Hochreiter(1991)和Bengio等(1994)确定了建模长序列的一些基本数学困难,在第10.7节中有描述。Hochreiter和Schmidhuber(1997)引入了长短期记忆(LSTM)网络来解决这些困难。如今,LSTM被广泛用于许多序列建模任务,包括Google的许多自然语言处理任务。 第二波神经网络研究持续到90年代中期。基于神经网络和其他AI技术的企业开始提...
LSTM是比GRU更加广泛的RNN版本,并且性能更加的好,LSTM中没有判断相关性的gamma r门,在LSTM中两个门分别负责更新、和遗忘选择。 还有一个输出门 下图是LSTM的公式、一个block,及简单的网络连接,只要学习到合适的更新门、遗忘门,那么LSTM很容易直接将前面输出传输到最后的输出得到C_3 = C_0,这也是为什么LSTM包括G...

The critical component of the LSTM28is the memory cell and the gates (including the forget gate,29but also the input gate). The contents of the memory cell are modulated by the input gates and forget gates.30Assuming that both of these gates are closed, the contents of the memory cell w...
Explore book 1.1.2 Deep learning Deep learning is the term often used with AI, but not many people understand what it actually stands for, how it is employed, and what its relationship is with AI. Deep learning is a fascinating topic and is used for a multitude of applications from unders...
1. LSTM模型 输入参数理解 (Long Short-Term Memory) lstm是RNN模型的一种变种模式,增加了输入门,遗忘门,输出门。 LSTM也是在时间序列预测中的常用模型。 小白我也是从这个模型入门来开始机器学习的坑。 LSTM的基本概念与各个门的解释已经有博文写的非常详细:推荐博文:【译】理解LSTM(通俗易懂版) ...
we’ll look at the very popular LSTM, or long short-term memory unit, and the more modern and efficient GRU, or gated recurrent unit, which has been proven to yield comparable performance. We’ll apply these to some more practical problems, such as learning a language model from Wikipedia...

There are also options within RNNs. For example, the long short-term memory (LSTM) network is superior to simple RNNs by learning and acting on longer-term dependencies. However, RNNs tend to run into two basic problems, known as exploding gradients and vanishing gradients. These issues are...
