【答案】: 参考答案:China didn"t have a high-speed rail five years ago.But now the tickets of high-speed trains are usually sold out very quickly, even though the departure interval is quite short.And people can conveniently travel around the nation at a speed that doubles the speed of the fastest American train.The operation of high-speed rail system is very successful; it carries twice as many passengers as the nation"s civil aviation system.China has one of the most advanced rapid transit systems with low emissions in the world, and it only takes five years to achieve this.

(3) 以 o 结尾的名词,有些加词尾 -s,有些加-es,但在中学英语范围内,以o结尾的名词变复数加词尾-es 的主要有以下4个:tomato(西红柿),potato(土豆),hero(英雄),Negro(黑人)。注:有些以o 结尾的名词在变复数时加-s或-es均可,如zero / zero(e)s(零)等。(4) 以 f 或 fe 结尾的名词,也有两种可能:即有些直接加词尾-s,有些则把 f / fe 改为 ves:roof / roofs(屋顶),knife / knives(小刀)等。但在中学英语范围内,要改 f / fe 为 ves 的只有以下10个词:wife(妻子),life(生命),knife(小刀),leaf(树叶),thief(贼),half(一半),self(自己),shelf(架子),loaf(面包),wolf(狼)。注:中学英语中的handkerchief(手帕)在变复数时有两种形式:handkerchiefs / handkerchieves,但在现代英语中,以用 handkerchiefs 为多见。3. 单数与复数同形的名词。这类名词不多,主要的有:sheep 绵羊 fish 鱼 deer 鹿Chinese 中国人 Japanese 日本人 Portuguese 葡萄牙人Swiss 瑞士人 aircraft 飞行器 means 方法series 系列 head (牛等的)头数 works 工厂注:(1) fish 有时也用 fishes 这样的复数形式,尤其是表示种类时;head 若不是表示牲口的“头数”,而是表示“人的头”或“人数”,则要用 heads 这样的复数形式。(2) 由汉语拼音形式出现的名词,其复数与单数同形,如 fifty yuan(5元),thirty fen(3角),five li(5里),ten mu(10亩)等。4. 名词复数的不规则变化。有的名词单数变复数时,没有一定的规则,需特别记忆:man / men 男人 woman / women 女人child / children 小孩 tooth / teeth 牙齿foot / feet 脚 goose / geese 鹅mouse / mice 老鼠 ox / oxen 公牛注:(1) 一些以 man, woman 结尾的合成词,在构成复数时与 man, woman 的变化形式相同,如:policeman / policemen(警察), Englishman / Englishmen (英国人),等等。但是 human(人),German(德国人),Walkman(随身听)不是合成词,它们的复数要按一般规则变化,即为 humans, Germans, Walkmans,而不是 humen, Germen, Walkmen。又如Bowman是姓,其复数是Bowmans,不是 Bowmen。(2) foot表示“英尺”时,其复数可以有两种形式 feet / foot,如:He is about six feet [foot] tall. 他大约6英尺高。5. 复合名词变复数的方法。复合名词变复数通常是将其主要名词变为复数:passer-by / passers-by 过路人 looker-on / lookers-on 旁观者若没有主要名词,则通常在最后一个词尾加s:know-all / know-alls 万事通对于由man / woman用于另一名词前构成的合成名词,则需将两者变为复数:man nurse / nurse doctors 男护士woman lawyer / women lawyers 女律师名词根据其可数性,可分为可数名词和不可数名词。一般说来,个体名词和大部分集合名词是可数的;而专有名词、物质名词、抽象名词以及小部分集合名词则通常是不可数的。但是这种区分只是大致的,原则性的,并不是绝对的。比如,在通常情况下专有名词具有“独一无二”性,因此它通常没有复数形式,即不可数。但是,专有名词的独一无二性有时是相对的,随着范围的扩大,这种独一无二性便会受到破坏。如在一个星期(week)内,只有一个星期六(Saturday), 一个星期日(Sunday)等,但是在一个月中甚至一年中,便有多个星期六,多个星期日了。又如,在一个小范围内,可能只有一个 Henry,但在一个较大的范围内则可能有多个 Henry, 因此我们有时会见到类似以下这样的句子:We have spent many happy Sundays there. There are five Henrys in our school. 另外,物质名词在通常情况下不能分为个体,所以它通常是不可数的。但是,在某些特殊情况下(如表示种类等),有些物质名词也可以连用不定冠词或用复数形式。如:Will you have tea or coffee Two coffees, please! 