内容摘要
自然语言处理（NLP）为深度学习应用程序提供了大部分可用的数据，而TensorFlow是目前可用的重要的深度学习框架。《TensorFlow自然语言处理》将TensorFlow和NLP结合在一起，为你提供处理今天的数据流中大量非结构化数据的宝贵工具，并将这些工具应用到特定的NLP任务。
Thusshan Ganegedara首先为你讲解NLP和TensorFlow基础。然后你将学习如何使用Word2vec（包括不错扩展）来创建将词序列转换为可以被深度学习算法访问的向量的词嵌入。卷积神经网络（13NN）和递归神经网络（RNN）等经典深度学习算法的相关章节展示了句子分类和语言生成等重要的NLP任务。你将学习如何将长短期记忆（LsTM）等高性能RNN模型应用于NLP任务。你还将探索神经机器翻译并实现一个神经机器翻译程序。
