Word2vec 主要有两种形式，CBOW 和Skip-gram，其中CBOW是通过上下文context来预测当前位置词，SKip-gram则是通过当前词来预测上下文 Fake Task word2vec 实际上分为两部分，1，建立模型，2，通过模型获取词的嵌入向量（隐层参数）。整个过程与自编码器的思想类似，即基于训练数据训练一个神经网络，模型训练好后，并不会用这个模型处理后续的任务，真正需要的是这个模型学到的参数，如隐层的权重矩阵，基于训练数据建模的过程叫“Fake Task”，意味着建模并不是我们最终的目的。 Train 如何训练我们的神经网络模型？假如我们有一个句子“ The dog barked at the mailman”。 首先，我们选择句子中一个词作为我们的input word， 如 dog 然后，我们需要定义一个skip_window参数，来指定上下文的大小，即input word 一侧选取词的数量，假如skip_window=2,那将从dog出发向左右两个方向取最近的两个word，即（the, dog,barked,at)，此时的span = skip_window * 2 + 1 = 5 另一个需要定义的参数是num_skips，即从上下文中选取多少个word来作为output word，这个参数应该小于等于2 * skip_window，即最多将所有上下文都作为output，但是不能重复。如设置num_skips = 2,此时从上下文选取2个词作为output，如（the， barked），最终我们将得到两组训练数据（dog, the) (dog, barked) 神经网络将基于这些训练数据输出一个概率分布，这个概率分布代表着在输入数据下，词典中每个词是output的概率。如拿数据（dog， barked）来训练，则模型将会告诉我们每个单词是"barked"的概率大小。 模型的输出概率代表着词典中每个单词有多大可能性跟input word同时出现。举个栗子，如果我们向神经网络模型中输入一个单词“Soviet“，那么最终模型的输出概率中，像“Union”， ”Russia“这种相关词的概率将远高于像”watermelon“，”kangaroo“非相关词的概率。因为”Union“，”Russia“在文本中更大可能在”Soviet“的窗口中出现。 我们将通过给神经网络输入文本中成对的单词来训练它完成上面所说的概率计算。下面的图中给出了一些我们的训练样本的例子。我们选定句子“The quick brown fox jumps over lazy dog”，设定我们的窗口大小为2（window_size = 2），也就是说我们仅选输入词前后各两个词和输入词进行组合。下图中，蓝色代表input word，方框内代表位于窗口内的单词。 模型将会从每队单词出现的次数中习得统计结果，模型可能会得到更多的（"soviet"， ‘union"）样本对，而（soviet， dog）这样的组合看到的很少。因此，当模型训练完成后，给定一个单词 soviet，输出结果中union 或者russia会比dog有更高的概率。 输入 常用做法是用训练文档构建词汇表，然后再对单词进行0ne-hot编码。 编码后的向量，形如dog = [0, 0, 1, 0, …0], 如果词汇表大小为10000， 那这个向量包含了10000的概率，即为当前词为输入的概率 下图是神经网络结构： 我们基于成对的单词来对神经网络进行训练， 训练样本是（input word， output word）这样的单词对，input word 和 output word都是one-hot编码的向量，最终的模型输出是一个概率分布。 隐层 如果我们想要用300个特征来表示一个词（即每个词是300维的向量），即隐层有300个神经元，隐层的权重为10000 * 300的矩阵，下图中的左右两个图代表了不同角度看隐层权重，左图中每列代表一个10000维的词向量与隐层单个神经元的连接权重，右图每行代表了一个单词的词向量。 我们最终的目标就是学习这个隐层权重矩阵。 输入被one-hot编码后，实际上只有一个位置不为0，所以这个向量相当稀疏，那如果我们将1 10000的向量与10000 300的矩阵相乘，相当消耗计算资源，为了高效计算，仅仅会选择矩阵中对应的向量中纬度为1的索引行 即实际不会进行矩阵乘法计算，而是根据输入向量中不为0 的维度去索引。