再如,抽象名词是表示事物性质、行为、状态、感情等抽象概念的,因此它通常是不可数的。但是,有时抽象名词也可转化为具体名词,表示具有某种性质的人、事物或行为(可数)。如:She did this out of kindness. 指抽象意义)He has done me many kindnesses. 指好意的行为)名词是表示人、事物、抽象概念等名称的词。根据其词汇意义,名词可分为专有名词和普通名词。 1. 专有名词:指表示人、地方、机构、组织等的专有名称。具体说来,它包括人名、地名、月份、星期、节日、书名、电影名以及某些抽象名词等。如:Jim 吉姆 China 中国 Mr. Smith 史密斯先生July 七月 Friday 星期五 the Yellow River 黄河Christmas 圣诞节 English 英语 A Tale of Two Cities 《双城记》注:专有名词的首字母通常要大写。若是专名名词词组,则其中每个单词的首字母要大写;若是缩略词,则通常每个字母都大写;称呼家人的 mum, dad, father, mother 等有时也可小写。2. 普通名词:指表示一类人或东西或抽象概念的名词。具体地说,它可分为个体名词、集合名词、物质名词和抽象名词。其中个体名词表示某类人或东西中的个体,如girl(女孩)等;集体名词表示若干个个体组成的集合体,如 audience(观众,听众)等;物质名词表示无法分为个体的实物,如water(水)等;抽象名词表示动作、状态、品质、感情等抽象概念,如work(工作),happiness(幸福)等。编辑本段名词的数的问题 1. 名词复数的规则变化 (1) 一般情况加词尾 -s,如 book / books, desk / desks等。(2) 以 s, x, z, sh, ch 等结尾的名词,通常加词尾 -es:bus / buses, box / boxes, dish / dishes等。(3) 以y 结尾的名词,其复数构成要分两种情况:以“辅音字母+y”结尾的名词,将 y 改为 ies;以“元音字母+y”结尾的名词,直接加词尾-s:city / cities, toy / toys, holiday / holidays 等。2. 复数规则变化的几点说明 (1) 以 ch 结尾的名词变复数时加词尾-es,指的是 ch 读音为[tF]时;若ch的读音为[k],则其复数应加词尾-s,如 stomach[tstQmEk]是 stomachs,而不是 stomaches。(2) 以y结尾的专有名词,直接加词尾s变复数。如:There are two Marys in our class. 我们班在两个玛丽。(3) 以 o 结尾的名词,有些加词尾 -s,有些加-es,但在中学英语范围内,以o结尾的名词变复数加词尾-es 的主要有以下4个:tomato(西红柿),potato(土豆),hero(英雄),Negro(黑人)。注:有些以o 结尾的名词在变复数时加-s或-es均可,如zero / zero(e)s(零)等。(4) 以 f 或 fe 结尾的名词,也有两种可能:即有些直接加词尾-s,有些则把 f / fe 改为 ves:roof / roofs(屋顶),knife / knives(小刀)等。但在中学英语范围内,要改 f / fe 为 ves 的只有以下10个词(它们都是日常生活中的常用词):wife(妻子),life(生命),knife(小刀),leaf(树叶),thief(贼),half(一半),self(自己),shelf(架子),loaf(面包),wolf(狼)。注:中学英语中的handkerchief(手帕)在变复数时有两种形式:handkerchiefs / handkerchieves,但在现代英语中,以用 handkerchiefs 为多见。3. 单数与复数同形的名词。这类名词不多,主要的有:sheep 绵羊 fish 鱼 deer 鹿Chinese 中国人 Japanese 日本人 Portuguese 葡萄牙人Swiss 瑞士人 aircraft 飞行器 means 方法series 系列 head (牛等的)头数 works 工厂注:(1) fish 有时也用 fishes 这样的复数形式,尤其是表示种类时;head 若不是表示牲口的“头数”,而是表示“人的头”或“人数”,则要用 heads 这样的复数形式。(2) 由汉语拼音形式出现的名词,其复数与单数同形,如 fifty yuan(5元),thirty fen(3角),five li(5里),ten mu(10亩)等。4. 名词复数的不规则变化。有的名词单数变复数时,没有一定的规则,需特别记忆:man / men 男人 woman / women 女人child / children 小孩 tooth / teeth 牙齿foot / feet 脚 goose / geese 鹅mouse / mice 老鼠 ox / oxen 公牛注:(1) 一些以 man, woman 结尾的合成词,在构成复数时与 man, woman 的变化形式相同,如:policeman / policemen(警察), Englishman / Englishmen (英国人),等等。但是 human(人),German(德国人),Walkman(随身听)不是合成词,它们的复数要按一般规则变化,即为 humans, Germans, Walkmans,而不是 humen, Germen, Walkmen。又如Bowman是姓,其复数是Bowmans,不是 Bowmen。(2) foot表示“英尺”时,其复数可以有两种形式 feet / foot,如:He is about six feet [foot] tall. 他大约6英尺高。5. 复合名词变复数的方法。复合名词变复数通常是将其主要名词变为复数:passer-by / passers-by 过路人 looker-on / lookers-on 旁观者若没有主要名词,则通常在最后一个词尾加s:know-all / know-alls 万事通对于由man / woman用于另一名词前构成的合成名词,则需将两者变为复数:man nurse / nurse doctors 男护士woman lawyer / women lawyers 女律师编辑本段名词的可数性问题 名词根据其可数性,可分为可数名词和不可数名词。