其他常见神经网络包括径向基函数网络(Radial Basis Function, RFB), ART(Adaptive Resonance Theory)网络, SOM(Self-Organizing Map)网络,递归神经网络(Recurrent Neural Networks) 误差反向传播法(Error BackPropagation, BP)是迄今最成功的神经网络学习算法,详情参见误差反向传播。标准BP算法每次针对一个训练样本来更新模...
1. 语言模型 语言模型 (Language Models) 是语音识别系统中的重要组成部分,在前面章节中已多次提过语音识别的核心公式 (1)P(W|O)=p(O|W)P(W)p(O)∝p(O|W)P(W) 在n 元语法 (n-gram language model) 模型一节中首次讨论了语言模型部分P(W),语言模型用于计算一段词序列W={w1,w2,…,wn}的概率 ...
modeling and neural networks is to be aware of what has been achieved in this multidisciplinary field of research. This book sets out to create such awareness. Leading experts develop in twelve chapters the key topics of neural structures and functions, dynamics of single neurons, oscillations in...

There have been numerous applications of convolutional networks going back to the early 1990s, starting with time-delay neural networks for speech recognition and document reading. The document reading system used a ConvNet trained jointly with a probabilistic model that implemented language constraints....
这个式子的目的就是,前半段是直接生成,后半段是直接从翻译记忆中抽取,综合这个概率决定生成和抽取~。这个式子的具体思路,大家可以看看这篇论文【论文阅读】Get To The Point: Summarization with Pointer-Generator Networks。 我们用\phi代表生成模型全部的参数。