这样模型中的隐层权重矩阵便成了一个查找表（lookup table），输出就是输入单词的嵌入词向量 输出层 隐层的输出是一个1*300的向量，而输出层是一个softmax回归分类器，他的每个结点将会输出一个0-1之间的值（概率），而结点的概率之和为1. 我们会发现Word2Vec模型是一个超级大的神经网络（权重矩阵规模非常大）。 举个栗子，我们拥有10000个单词的词汇表，我们如果想嵌入300维的词向量，那么我们的输入-隐层权重矩阵和隐层-输出层的权重矩阵都会有 10000 x 300 = 300万个权重，在如此庞大的神经网络中进行梯度下降是相当慢的。更糟糕的是，你需要大量的训练数据来调整这些权重并且避免过拟合。百万数量级的权重矩阵和亿万数量级的训练样本意味着训练这个模型将会是个灾难（太凶残了）。 Word2Vec的作者在它的第二篇论文中强调了这些问题，下面是作者在第二篇论文中的三个创新： 事实证明，对常用词抽样并且对优化目标采用“negative sampling”不仅降低了训练过程中的计算负担，还提高了训练的词向量的质量。 word pairs and phases 一些单词组合的含义和拆开以后具有完全不同的意义，比如 New York，单独的New 和York无法表达这个词组的含义。因此，应该把New York作为一个单独的词组来生成其词向量。 对高频词抽样 对于高频词，如 the ，按上面的处理方式会有两个问题： 如果直接删除掉这些高频词，会有两个问题 1.删除后，the这个单词永远也不会出现在我们的上下文窗口 2.训练样本会减少 所以word2vec 采用抽样的方式来解决这种高频词问题。他的基本思想是：对于我们在训练原始文本中遇到的每一个单词，他们都有一定概率被我们从文本中删除掉，而这个被删除的概率与单词的频率有关。 wi 是一个单词，Z(wi)是这个单词在所有预料中出现的频次。P(wi)是被保留的概率。 负采样 训练一个神经网络意味着要输入训练样本并且不断的调整神经元的权重，不断提高对目标的准确预测。而vocabulary的大小决定了skip-gram神经网络将拥有大规模的权重矩阵，所有的这些权重需要通过我们数以亿计的样本来训练调整，非常消耗计算资源，并且实际中会非常慢。 负采样解决了这个问题，不同于原本每个训练样本更新所有权重，负采样每次让一个训练样本仅仅更新一部分权重，减小计算量。 对于训练样本（fox，quick），都是经过one-hot编码的，当vocabulary的大小为10000时，我们期望输出对应的quick单词的那个神经元的输出是1，其余9999个都是0，这9999个输出为0的神经元所对应的单词称为negative word 隐层-输出层拥有300 10000的权重，而负采样时，我们仅仅更新quick 和我们选择的其他5个negative word的结点对应的权重，共6个神经元，300 6 = 1800 个权重，相当于只计算了0.06%的权重，计算效率大大提高。 其中f(wi)代表每个单词出现的频次，p(wi)代表被选中的概率。 负采样的C语言实现非常的有趣。unigram table有一个包含了一亿个元素的数组，这个数组是由词汇表中每个单词的索引号填充的，并且这个数组中有重复，也就是说有些单词会出现多次。那么每个单词的索引在这个数组中出现的次数该如何决定呢，由公式P(wi) * table_size，也就是说计算出的负采样概率*1亿=单词在表中出现的次数。 有了这张表以后，每次去我们进行负采样时，只需要在0-1亿范围内生成一个随机数，然后选择表中索引号为这个随机数的那个单词作为我们的negative word即可。一个单词的负采样概率越大，那么它在这个表中出现的次数就越多，它被选中的概率就越大。

Brown夫妇打算去美国度假。他们有一只叫Blackie的狗，却不能同往。于是夫妇决定在度假前找个能寄养的好地方。假期结束返回英国时已经很晚了，他们想寄养狗狗的地方可能已经关门了，于是决定在第二天前往。 第二天一早布朗就驱车把狗狗叫了回来。当他带着狗狗回到家里时，对妻子说：“知道吗亲爱的，它一定是喜欢上那个地方了。一路上它不停的在叫。像是要说什么。”布朗夫人仔细看了看狗狗，说道：“没错，亲爱的，它不是想告诉你它有多喜欢那个地方。它只是想告诉你，你牵错了，它不是Blackie”.

