吴恩达《深度学习》-第五门课 序列模型(Sequence Models)-第二周 自然语言处理与词嵌入（Natural Language Processing and Word Embeddings）-课程笔记

第二周 自然语言处理与词嵌入(Natural Language Processing and Word Embeddings) 2.1 词汇表征(Word Representation) 词汇表示,目前为止一直都是用词汇表来表示词,上周提到的词汇表,可能是 10000 个单词,我们一直用 one-hot 向量来表示词.这种表示方法的一大缺点就是它把每个词孤立起来,这样使得算法对相关词的泛化能力不强. 换一种表示方式会更好,如果不用 one-hot 表示,而是用特征化的表示来表示每个词,man,w…

Neural Machine Translation Welcome to your first programming assignment for this week! You will build a Neural Machine Translation (NMT) model to translate human readable dates ("25th of June, 2009") into machine readable dates ("2009-06-25…

课程五(Sequence Models)，第二 周（Natural Language Processing & Word Embeddings） —— 2.Programming assignments：Emojify

Emojify! Welcome to the second assignment of Week 2. You are going to use word vector representations to build an Emojifier. Have you ever wanted to make your text messages more expressive? Your emojifier app will help you do that. So rather than wri…

课程五(Sequence Models)，第二 周（Natural Language Processing & Word Embeddings） —— 1.Programming assignments：Operations on word vectors - Debiasing

Operations on word vectors Welcome to your first assignment of this week! Because word embeddings are very computionally expensive to train, most ML practitioners will load a pre-trained set of embeddings. After this assignment you will be able to: L…