一般说来,个体名词和大部分集合名词是可数的;而专有名词、物质名词、抽象名词以及小部分集合名词则通常是不可数的。但是这种区分只是大致的,原则性的,并不是绝对的。比如,在通常情况下专有名词具有“独一无二”性,因此它通常没有复数形式,即不可数。但是,专有名词的独一无二性有时是相对的,随着范围的扩大,这种独一无二性便会受到破坏。如在一个星期(week)内,只有一个星期六(Saturday), 一个星期日(Sunday)等,但是在一个月中甚至一年中,便有多个星期六,多个星期日了。又如,在一个小范围内,可能只有一个 Henry,但在一个较大的范围内则可能有多个 Henry, 因此我们有时会见到类似以下这样的句子:We have spent many happy Sundays there. 我们在那儿度过了许多个愉快的星期日。There are five Henrys in our school. 我们学校有五个亨利。另外,物质名词在通常情况下不能分为个体,所以它通常是不可数的。但是,在某些特殊情况下(如表示种类等),有些物质名词也可以连用不定冠词或用复数形式。如:Will you have tea or coffee 你喝茶还是喝咖啡?Two coffees, please! 请来两杯咖啡!再如,抽象名词是表示事物性质、行为、状态、感情等抽象概念的,因此它通常是不可数的。但是,有时抽象名词也可转化为具体名词,表示具有某种性质的人、事物或行为(可数)。如:She did this out of kindness. 她这样做是出于好心。(指抽象意义)He has done me many kindnesses. 他对我很关心。(指好意的行为)编辑本段名词的格的问题 1. 名词格的种类:英语名词有三个格,即主格、宾格和所有格。名词的主格和宾格形式相同,所以它们又统称作通格。当名词用作主语、宾语、表语时,用通格。英语名词的所有格表示所属关系,它分-"s 所有格和 of 所有格两种形式。2. –"s所有格的构成方法:单数名词或不带复数词尾-s的复数名词尾均加词加-s 构成所有格,但若复数名词已带有词尾-s,则只加省字撇(")构成所有格。如:We found the man"s wallet in a women"s room. 我们在女厕所找到了这个人的钱包。The test is beyond the students" abilities. 这测试超过了学生的能力。注:(1) 对于带词尾-s的单数名词,通常仍加-"s,而对于带词尾-s的人名,可加-"s 或只加省字撇("):I"m glad at the boss"s promise to increase the workers" pay. 我很高兴老板答应提高工人们的工资。(2) 如果两个名词并列,并且分别带有 -"s,则表示“分别有”;若只带一个 –"s,则表示“两者共有”。如:This is Tom and Jim"s room, and these are Jack"s and Mary"s rooms. 这间汤姆和吉姆的房间(两人共用),这两间是杰克和玛丽(各自)的房间。3. -"s所有格的用法特点:-"s 所有格主要用于有生命的东西,但有时也可用于无生命的东西,如用于表时间的名词后、用于表国家、城市的名词后、用于组织机构后、用于某些集合名词、用于度量衡及价值名词后等。如:What are today"s assignments 今天的作业是什么She"s had several months" experience. 她已有了几个月的经验。Hainan is China"s second largest island. 海南是中国第二大岛。Let"s wait in the station"s waiting-room. 我们车站候车室等吧。注:名词所有格并不一定表示所有关系,有时可能表示其他意义,如表示类别、动作执行者或承受者等。如:This is a children"s hospital. 这是一家儿童医院。(表类别)We were all waiting for the famous popular singer"s arrival. 我们都在等那位著名流行歌曲歌手的到来。(表动作执行者)They had no money to pay for their son"s education. 他们没有钱支付儿子的教育费用。(表动作承受者)关于名词作定语 名词在句子中可用作主语、表语、宾语补足语、定语、同位语、呼语等,其中最需引起注意的是名词作定语,因为它不仅容易用错,而且也是英语高考的一个重要考点。关于此问题同学们应注意以下几点。如:1. 通常用单数:即在通常情况,名词作定语要用单数形式。如:chemistry lesson 化学课 flower garden花园school gate 校门 room number房间号码welcome party欢迎会 letter box信箱book report读书报告 shoe store鞋店paper flower纸花注:“数词+名词”作定语时,其中的名词要用单数形式。如:a five-year plan 五年计划 an 18-year-old girl 18岁的女孩2. 用复数作定语的情形:在某些特殊情况下也可用复数名词作定语,这主要见于某些用作定语的名词只有复数形式没有单数形式,或虽有单数形式但用于特定含义时习惯上要用复数形式。如:goods train 货车 arms depot军火库customs papers 海关文件 clothes brush 衣刷an arts degree文科学位 savings bank储蓄银行另外,在某些特定表达中,用作定语的名词也通常用复数。如:careers guide 就业指导 (比较:career woman 职业女性)examinations board考试委员会 (比较:examination paper 试卷)the foreign languages department 外语系 (比较:language lab 语言实验室)

