语言学 Concepts of Chapter 8

1 Chapter 8

Performative refers to sentences in the uttering of which one

performs an action. They can not be said to be true or false. For instance,

I name this ship the Queen Elizabeth.

In contrast, constative denotes sentences that describe or depict facts

or states of affairs and so may be either true or false. For example,

China has the biggest population in the world.

Austin suggests three basic senses in which in saying something is doing

something and three kinds of acts are performed simultaneously:

1）Locutionary act: The act of saying something: it’s an act of conveying

literal meaning by means of syntax, lexicon, and phonology, namely, the

utterance of a sentence with determinate sense and reference.

2）Illocutionary act: The act performed in saying something; its

illocutionary force is identical with the speaker’s intention. (In other

海底两万里第二部分第8章批注

英文回答：

Chapter 8 of the second part of "Twenty Thousand

Leagues Under the Sea" is an exciting chapter where the

Nautilus encounters a giant squid. Captain Nemo and his

crew engage in a fierce battle with the squid, showcasing

their bravery and skill. The vivid description of the fight

between the Nautilus and the squid creates a thrilling

atmosphere for the readers.

In this chapter, I particularly enjoyed the way Jules

Verne portrays the character of Captain Nemo. He is

depicted as a fearless and determined leader, guiding his

crew through the dangerous encounter with the squid.

Captain Nemo's calm and composed demeanor in the face of

danger is truly admirable. For example, when the squid

attacks the Nautilus, Captain Nemo remains focused and

orders his crew to defend the ship. His strategic thinking

数据挖掘CHAPTER8聚类分析

第八章聚类分析

设想要求对一个数据对象的集合进行分析，但与分类不同的是，它要划分的类是未知的。聚类(clustering)就是将数据对象分组成为多个类或簇(cluster)，在同一个簇中的对象之间具有较高的相似度，而不同簇中的对象差别较大。相异度是基于描述对象的属性值来计算的。距离是经常采用的度量方式。聚类分析源于许多研究领域，包括数据挖掘，统计学，生物学，以及机器学习。

在本章中，大家将了解基于大数据量上进行操作而对聚类方法提出的要求，将学习如何计算由各种属性和不同的类型来表示的对象之间的相异度。还将学习几种聚类技术，它们可以分为如下几类：划分方法（partitioning method），层次方法(hierarchical method)，基于密度的方法(density-based method)，基于网格的方法(grid-based method)，和基于模型的方法(model-based method)。本章最后讨论如何利用聚类方法进行孤立点分析(outlier detection)。

8．1 什么是聚类分析？

将物理或抽象对象的集合分组成为由类似的对象组成的多个类的过程被称为聚类。由聚类所生成的簇是一组数据对象的集合，这些对象与同一个簇中的对象彼此相似，与其他簇中的对象相异。在许多应用中，一个簇中的数据对象可以被作为一个整体来对待。

聚类分析是一种重要的人类行为。早在孩提时代，一个人就通过不断地改进下意识中的聚类模式来学会如何区分猫和狗，或者动物和植物。聚类分析已经广泛地用在许多应用中，包括模式识别，数据分析，图像处理，以及市场研究。通过聚类，一个人能识别密集的和稀疏的区域，因而发现全局的分布模式，以及数据属性之间的有趣的相互关系。

“聚类的典型应用是什么？”在商业上，聚类能帮助市场分析人员从客户基本库中发现不同的客户群，并且用购买模式来刻画不同的客户群的特征。在生物学上，聚类能用于推导植物和动物的分类，对基因进行分类，获得对种群中固有结构的认识。聚类在地球观测数据库中相似地区的确定，汽车保险持有者的分组，及根据房子的类型，价值，和地理位置对一个城市中房屋的分组上也可以发挥作用。聚类也能用于对Web上的文档进行分类，以发现信息。作为一个数据挖掘的功能，聚类分析能作为一个独立的工具来获得数据分布的情况，观察每个簇的特点，集中对特定的某些簇作进一步的分析。此外，聚类分析可以作为其他算法（如分类等）的预处理步骤，这些算法再在生成的簇上进行处理。

金钱力_Chapter8金钱不等于财富,金钱也有局限性

金钱，能买到血液，但买不到生命；能买到大床，但买不到睡眠；能买到书本，但买不到知识；可以买到性，但买不到爱；可以买房子，但买不到家；可以买到地位，但买不到尊敬；可以买到钟表，但买不到时间；可以买到一时的快乐，但买不到一辈子幸福。

1.金钱换不来健康和生命

即使有一千万美元，对于失去的东西已不具任何意义。因此，金钱并不是万能的。

理财大师到某大学传授理财之道，引来万人围听。在演讲会上，大师的举动和两个故事，给人们留下深刻印象：

被踩过的二十美元

演讲一开始，大师拿出一张干净的白色纸张，举到众人面前，问有没有人要，众人不知道大师要干什么，出于好奇，有些人举手说要。大师微笑着将白纸丢到地上，用脚踩了两下，顿时，白纸上几个黑色的脚印清晰可见。大师捡起来再问众人要不要时，几乎没有人再举手。

大师微笑着将白纸放到一边，拿出一张二十美元的钞票，高高举到众人面前，然后问道："谁要这二十美元？"片刻的骚动后，一群人的手举了起来，甚至后边的人挤着往前面，唯恐这二十美元落到他人手里。

大师看到这一幕微笑着，又说道："我打算把这二十美元送给你们其中的一位，但在我把钞票送出去之前，请允许我做一件事。"说完，他将钞票扔到地上，用脚使劲踩了几下，顿时崭新的纸币变得又脏、又皱。

"现在谁还要？"大师弯下腰，捡起纸币问道。还是有很多人举手说要。

大师又将纸币扔到地上，再用脚在上面碾了几下，然后捡起来，又一次问众人还有没有人要。很多人还是高举着手臂。

大师又将钞票揉成一团，使它看起来更像半截废报纸，而不是钞票。接着他再次问道："还想要吗？"这时，还是有人举手说要。

这时，大师又说话了："朋友们，同样是两张纸，为什么白纸只被我踩了一次就没人要了？而无论我怎么对待这张钞票，你们却依然说要呢？这就是金钱本身所具备的魔力。人为的破坏并没有导致钞票的贬值，它依旧值二十美元。任何人都可以拿着这张钞票购买几十张白纸，但你一定不能拿着白纸去购买任何东西。但转个念头，假如这个世界上没有白纸，当你需要时，即便你有一千万美元，对于失去的东西还有意义吗？所以，金钱并不是万能的。"
