Sequence Model-week3编程题1-Neural Machine Translation with Attention

1. Neural Machine Translation 下面将构建一个神经机器翻译(NMT)模型,将人类可读日期 ("25th of June, 2009") 转换为机器可读日期 ("2009-06-25"). 使用 attention model. from keras.layers import Bidirectional, Concatenate, Permute, Dot, Input, LSTM, Multiply from keras.layers…

对Neural Machine Translation by Jointly Learning to Align and Translate论文的详解

读论文 Neural Machine Translation by Jointly Learning to Align and Translate 这个论文是在NLP中第一个使用attention机制的论文.他们把attention机制用到了神经网络机器翻译(NMT)上.NMT其实就是一个典型的sequence to sequence模型,也就是一个encoder to decoder模型,传统的NMT使用两个RNN,一个RNN对源语言进行编码,将源语言编码到一个固定维度的中间向量,然后在使用一…

Effective Approaches to Attention-based Neural Machine Translation(Global和Local attention)

这篇论文主要是提出了Global attention 和 Local attention 这个论文有一个译文,不过我没细看 Effective Approaches to Attention-based Neural Machine Translation 中英文对照翻译 - 一译的文章 - 知乎 https://zhuanlan.zhihu.com/p/38205832 看这个论文的时候我主要是从第三小节开始看起的,也就是 attention-based models 我们基于attentio…

神经机器翻译 - NEURAL MACHINE TRANSLATION BY JOINTLY LEARNING TO ALIGN AND TRANSLATE

论文:NEURAL MACHINE TRANSLATION BY JOINTLY LEARNING TO ALIGN AND TRANSLATE 综述 背景及问题 背景: 翻译: 翻译模型学习条件分布后,给定一个源句,通过搜索最大条件概率的句子,可以生成相应的翻译. 神经网络翻译:两个组件:第一个:合成一个源句子x:第二个:解码一个目标句子y. 问题:固定长度向量是编码器 - 解码器架构性能提升的瓶颈. 本文主要思想 本文提出:允许模型自动(软)搜索与预测目标单词相关的源句 --- 扩展的编码器…