春运英文

关于春运英文如下:Spring Festival travel rush又被叫做年度全球最大规模的人口流动(the largest annual human migration in the world)。春运还有一种英文是 China"s annual Spring Festival travel rush,因为是中国特有,所以在前面加上“China"s annual”。在春节期间是中国的返乡客流高峰期(peak time for passenger transport),会有大批的人员返乡过年。在春节期间客流最大的就是火车(Train),还有现在更受欢迎的高铁动车(High-speed train)。高铁和动车虽然组成的英语单词都是一样的,但是整体的顺序是不一样的。高铁的英文缩写是CHSR(China High-speed Railway),而动车的英文缩写是CRH(China Railway High-speed)。虽然高铁和动车在很多比较专业的地方是有很大区别的,但是在普通人看来都是差不多的,并且在外国人看来也都是告诉列车,所以他们在英语中统称为“High-speed train”。在铁路列车里座位的选择也意味着价格的不同。火车上的座位一般分为:Standing ticket 站票、Hard seat 硬座、Hard sleeper 硬卧、Soft sleeper 软卧。高铁动车上的座位一般分为Second-class seat 二等座、First-class seat 一等座、Business-class seat 商务座。不过既然已经到春运了,就多学习一些出行的句子吧!Is there an airport bus to the city? 这里有从机场去市中心的巴士吗 ?Where is the bus stop (taxi stand)? 巴士车站在哪里 ?How much does it cost to the city centre by taxi? 乘计程车到市中心需要多少钱?

Railway transportation includes urban express railways, subways, light rails, and trolley cars.   Beijing, Shanghai, Chongqing, Wuhan, and Changchun are all planning to build such a network to conquer the traffic jams and serious pollution caused by the rapid increase of the urban population and the number of automobiles in China.   The network will have the advantages of cleanliness, security, punctuality, high speed, and large transport capacity, said the officials.   Financial and technological factors have hampered the development of such a system over the past three decades, and there are now only about 90 km of underground lines in the country with some 600 subway trains in use.   Now, however, Beijing alone is planning to build a railway system composed of 13 main routes and two extensions lines totaling 408 km, and increase the railway transport proportion to 50 percent from the present 15 percent, according to local officials.   China"s first urban railway line was in Beijing and began test operations in October 1969, and the second, in Tianjin, was open to traffic in December 1984.   描写高铁的高中英语作文篇3   It is a really hot topic now as many city had opened high-speed railway.

