作者:zhbzz2007 出处:http://www.cnblogs.com/zhbzz2007 欢迎转载,也请保留这段声明.谢谢! 这是RNN教程的第三部分. 在前面的教程中,我们从头实现了一个循环神经网络,但是并没有涉及随时间反向传播(BPTT)算法如何计算梯度的细节.在这部分,我们将会简要介绍BPTT并解释它和传统的反向传播有何区别.我们也会尝试着理解梯度消失问题,这也是LSTM和GRU(目前NLP及其它领域中最为流行和有用的模型)得以发展的原因.梯度消失问题最早是由 Sepp Hochr…

首先看这个自动求导的参数: grad_variables:形状与variable一致,对于y.backward(),grad_variables相当于链式法则dz/dx=dz/dy × dy/dx 中的 dz/dy.grad_variables也可以是tensor或序列. retain_graph:反向传播需要缓存一些中间结果,反向传播之后,这些缓存就被清空,可通过指定这个参数不清空缓存,用来多次反向传播. create_graph:对反向传播过程再次构建计算图,可通过backward of b…

第1章 从随机变量采样 研究者提出的概率模型对于分析方法来说通常比较复杂,研究者处理复杂概率模型时越来越依赖计算.数值方法,通过使用计算方法,研究者就不用对一些分析技术做一些不现实的假设(如正态性和独立性). 大多数近似技术的关键是能够从分布中采样.需要采样来预测一个特别的模型在一些情景下是什么样的,找到在实验数据上应用模型的隐变量(参数)的合适值.大部分计算采样方法把从复杂分布采样的问题转化为简单采样分布的子问题.本章我们将介绍两种采样方法:逆变换方法和拒绝采样.这些方法适用于大多数单变量单值…
