于用户对发现任务的描述,准确的任务描述要求对系统的知识发现种类有足够的了解、有一定的领域知识.对于普通用户,这样的要求往往得不到满足.基于查询的知识发现方法是一种全新的知识发现方法,它接受用户的数据库查询,分析查询的结果数据,获得以查询条件为前提,结果数据特征为结论的蕴含式知识.对于关系数据库中多表之上的查询,算法将查询涉及的单表中元组分为两类:对查询结果有贡献的元组称为正实例,其余的元组称为反实例.对正实例集和反实例集运用统计方法和面向属性的归约方法、数据立方方法等一系列普化知识的发现方法进一步分析,分别得到正反实例集的特征描述,于是,系统最终可以获得查询条件与正实例集特征描述间的蕴含关系以及查询条件与反实例集特征描述间的否定蕴含关系.5 结 论数据挖掘技术涉及领域广,难点多,发展时间短,理论不够完整,研究人员面临极大的挑战.Knigh t 系统在这方面作了有益的尝试,Knigh t 系统综合了前人的研究成果,同时引入新的思想方法.Knigh t 系统有两个特点:系统是一个通用的知识发现工具,适用于多个应用领域;系统在知识发现过程中引入新的思想方法,提高了知识发现的效率和获得知识的质量.参考文献1 H arinarayan V ,U ll m an J D ,R ajaram an A .I mp lem enting data cubes efficiently .In :P roc A CM S IG M OD Int’l Conf on M anagem ent of D ata .M ontreal ,1996.205_2162 H an J ,Fu Y Exp lo rati on of the pow er of attribute 2o riented inducti on in data m ining .In :Fayyad U M ,P iatetsky 2Shap iro G ,Sm yth P et a l eds .A dvances in Know ledge D iscovery and D ata M ining .Califo rnia :AAA I M IT P ress ,1996.399_4213 Ch iu D avid K Y ,A ndrew K C W .Cheung B .Info r m ati on discovery th rough h ierarch icalm axi m um entropy discretiza 2ti on and synthesis .In :P iatetsky 2Shap iro G ,F raw ley W J eds .Know ledge D iscovery in D atabase .Califo rnia :AAA I M IT P ress ,1991.125_1394 M atheus C J ,Chan P K ,P iatetsky 2Shap iro G .System fo r know ledge discovery in databases .IEEE T rans on Know l 2edge and D ata Engineering ,1993,5(6):903_9135 Chen M ing 2Syan ,H an J iaw ei ,Yu P S .D ata m ining :A n overview from a database perspective .IEEE T rans on Know ledge and D ata Engineering ,1996,8(6):867_8816 李德毅1发现状态空间理论1小型微型计算机系统,1994,15(11):1—63434期陈 栋等:Knigh t :一个通用知识挖掘工具。

The Canterbury Tales
The General Prologue
There was a knight, a most distinguished man, who from the day on which he first began To ride abroad had followed chivalry, Truth,honor,freedomand all courtesy. He had done nobly in his sovereign's war, And ridden into battle, none more far As well in Christendom as in heathen places, And ever honored for his noble graces.
Origins of Knighthood
• two elements: feudalism service as a mounted warrior • Time: Middle Ages(about 476-1453 ) • original place: south of France

the wrong kind of knight好句
the wrong kind of knight好句"The Wrong Kind of Knight" is a captivating tale that explores themes of courage, honor, and the complexities of knights and chivalry. The following are some of the noteworthy sentences from the story that exhibit its rich vocabulary, profound insights, and engaging narrative:"In a world where knights were expected to be strong and brave, Gareth felt like a squirming worm, weak and unworthy." This sentence beautifully captures Gareth's inner turmoil and self-doubt, setting the stage for his journey of self-discovery and growth."The knight's code was a heavy weight on his shoulders, a burden that seemed to grow heavier with each passing day." This metaphorical description of the knight's code as a weight on Gareth's shoulders effectively illustrates the pressure and responsibility that knights felt to uphold their honor and chivalry."In the dim light of the torch, the dragon's eyes glowed menacingly, and Gareth's heart sank. He knew he was no match for such a beast." This vivid description of the dragon and Gareth's fear heightens the tension and excitement, making the reader anxious to see how he will overcome this challenge."As he faced the dragon, Gareth realized that true courage wasn't about being fearless, but about facing your fears and doing what was right despite them." This profound insight into courage and bravery is a powerful message that resonates with readers, reminding us that courage is not the absence of fear, but the willingness to overcome it."The dragon's roar echoed through the cave, shaking the very foundation of Gareth's resolve. But he stood his ground, determined to prove that he was more than just a pretty face and a fancy uniform." This sentence showcases Gareth's determination and resolve, as he defies the dragon and challenges his own limitations, growing as a character in the process.These sentences not only exhibit the author's skillful use of language but alsoconvey profound themes and insights that make "The Wrong Kind of Knight" a memorable and thought-provoking read.。