坐高铁比传统火车舒服英语

坐高铁比传统火车舒服英语是:Taking the high-speed rail is more comfortable than traditional trains。高速铁路,简称高铁,是指设计标准等级高、可供列车安全高速行驶的铁路系统。其概念并不局限于轨道,更不是指列车。 高铁在不同国家、不同时代以及不同的科研学术领域有不同规定。中国国家铁路局颁布的《高速铁路设计规范》文件中将高铁定义为:新建设计时速为250公里(含)至350公里(含)运行动车组列车的标准轨距的客运专线铁路。

高铁上的英语是什么口音

中式口音。美式口音与英式口音都有显著的特征,尤其是英式。美式吐词相对清晰但也有相当的连音,主要是句子中的单词发音完整,卷舌音俱全。英音则相对显著,容易区分,巨量连音,以及巨量省略音节,卷舌音几乎全部略去,因省略及连音过多,一般初学者很难听懂,需要适应。在国内,高铁上,地铁上都是中国人的中式口音。先说特点,现代汉语发音特点是偏重送气音与不送气音(比如t和d,发这两个音的时候其实整个口腔的布置以及声带的震动都是一样的,只是出气不出气罢了,题主可以试试,t整个胸腔送气,较重,而d只口腔送气,送气极少,较轻),而英文也则偏重浊音与清音。两个语言系统偏重的发音习惯不一样,自然先天的讲,发音就会有显著区别了(也就是所谓的听起来不像)。两种语言的表达习惯也决定了发音系统,中文送气音较多,表达时需要频繁换气,与之对应,中文的句子一般较短,故而通常一句一换。而英文因为句子一般极长,单词本身还长,一口气是说不完的,故其开发出了省气的习惯,开发了几个送气较少的音,如s音的弱出气版写作th,发音时以舌尖抵住上牙,阻挡气流输出,故而减少出气量。(关于语言发音差异的知识其实颇为复杂,这里尽量说的比较简单,如果题主感兴趣可以自行搜索)总之两门语言自身的差异就决定了作为非本土语言的使用者,发音上自然会有所差异。再说最重要的一点,中式发音不丢人!其实国际性的外语考试,如托福,在考察表达时,根本不在意口音,只看考生表达水准。我在学习日语和韩语时,我的老师告诉我,口音其实不影响一个人的正常表达,相反,它象征了使用者的来处,是使用者最骄傲的名帖,如今我大中国如此繁荣富强,国人应当以一口中式口音为傲,无需矫枉过正。(我本人的口音是英音,但只是因为接受了严格且长期的训练,并非本意,反而个人感觉比较遗憾)语言最基本的功能永远只是表达。表意清晰即可。希望以上回答对题主有所帮助。

关于武广高铁的英语基础写作

First built in 2005,the Wuhan-Guangzhou high-speed railway went into operation on December,26th,2009.Overall length of its main line are 1068 kilometers,and it goes through the following three provinces:Hubei,Hunan and Guangdong. The speed of the Wuhan-Guangzhou high-speed railway is 350km/h,the fastest speed in the world now,which makes it only three hours needed from Wuhan to Guangzhou,seven hours less than before.Besides,there are all kinds of faclities inthe train,which make your trip safe and comfortable so it is more humanoriented. However,the only fly in the ointment is that the train fare is too high and the station is quite far away from the downtown area.

马克思主义哲学的中心思想是什么?

马克思主义认为,全部社会生活在本质上是实践的,而实践的主体是具有一定思想认识的人。一方面,人的正确思想从实践中来,实践决定认识,是认识的源泉和动力、目的和归宿,同时也是检验认识正确与否的唯一标准。另一方面,认识对实践具有反作用,正确的认识推动正确的实践,错误的认识导致错误的实践。这就是实践与认识的辩证关系,也是马克思主义哲学的一个基本原理。

