对于机器翻译研究来说，本章的第一任务是要建立语言的机器词典, 这一机器词典是多语言的。例如各自的藏, 英, 汉语机器词库。 单词与词组的处理与分析, 对于汉语来说, 首先必须要进行单词的自动切分。自动切分歧义部分是解决的难点, 不但可能用到规则推理, 而且还可能用到语法分析, 语义用分析, 更详细的过程可以结合第六章等一起研究。 词语分类和兼类的分析与处理是本章研究的又一重点。 本章的最后将研究词处理的一些细节问题。 5 . 1 机器词典概述 5 . 2 自动分词 5 . 3 词语的排序, 检索, 词库 5 . 4 词语的分类与兼类问题 5 . 5 词语处理的其它问题 5 . 6 . 1 概述 5 . 6 . 2 多义词类型 5 . 6 . 3 消歧方法 5 . 5 . 7 英语形态还原

this problem you will study how to represent various concepts and quantify various relations with membership functions when there is more than one universe of discourse. Use minimum to quantify the\and.\For each part below, there is more than one correct answer. Provide one of these and justify your choice in each case. Also, in each case draw the three-dimensional

There are many concepts that are used in fuzzy sets that sometimes become useful when studying fuzzy control. The following problems introduce some of the more popular fuzzy set concepts that not treate were not treated earlier in the chapter. (a)The\support\ of a fuzzy set with membership function (x) is the(crisp) set of all points x on the universe of discourse such

Develop a graphical depiction of the operation of the fuzzy controller for the inverted pendulum similar to 3 π the one given in Figure2.1 99 on page46. For this choose(t)=andet)=, which will result in four rules being on. Be sure to show all parts of the graphical depiction

There are many concepts that are used in fuzzy logic that sometimes become useful when studying fuzzy control. The following problems introduce some of the more popular fuzzy logic oncepts that were not treated earlier in the chapter or were treated only briefly (a)The complement(\not )of a fuzzy set with a membership function has a membership function given by A(x)=1-u(x). Sketch the complement of the fuzzy set shown in Figure 2.6 on page 30 (b)There are other ways to def ine the\triangular norm\for representing

In this problem we will study the effects of adding rules to the rule- base. Suppose that we use seven triangular membership functions on each universe of discourse and make them uniformly distributed in the same manner as how we did in Exercise 2.3. In particular make the points at which the outermost input membership functions for e saturate at +r/2 and for e at tr/4 For u make the outermost ones have their peaks

problem you will study how to represent various concepts and quantify various relations with membership functions. For each part below, there is more than one correct answer. Provide one of these and justify your choice in each case. (a)Draw a membership function (and hence define a fuzzy set) that quantifies the set of all people of medium height

基于人工神经网络( Artificial Neural Network)的控制(ann-based Control)简称神经控制(Neural Control)。神经网络是由大量人工神经元(处理单元)按照一定的拓扑结构相互连接而成的一种具有并行计 算能力的网络系统。它是在现代神经生物学和认识科学对人类信息处理研究的基础上提出来的,具有很强 的自适应和学习能力、非线性映射能力、鲁棒性和容错能力

Questions: Why do we select fuzzy controllers in many real-world- systems? How much of the success can be attributed to the use of the mathematical model and conventional control design approach? How much should be attributed to the clever heuristic tuning that the control engineer uses upon implementation?
