第一周 循环序列模型(Recurrent Neural Networks) 1.1 为什么选择序列模型?(Why Sequence Models?) 1.2 数学符号(Notation) 这个输入数据是 9 个单词组成的序列,所以会有 9 个特征集和来表示这 9 个 单词,并按序列中的位置进行索引,用\(…
Improvise a Jazz Solo with an LSTM Network Welcome to your final programming assignment of this week! In this notebook, you will implement a model that uses an LSTM to generate music. You will even be able to listen to your own music at the end of th…
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…
Expected OutputTrigger Word Detection Welcome to the final programming assignment of this specialization! In this week's videos, you learned about applying deep learning to speech recognition. In this assignment, you will construct a speech dataset a…
Building your Recurrent Neural Network - Step by Step Welcome to Course 5's first assignment! In this assignment, you will implement your first Recurrent Neural Network in numpy. Recurrent Neural Networks (RNN) are very effective for Natural Language…
Character level language model - Dinosaurus land Welcome to Dinosaurus Island! 65 million years ago, dinosaurs existed, and in this assignment they are back. You are in charge of a special task. Leading biology researchers are creating new breeds of…
[解释] It is appropriate when every input should be matched to an output. [解释] in a language model we try to predict the next step based on the knowledge of all prior steps. [解释] Γu is a vector of dimension equal to the number of hidden units in the LS…
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…
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…