图神经网络是怎么炼成的:GNN基本原理简介

此文算是对Google Research这篇 A Gentle Introduction to Graph Neural Networks 神作的阅读笔记.十多年来,研究人员开发了一种称之为图神经网络(Graph Neural Networks,GNNs)的技术,旨在将如今在深度学习的诸多任务中摧枯拉朽的神经网络,应用到图结构之上,从而让神经网络捕捉到更错综复杂的交叉特征,以期待在一些任务上取得更佳的效果。鉴于操作图数据结构的复杂性,尽管已经发展了十几年,它在实际应用中却刚刚起步,即时是google也才开始研究将其被应用到药品研发、物理模拟、假新闻检测、交通预测和推荐系统等领域。 尽管GNN是一个新兴的研究领域,但图结构的数据其实在我们身边无处不在。那么什么是图呢? 这个理科生应该都清楚,图有点(Vertex)和边(Edge)两部分组成,一个图就代表了各个实体节点(node)之间的关系(edge): 每个节点或者边都可以包含它的一些属性信息,比如如果一个节点表示一个人,那么就可以包含这个人的姓名、性别、身高、体重之类的..我们研究需要的信息。 而这些信息,都可以用通用的向量的形式存入其中: 还有别忘了一点,边是可以有方向的,按此我们还能分为有向图或是无向图。边的方向代表了信息的传递方向,例如a是b的微信好友,那b也是a的微信好友,好友关系自然是没方向的,而比如a是b的爹,那显然b就不是a的爹,此时叫爹的关系就是有有方向的。 图结构的构建是非常灵活的,可以根据个人的设计构建出各种不一样的图。而作为开发者显然要结合实际解决的问题来构建合适的图。 正如前面所提到的,图无处不在。你可能已经熟悉例如知识图谱、社交网络之类的图数据。当时显然,图是一种极其强大的通用数据表示,传统神经网络中用到的欧式空间的数据,同样可以用图来表示,例如可以将图像和文本建模为图结构数据。 比如,我们可以将一张图片的每个像素作为图的节点,再将相邻的像素用边连接起来,就构造了一个该图像的图。 如上图展示了一个5*5的图片的邻接矩阵表示和图表示。 我们将每个单词作为节点,并将每个节点连接到下一个节点,就得到了一个文本的图: 当然,在实践中我们并不会这样来编码文本和图像,因为所有的图和文本都是非常规则的结构,表示成图就多此一举了。 我们再来看一些例子,这些数据的结构更加复杂,除了图之外很难用其他方式来表达。 分子是构成物质的基石,我们可以用节点来表示它的原子和电子,用边来表示共价键,这样便将一个分子表示成了一个图: 不同的图可以表示出不同的分子结构: 都说社会是一个大熔炉,身处其中的人和事物之间会发生极其复杂的关系。这种关系的表示用普通的表格数据是很难表示的,而图却能很好的展现。 下图是将莎士比亚歌剧《奥赛罗》中的任务关系表示成图: 怎么样,如果没看过歌剧能推测出那些是主角吗? 下面是将一个空手道竞标赛的对战关系构建为图: 类似的可以表示为图的数据还有很多很多,比如论文的引用之类统统都可以表示为图,下面是现实世界中不同规模的数据图表示的统计数据: 可见,各种各样规模的数据都可以轻松的用图来表示。 在上面我们列举了这么多的图,那么我们该对这些图数据执行什么任务呢? 图上的预测任务一般分为三类: 下面我们通过具体的示例来说明GNN怎么来解决上述的三个级别的预测问题。 在图级别的任务中,我们的目标是预测整个图的属性。例如我们通过分子图,来预测该分子的气味或是者它是否是与某些疾病有关的受体。 它的输入是完整的图: 输出是图的分类: 节点级任务一般就是预测每个节点的类型。 一个经典的例子就是Zach的空手道俱乐部。该数据集市一个单一的社交网络图,犹豫政治分歧,讲师Hi先生和管理员John之间不和导致空手道俱乐部分裂,其中的学员一部分效忠于Hi先生,一部分效忠于John。每个节点代表空手道联系着,边代表空手道之外这些成员的互动,预测问题就是判断这些节点是效忠于谁的。 边级任务其实就是预测每个边的属性. 在目标检测的语义分割任务中,我们也许不止要识别每个目标的类型,还需要预测各个目标之间的关系.我们可以将其描述为边级别的分类任务:给定表示图像中的对象的节点,我们希望预测哪些节点共享一条边,或者该边的值是多少。