　　作为老师,应根据学生的知识水平与理解能力,把教育的话题与隐含着教育内容的美文相互整合,把教育内容融合在相关美文中,引导学生在感悟美文之余受到思想的感染、熏陶与启迪。我整理了有关于狗狗的英语美文，欢迎阅读! 　　有关于狗狗的英语美文篇一 　　The origin of dogs 　　Have you ever taken a good look at your dog and wondered, where did this creature come from? 　　你是否曾仔细观察过你的狗狗,迫切想知道汪星人这种生物到底来自哪里? 　　Sure, you know your dog came from the local shelter or a pet store, but what about before that? 　　当然,你清楚它们是来自当地避难所或宠物商店,但是在这之前呢? 　　If you were able to trace your dog"s lineage back to its origins, what would you find? 　　如果你能够跟踪狗狗的血统回到它的起源,你会有何发现? 　　Until recently, scientists believed that domestic dogs originated in the Middle East. 　　直到最近,科学家们相信国内的狗起源于中东地区。 　　But reports suggest that almost all domestic dogs began in East Asia as the offspring of three lineages. 　　但报告显示,几乎所有国内的狗都是东亚血统三代之后。 　　Virtually all domesticated dogs in the United States descend from dogs brought over by ancient people that crossed the Bering land bridge from Asia to North America. 　　几乎所有美国家养的狗狗都是从亚洲到北美穿过白令海峡大陆桥的古代人们带过来繁衍生息下来的子孙。 　　Although the New World had a healthy wolf population that might have given rise to a New World strain of domesticated dogs, by and large these ancient immigrants stuck with the dogs of Asian origin. 　　虽然新世界繁殖良好的狼可能会为国内狗狗带来新的压力,但总的来说,这些古代移民无法摆脱自己的亚裔血统。 　　How, you may wonder, have scientists come to these conclusions? 　　怎么样,你是不是会觉得奇怪,科学家哪来的这些结论? 　　The same way forensic specialists increasingly solve crimes-through DNA evidence. 　　这就如同法医专家通过DNA证据破案一样。 　　Since mitochondria are cellular elements passed from mother to pup, mitochondrial DNA readily reveal genetic footprints stretching back into prehistoric times. 　　线粒体是通过狗母亲传递的细胞元素,线粒体DNA揭示伸展回到史前时代的遗传印记。 　　Scientists from the Smithsonian Institution in Washington, D.C. collected DNA samples from the remains of ancient Old World dogs, ancient New World dogs, and ancient New World wolves. 　　华盛顿特区史密森学会的科学家们从古老旧世界的狗狗,古代新世界及古代的狼的遗体中收集DNA样本。 　　Test showed decisively that the New World dogs were genetically more similar to Old World dogs than to New World wolves, effectively proving that the dogs we save from local shelters originally hail from the far East rather than the woods of North America. 　　试验表明新世界狗狗的基因相比新世界的狼更类似于旧世界,这有力的证明我们从当地避难所中救助的狗狗最初来自远东而非北美的森林。 　　有关于狗狗的英语美文篇二 　　Fly Dogs 　　Air travel makes some people very nervous. The crowds, the noise and flying itself can causeunease. But there are classes people can take to help them defeat the fear of flying. And, nowCaty Weaver tells us about similar training for service dogs that suffer the same problem. 　　Service dogs almost never leave the side of the people they care for. You will see them workingon buses, trains and other public transport systems. But the busy environment found at anairport can trouble even the best trained working dog. 　　People with disabilities depend on their dogs. They want the animals to safely guide themthrough security areas. They also need to the dogs to remain calmly on duty on the airplane,even when the flying is not smooth. This takes special training. The Air Hollywood K9 FlightSchool is one place where such help can be found. 　　The school has a piece of equipment that provides the sights, sounds and even the feel of anairplane in flight. It is called a flight simulator. The simulator was built for filming airplanescenes in movies. 　　