论文赏析[NAACL19]无监督循环神经网络文法 (URNNG)（二）

Generative Model 上面的推理网络采样出了若干个句法树 z ，生成网络的目的就是计算它的联合概率。这个其实不难，在之前的RNNG论文笔记中，我已经大致讲过了，可以去复习一下：Recurrent Neural Network Grammarsgodweiyang.com这里稍稍做了一些改进。首先需要定义一个栈用来存放转移的历史状态，这里定义栈里放的元素为二元组，一个是stac...

论文赏析[NAACL19]无监督循环神经网络文法 (URNNG)（一）

介绍这篇是新鲜出炉的NAACL19的关于无监督循环神经网络文法（URNNG）的论文，在语言模型和无监督成分句法分析上都取得了非常不错的结果，主要采用了变分推理和RNNG。本文公式量较大，因此我也推了好久，算法也挺多的，首先上一张我推导的公式笔记：我这篇博客就不按照论文的顺序来讲了，就按照我上面这张笔记讲一讲我的理解吧，很多细节可能会忽略，请参见原文吧。首先对于无监督成分句法分析，常规做法就是学习....