如果我们希望发现实体之间的连接,我们可以考虑图是完全连通的,并根据它们的预测值修剪边来得到一个稀疏图。 用图表示就是这样的过程: 那么我们要如何使用神经网络来处理上述各种类型的任务呢? 首先要考虑的是如何将图结构数据适配到神经网络. 回想一下啊,传统的神经网络输入的往往是矩阵形式的数据,那么要如何把图作为输入呢? 图表示有四种类型的信息:节点(nodes),边(edges),全局上下文(global-context),联通性(connectivity).对于前三种信息,有一个非常简单的方案,比如将节点排序,然后每个节点表示为一个向量,所有节点就得到了一个节点的矩阵,同理,边和上下文也可以这么搞. 但是要标识连通性就没有这么简单了,也许你会想到用临街矩阵来表示,但是这样表示会有明显的缺陷,因为节点数的规模往往是巨大的,对于一个数百万节点的图,那将耗费大量的空间,而且得到的矩阵往往也十分的稀疏,可以说空间利用率会很低. 当然,你也许会想,可以用稀疏矩阵来存储,这样就只需要存储连通的情况,空间利用率将大大提升,但是我们还要考虑到一点,就是稀疏矩阵的高性能计算一直是个艰难的,尤其是在用到GPU的情况. 并且,使用邻接矩阵还有一个问题就是各种不同的邻接矩阵可以标识相同的连通性,而这些矩阵并不能保证在神经网络中取的相同的效果.比如,同样的连通性,通过调换列的顺序,就能得到不同的邻接矩阵:现在,我们成功的将图结构成功表示成了置换不变的矩阵格式,终于可以使用图形神经网络(GNN)来做图形预测任务了。 GNN是对保持图对称性(置换不变性)的图的所有属性(节点、边、全局上下文)的可优化变换。 我们将使用Gilmer等人提出的“消息传递神经网络”框架构建GNN,并使用Battaglia等人介绍的图网络网络架构示意图。GNNS采用“图输入,图输出”架构,这意味着这些模型类型接受图作为输入,其中包含节点,边和全局上下文的信息,并逐步地转换这些图嵌入,而不会更改输入的连接图结构。 我们使用最开始提到的那个图来构建一个最简单的GNN,输入的图是相应节点,边,全局信息的向量,我们针对每个向量使用一个MLP层来作变换,于是得到一个新的图. 针对上述构建的最简单的GNN,我们如何在上面描述的任何任务中进行预测呢?这里我们仅仅考虑二进制分类的情况,但这个框架可以很容易地扩展到多类或回归的情况。 如果是对节点分类,我们只要在最后一层接一个线性类器就可以了: 但是上面的预测过程有点过于简单了,完全没有用到图的结构信息,我们在此基础上增加一个pooling操作,以增加它的边缘信息: 具体操作是把待预测节点的邻居节点以及全局的信息进行聚合再做预测,即将这些embedding向量加到一起得到一个新的向量,再输入到最后的线性分类器. 同理,如果我们只有节点相应边的信息的话,也可以用类似的方式pooling,然后得到节点的向量表示再输入分类器: 反之,如果我们只有节点的信息,那么也可以用边所连接的两个节点来pooling出边的向量,然后将器输入到分类器预测边的类型: 显然,不管是哪种任务,整个GNN的推理过程都是一样的,可以表示为这样一个端到端的过程: 不过,显而易见的,这个简单的GNN在分类前只是对每个向量进行了一个变换,而没有用到图结构的任何信息,虽然在最后做预测的时候做了一些pooling的聚合,但也始终没有用到adjacency的信息,因此这个GNN的作用相当有限,但是它为我们提供了一个图结构层变换和堆叠的基本思路. 针对上面最简单GNN的不足,我们可以在其中根据连通性增加更加复杂的变换从而引入整个图结构的信息,我们将这个过程称之为信息传递. 信息传递包含三个步骤: 这个过程有点类似于卷积操作,每个节点汇聚了其邻居的节点,经过多个层的变换,它将涵盖全图的信息. 于是我们可以将这个节点信息传递应用到上述的图变换过程中: 然后,我们发现它并没用用上边的信息,于是可以把边信息也加上,变成这样: 既然把边的信息加上了,那怎么可以漏掉全局信息呢,于是完整的信息传递就可以表示成这样: 以上,我们梳理了最简单的GNNs是怎么完成的,你应该已经对GNN有了一个基本的了解,就像学会了传统神经网络中最简单的全连接网络类似,关于GNN还有更多不同种类的更复杂的图需要取了解和学习,但你只要掌握了以上的思想,学习起来也是十分容易的.

