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…

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…

Sequence to Sequence models basic sequence-to-sequence model: basic image-to-sequence or called image captioning model: but there are some differences between how you write a model like this to generate a sequence, compared to how you were synthesizi…

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…

LSTM’s in Pytorch Example: An LSTM for Part-of-Speech Tagging Exercise: Augmenting the LSTM part-of-speech tagger with character-level features Sequence models are central to NLP: they are models where there is some sort of dependence through time be…

第三周 序列模型和注意力机制(Sequence models & Attention mechanism) 基础模型(Basic Models) 在这一周,你将会学习 seq2seq(sequence to sequence)模型,从机器翻译到语音识别,它们都能起到很大的作用,从最基本的模型开始.之后你还会学习集束搜索(Beam search)和注意力模型(Attention Model),一直到最后的音频模型,比如语音. 现在就开始吧,比如你想通过输入一个法语句子,比如这句 "Jane…

第一周 循环序列模型(Recurrent Neural Networks) 为什么选择序列模型?(Why Sequence Models?) 在本课程中你将学会序列模型,它是深度学习中最令人激动的内容之一.循环神经网络(RNN)之类的模型在语音识别.自然语言处理和其他领域中引起变革.在本节课中,你将学会如何自行创建这些模型.我们先看一些例子,这些例子都有效使用了序列模型. 在进行语音识别时,给定了一个输入音频片段 \(X\),并要求输出对应的文字记录 \(Y\).这个例子里输入和输出数据都是序列…

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…
