为了解决这个问题,首先需要知道BLEU值是如何计算出来的. BLEU全称是Bilingual Evaulation Understudy.其意思是双语评估替补.所谓Understudy(替补),意思是代替人进行翻译结果的评估. BLEU的思想基于Count based Model,尽管它并不完美,但它提供了一种非常有效的以单一数字指标评估机器翻译结果的方法. 下面以一个例子说明BLEU的计算. 假如正确的翻译参考(2)个是: The cat is on the desk. There is a

最近因为要做一个title压缩的任务,所以调研了一些text summary的方法. text summary 一般分为抽取式和生成式两种.前者一般是从原始的文本中抽取出重要的word or sentence,然后按照一定的语法或者句法进行组合,从而对原始的文本进行压缩.再文本摘要的早期,基本都是这个思路,代表性的方法是textrank.所谓生成式的方法,就是试图让机器理解原始的文本,从而自己归纳出原始文本的摘要,给出的结果(词语或者句子)可能是原始文本中没有出现过的,这也是其与抽取
26 THINGS I LEARNED IN THE DEEP LEARNING SUMMER SCHOOL In the beginning of August I got the chance to attend the Deep Learning Summer School in Montreal. It consisted of 10 days of talks from some of the most well-known neural network researchers. Du
2 Natural Language Processing & Word Embeddings 2.1 Word Representation(单词表达) vocabulary,每个单词可以使用1-hot表示,写作\(O^{5391}\)之类,上标可以变.只是用1-hot,不能知道任意两个单词的关系,例如man/woman;king/queen;apple/orange. 特征化表示:词嵌入(Featurized representation:word embedding).一个特征,使用-1到
Sequence Models This is the fifth and final course of the deep learning specialization at Coursera which is moderated by deeplearning.ai Here are the course summary as its given on the course link: This course will teach you how to build models for n
About this Course This course will teach you how to build models for natural language, audio, and other sequence data. Thanks to deep learning, sequence algorithms are working far better than just two years ago, and this is enabling numerous exciting

Lesson 5 Sequence Models 这篇文章其实是 Coursera 上吴恩达老师的深度学习专业课程的第五门课程的课程笔记. 参考了其他人的笔记继续归纳的. 符号定义 假如我们想要建立一个能够自动识别句中人名地名等位置的序列模型,也就是一个命名实体识别问题,这常用于搜索引擎.命名实体识别系统可以用来查找不同类型的文本中的人名.公司名.时间.地点.国家名和货币名等等. 我们输入语句 "Harry Potter and Herminoe Granger invented a new s
Attention Is All You Need Abstract The dominant sequence transduction models are based on complex recurrent or convolutional neural networks that include an encoder and a decoder. 显性序列转换模型基于复杂的递归或卷积神经网络,包括编码器和解码器. The best performing models also conn