什么叫神经网络?

枫舞给出基本的概念:一.一些基本常识和原理[什么叫神经网络?]人的思维有逻辑性和直观性两种不同的基本方式。逻辑性的思维是指根据逻辑规则进行推理的过程;它先将信息化成概念,并用符号表示,然后,根据符号运算按串行模式进行逻辑推理;这一过程可以写成串行的指令,让计算机执行。然而,直观性的思维是将分布式存储的信息综合起来,结果是忽然间产生想法或解决问题的办法。这种思维方式的根本之点在于以下两点:1.信息是通过神经元上的兴奋模式分布储在网络上;2.信息处理是通过神经元之间同时相互作用的动态过程来完成的。人工神经网络就是模拟人思维的第二种方式。这是一个非线性动力学系统,其特色在于信息的分布式存储和并行协同处理。虽然单个神经元的结构极其简单,功能有限,但大量神经元构成的网络系统所能实现的行为却是极其丰富多彩的。[人工神经网络的工作原理]人工神经网络首先要以一定的学习准则进行学习,然后才能工作。现以人工神经网络对手写“A”、“B”两个字母的识别为例进行说明,规定当“A”输入网络时,应该输出“1”,而当输入为“B”时,输出为“0”。所以网络学习的准则应该是:如果网络作出错误的的判决,则通过网络的学习,应使得网络减少下次犯同样错误的可能性。首先,给网络的各连接权值赋予(0,1)区间内的随机值,将“A”所对应的图象模式输入给网络,网络将输入模式加权求和、与门限比较、再进行非线性运算,得到网络的输出。在此情况下,网络输出为“1”和“0”的概率各为50%,也就是说是完全随机的。这时如果输出为“1”(结果正确),则使连接权值增大,以便使网络再次遇到“A”模式输入时,仍然能作出正确的判断。如果输出为“0”(即结果错误),则把网络连接权值朝着减小综合输入加权值的方向调整,其目的在于使网络下次再遇到“A”模式输入时,减小犯同样错误的可能性。如此操作调整,当给网络轮番输入若干个手写字母“A”、“B”后,经过网络按以上学习方法进行若干次学习后,网络判断的正确率将大大提高。这说明网络对这两个模式的学习已经获得了成功,它已将这两个模式分布地记忆在网络的各个连接权值上。当网络再次遇到其中任何一个模式时,能够作出迅速、准确的判断和识别。一般说来,网络中所含的神经元个数越多,则它能记忆、识别的模式也就越多。 ================================================= 枫舞推荐一个小程序:关于一个神经网络模拟程序的下载人工神经网络实验系统(BP网络) V1.0 Beta 作者:沈琦http://emuch.net/html/200506/de24132.html作者关于此程序的说明:从输出结果可以看到,前3条"学习"指令,使"输出"神经元收敛到了值 0.515974。而后3条"学习"指令,其收敛到了值0.520051。再看看处理4和11的指令结果 P *Out1: 0.520051看到了吗? "大脑"识别出了4和11是属于第二类的!怎么样?很神奇吧?再打show指令看看吧!"神经网络"已经形成了!你可以自己任意的设"模式"让这个"大脑"学习分辩哦!只要样本数据量充分(可含有误差的样本),如果能够在out数据上收敛地话,那它就能分辨地很准哦!有时不是绝对精确,因为它具有"模糊处理"的特性.看Process输出的值接近哪个Learning的值就是"大脑"作出的"模糊性"判别!=================================================枫舞推荐神经网络研究社区:人工神经网络论坛 http://www.youngfan.com/forum/index.phphttp://www.youngfan.com/nn/index.html(旧版,枫舞推荐)国际神经网络学会(INNS)(英文) http://www.inns.org/欧洲神经网络学会(ENNS)(英文) http://www.snn.kun.nl/enns/亚太神经网络学会(APNNA)(英文) http://www.cse.cuhk.edu.hk/~apnna日本神经网络学会(JNNS)(日文) http://www.jnns.org国际电气工程师协会神经网络分会http://www.ieee-nns.org/研学论坛神经网络 http://bbs.matwav.com/post/page?bid=8&sty=1&age=0人工智能研究者俱乐部 http://www.souwu.com/2nsoft人工神经网络中文站http://211.156.161.210:8888/2nsoft/index.jsp=================================================枫舞推荐部分书籍:人工神经网络技术入门讲稿(PDF) http://www.youngfan.com/nn/ann.pdf神经网络FAQ(英文) http://www.youngfan.com/nn/FAQ/FAQ.html数字神经网络系统(电子图书) http://www.youngfan.com/nn/nnbook/director.htm神经网络导论(英文) http://www.shef.ac.uk/psychology/gurney/notes/contents.html===============================================枫舞还找到一份很有参考价值的讲座<前向网络的敏感性研究>http://www.youngfan.com/nn/mgx.ppt是Powerpoint文件,比较大,如果网速不够最好用鼠标右键下载另存.=========================================================枫舞添言:很久之前,枫舞梦想智能机器人从自己手中诞生,SO在学专业的时候也有往这方面发展...考研的时候亦是朝着人工智能的方向发展..但是很不幸的是枫舞考研失败...SO 只好放弃这个美好的愿望,为生活奔波.希望你能够成为一个好的智能计算机工程师..枫舞已经努力的在给你提供条件资源哦~~