骑士招聘作文英文怎么写
骑士招聘作文英文怎么写英文,As a knight, the recruitment process is pivotalin finding the right candidates to join our esteemed order. Allow me to outline the criteria and process for becoming a knight.First and foremost, bravery and valor are the cornerstones of knighthood. A knight must be willing to face danger and adversity head-on, without faltering. For example, in one of our recent battles against the dragon, Sir Robert displayed immense courage by charging fearlessly into the fray, inspiring his fellow knights to victory.Secondly, chivalry and honor are non-negotiable traits for any knight. Respect towards others, especially towards those weaker or in need, is paramount. I recall an instance where Dame Eleanor demonstrated exceptional chivalry by aiding a wounded traveler on her journey, even though it meant delaying her own quest.Furthermore, loyalty to the king and the realm is of utmost importance. A knight must be willing to defend the kingdom and its people with unwavering loyalty. Sir William exemplified this virtue when he refused to betray theking's trust, even under immense pressure from external forces.Additionally, skill in combat and mastery of weaponry are essential for any aspiring knight. Training in various forms of combat, such as swordsmanship and archery, is rigorous but necessary. Sir Henry spent countless hours honing his skills with the sword, eventually becoming one of the most formidable swordsmen in the kingdom.Lastly, a knight must possess a noble heart and a sense of justice. Acts of kindness and compassion towards all, regardless of their station in life, distinguish a true knight. Lady Isabella's tireless efforts to protect the innocent from injustice, even at great personal risk, serve as a shining example of this virtue.中文,作为一名骑士,招聘流程对于找到合适的候选人加入我们尊贵的骑士团至关重要。

Knight不确定理论投资行为分析
Knight不确定理论投资行为分析摘要:本文首先从风险与不确定性区别的角度引入不确定性的概念,然后分析不确定性对投资者行为影响。
继而分析不确定对投资者行为的影响。
接着给出决策理论的预备知识:相关记号与定义,期望效用理论的公理化假定等。
以此来分析在不确定条件下,以主观期望效用理论为基础发展的Choquet 期望效用理论行为决策模型。
关键词:不确定性;主观期望效用;Choquet期望效用一、引言在不确定性情况下,投资者在决策之前不能像在确定情况下一样知道真实的状态且能预见其结果,而事实上,投资者对未来可能出现的状态并不能预知哪个会发生。
因此,他不能理性的选择自己的行为。
1944年V on Neumann 等从一系列严格的理性偏好假定出发,运用逻辑和数学工具建立起风险投资者决策的期望效用函数。
此后,结合效用函数和投资者对风险的态度,更多的理论结果被研究者提出。
但是,其所用的概率都是外生的、客观的、预先知道的,而不是投资者的信念。
事实上,经济中客观概率很难知道,大部分情况下,自然状态下出现的概率并不是客观的,而是人为的,即是主观概率。
因此要描述实际情况就必须考虑投资者的行为,于是主观期望效用被提出。
并因为其模型简单灵活,成为分析投资者在不确定情况下决策行为的重要理论。
二、传统的不确定性行为决策模型2.1 风险与不确定性定义与区别对于风险与不确定性,许多经济学家对这两者的区别进行过研究。
在这个方面,Knight创造性地将不确定性与风险作了区分,而且还将其作为研究利润来源和企业家职能的重要线索。
为了说明风险与不确定性的差异,Knight把概率区分为三种来分析:先验概率(a priori probability)、统计概率(statistical probability)和估计(estimate)。
在第一、二种情况下,概率是可衡量的,但在第三种情况下,概率是不可衡量的。
他称前两种情况为“风险”,第三种情况为“不确定性”。