Milsa Grant of New York holds her dog Lulu Madonna, as she waits to check-in atLaGuardia Airport in New York. (File photo) 　　Sandy Alexander lives in Newport Beach, California. He has a disability that requires his two-year-old dog, Doc, to be always at his side. Mr. Alexander took the dog to the flight school toget him ready for plane trips. He says Doc did not like the bumpy part of the flight simulation. 　　"When that started he was pretty agitated and looked up at me and wasn"t sure what wasgoing on, and I think we are going to be prepared the next time it happens." 　　Dog trainer Mary Segall is with Canine Companions for Independence. It provides dogs forpeople with disabilities. Ms. Segall says successful training is based on a simple rule:preparation. 　　"Dogs need to be exposed gradually and repetitively to stimulation, to the environment, toloud noises, to sounds and other dogs so that when this experience happens to them on adaily basis, they"re able to act in a way that they"re used to acting and that they don"t getexcitable." 　　Stacy Huckeba"s nine-month-old dog, Striker, is still in training to be a guide dog. 　　"I don"t fly a lot so I don"t know a lot, but, so I don"t know the routine myself. So with a dog Iwould have been lost." 　　Dog owners who attended the training at Air Hollywood K9 Flight School say they now feelmuch more at ease about future flights. Their dogs also seem ready for takeoff. 　　有关于狗狗的英语美文篇三 　　狗狗就算再温顺 也会羡慕嫉妒恨 　　Any dog owner would testify that dogs are just as prone to jealousy as humans. 　　任何狗主人都能作证，狗狗简直和人一样容易嫉妒。 　　But can one really compare Othello"s agony to Roscoe"s pique? 　　但真的有人能把罗斯科(Roscoe)的愤懑与奥赛罗(Othello)的痛苦相提并论吗? 　　The answer, according to Christine Harris, a psychologist at the University of California, San Diego, is that if you are petting another dog, Roscoe is going to show something that Dr. Harris thinks is a form of jealousy, even if not as complex and twisted as the adult human form. 　　加州大学圣迭戈分校(University of California, San Diego)的心理学家克里斯蒂娜·哈里斯(Christine Harris)表示，答案是，如果你抚摸另一只狗，罗斯科会有某种表现。哈里斯博士认为，这种表现是嫉妒的一种形式，尽管这种形式不像成年人类的嫉妒形式那么复杂、扭曲。   　　Other scientists agree there is something going on, but not all are convinced it is jealousy. And Roscoe and the rest of his tribe were, without exception, unavailable for comment. 　　其他一些科学家也认同这种情形下会出现某种情况，但并不都相信那是嫉妒。而罗斯科和他的同类，无一例外均不便发表评论。 　　Dr. Harris had been studying human jealousy for years when she took this question on, inspired partly by the antics of her parents" Border collies. When she petted them, “one would take his head and knock the other"s head away,” she said. It certainly looked like jealousy. 　　在遇到这个问题时，哈里斯博士已经对人类的嫉妒情绪进行了多年研究。当时，她部分是受了父母的边境牧羊犬表现出的怪异行为的启发。她说，当她抚摸他们时，“其中一只会用头把另外一只的头挤开”。这种情形看上去当然像嫉妒了。 　　But having studied humans, she was aware of different schools of thought about jealousy. Some scientists argue that jealousy requires complex thinking about self and others, which seems beyond dogs" abilities. Others think that although our descriptions of jealousy are complex, the emotion itself may not be that complex. 　　但因为已经对人类进行了研究，她了解有关嫉妒的不同思想流派。一些科学家认为，嫉妒要求有能力对自身和他人进行复杂思考，这似乎超出了狗狗的能力。其他一些人则认为，尽管我们对嫉妒的描述颇为复杂，但这种情感本身或许并不复杂。 　　Dog emotions, as owners perceive them, have been studied before. In one case, Alexandra Horowitz, a cognitive scientist who is an adjunct associate professor at Barnard College and the author of “Inside of a Dog,” found that the so-called guilty look that dogs exhibit seemed to be more related to fear of punishment. 　　以前就有人研究过主人眼中狗狗的情感。在其中一项研究中，著有《一只狗的内心》(Inside of a Dog)的认知科学家、巴纳德学院(Barnard College)客座副教授亚历山德拉·霍罗威茨(Alexandra Horowitz)发现，狗狗表现出来的所谓的内疚表情似乎与害怕受到惩罚更相关。 　　Dr. Harris ventured into the tricky turf of dog emotion by devising a test based on work done with infants. 　　哈里斯博士以针对孩子的研究工作为基础，设计了一个试验，大胆进入了狗的情感这个棘手领域。 　　When dog owners petted and talked to a realistic stuffed dog that barked and whined, the people"s own dogs came over, pushed the person or the stuffed dog, and sometimes barked. After the experiment, many of the dogs sniffed the rear end of the stuffed dog, suggesting, Dr. Harris said, that the dogs thought it might be real. 　　当狗主人抚摸一只逼真的、能吠叫并发出呜呜声的填充玩具狗，并与其说话时，他们自己的狗会走过来，推自己的主人或那只玩具狗，有时还会大叫。试验结束后，许多狗狗会嗅那只填充玩具狗的臀部。哈里斯博士称，这表明，那些狗狗以为玩具狗可能是一只真狗。 　　Dr. Harris also recorded what happened as the owners petted and talked to a jack-o"-lantern and read a children"s book aloud, to see if any old distraction would provoke a reaction. The dogs paid little attention to the jack-o"-lantern and very little to the book. 　　为了看看随便什么通常分散注意力的事情会不会让它们有所反应，哈里斯还记录了狗主人在抚摸南瓜灯笼并和它说话，以及大声朗读儿童读物时发生的情况。那些狗少有注意灯笼的，对那本书，狗狗的关注度则更小。 　　Dr. Harris concluded, in a paper in PLoS One written with Caroline Prouvost, also at the University of California, San Diego, that the dogs showed a “primordial” form of jealousy, not as complex as the human emotion, but similar in that there is a social triangle and the dog is trying to make sure it, not the rival, receives the attention. 　　在与同在加州大学圣迭戈分校任职的卡罗琳·普鲁沃(Caroline Prouvost)共同撰写，并发表在《公共科学图书馆·综合》(PLOS One)的一篇文章中，哈里斯得出结论称，那些狗表现出了一种“原始”形式的嫉妒，不像人类的嫉妒那么复杂。但它也是发生在一种社会三角关系之中，狗狗会尝试确定获得关注的是自己，而不是对手，因此这种情感与人类的嫉妒类似。 　　Other scientists had mixed reactions to the work. Dr. Horowitz said she admired the goal but thought the researchers had not shown that the behaviors observed actually indicated jealousy. 　　其他科研人员对这项研究的反响各异。霍罗威茨博士说，她很欣赏该研究的目标，但她认为，研究者没能证明，被观察到的行为真的代表嫉妒。 　　“What can be shown is that dogs seem to want an owner"s attention when there is attention being given out,” she said. “This study confirms that.” 　　“可以被证明的是，当主人向外界给予关注的时候，狗狗似乎想要得到这种关注，”她说，“这项研究证实了这一点。” 　　Sybil Hart, at Texas Tech, who has studied jealousy in infants, said she thought the research was “very well done and makes a very compelling argument.” 　　德克萨斯理工大学的西比尔·哈特(Sybil Hart)曾经研究过婴儿的嫉妒心理。哈特说，她认为这项研究“做得很出色，观点令人信服”。 　　If one sees jealousy in babies and dogs, she said, “to some degree, it"s innate,” which would be important to know for attempts to manage human jealousy. 　　哈特说，如果人们发现了婴儿和狗狗的嫉妒之心，“在一定程度上，这是天生的”。了解这一点对于管理成人的嫉妒情绪十分重要。 　　“Over all, trying to make it go away has not been very successful,” Dr. Hart said. “We are trying to eliminate jealousy, and scientists are saying maybe we should try to understand it better.” 　　“总的来说，消除嫉妒心理的努力并不是非常成功，”哈特博士说。“我们正努力消除嫉妒情绪，而科学家告诉我们，或许我们应该试着更好地理解它。” 　　Jealousy, Dr. Harris wrote in the study, is “the third leading cause of nonaccidental homicide across cultures.” 　　哈里斯在研究中写道，嫉妒“在许多文化中都是故意杀人案的第三大诱因”。 　　Whatever the dogs" behavior is called, said Brian Hare, a director of the Duke Canine Cognition Center at Duke University, there are practical implications for their owners. 　　杜克大学杜克犬科动物认知研究中心(Duke Canine Cognition Center at Duke University)的主任布赖恩·黑尔(Brian Hare)说，无论犬类的这种行为被称作什么，对他们的主人而言，都会存在一些实实在在的影响。 　　“Attention seeking can lead to jealousylike behavior in dogs that includes aggression in some cases,” he said. “So for dogs with suspected aggression problems, it may be important to avoid situations where they feel ignored.” 　　“寻求关注可以引发狗狗类似于嫉妒的表现，比如有时候出现攻击性，”他说。“因此，对于可能有攻击性问题的狗狗来说，避免让他们感到被忽略也许十分重要。”

这个故事是编的,原文如下 When George was about six years old,he was made the wealthy master of a hatchet of which,like most little boys,he was extremely fond.He went about chopping everything that came his way. One day,as he wandered about the garden amusing himself by hacking his mother"s pea sticks,he found a beautiful,young English cherry tree,of which his father was most proud.He tried the edge of his hatchet on the trunk of the tree and barked it so that it died. Some time after this,his father discovered what had happened to his favorite tree.He came into the house in great anger,and demanded to know who the mischievous person was who had cut away the bark.Nobody could tell him anything about it. Just then George,with his little hatchet,came into the room. "George,"" said his father,"do you know who has killed my beautiful little cherry tree yonder in the garden?I would not have taken five guineas for it!"" This was a hard question to answer,and for a moment George was staggered by it,but quickly recovering himself he cried: "I cannot tell a lie,father,you know I cannot tell a lie!I did cut it with my little hatchet."" The anger died out of his father"s face,and taking the boy tenderly in his arms,he said: "My son,that you should not be afraid to tell the truth is more to me than a thousand trees!Yes - though they were blossomed with silver and had leaves of the purest gold!

The Little Red HenOnce upon a time, there was a little red hen who lived on a farm . She was friends with a lazy dog , a sleepy cat , and a noisy yellow duck . One day the little red hen found some seeds on the ground. The little red hen had an idea. She would plant the seeds . The little red hen asked her friends, "Who will help me plant the seeds ?" "Not I," barked the lazy dog ."Not I," purred the sleepy cat ."Not I," quacked the noisy yellow duck . "Then I will," said the little red hen . So the little red hen planted the seeds all by herself. When the seeds had grown, the little red hen asked her friends, "Who will help me cut the wheat ?""Not I," barked the lazy dog ."Not I," purred the sleepy cat ."Not I," quacked the noisy yellow duck . "Then I will," said the little red hen . So the little red hen cut the wheat all by herself. When all the wheat was cut, the little red hen asked her friends, "Who will help me take the wheat to the mill to be ground into flour ?""Not I," barked the lazy dog ."Not I," purred the sleepy cat ."Not I," quacked the noisy yellow duck . "Then I will," said the little red hen . So the little red hen brought the wheat to the mill all by herself, ground the wheat into flour , and carried the heavy sack of flour back to the farm . The tired little red hen asked her friends, "Who will help me bake the bread ?" "Not I," barked the lazy dog ."Not I," purred the sleepy cat ."Not I," quacked the noisy yellow duck . "Then I will," said the little red hen . So the little red hen baked the bread all by herself. When the bread was finished, the tired little red hen asked her friends, "Who will help me eat the bread ?" "I will," barked the lazy dog ."I will," purred the sleepy cat ."I will," quacked the noisy yellow duck . "No!" said the little red hen . "I will." And the little red hen ate the bread all by herself
