GRU is a popular variant of LSTM which replaces the forget gate and theinput gate with only one update gate GRU achieves the similar performance in multiple tasks with less computation LSTM 通过门控机制使循环神经网络不仅能记忆过去的信息,同时还能选择性地忘记一些不重要的信息而对长期语境等关系进行...
循环神经网络,LSTM,GRU RNN是一类用于处理序列数据的神经网络 序列数据:时间学列数据是指在不同时间点上收集到的数据,这类数据反映了某一事物、现象等随时间的变化状态或程度。 基础的神经网络只在层与层之间建立了权连接,RNN最大的不同之处就是在层之间的神经元之间也建立的权连接。 上图是一个标准的RNN结构...

As mentioned above, GRU is an improved version of the standard recurrent neural network, and its main idea is to make a good understanding between words, as well as it makes a much better capturing of long-range connections, in other words, it helps a lot with thevanishing gradient problem...
LSTM is short for Long Short-term memory。主要的作用是解决Naive RNN的训练过程中梯度消失的问题。它引入了一个cell state,这个cell state的改变比hidden state的改变更慢,因为cell state是在原本的cell state的基础上选择性更加内容,而hidden state的是直接全部更新替换。
is a Bernoulli random variable which is 0 with probability dropout. So essentially given a sequence, each time point should be passed through all the layers for each loop, like this implementationMeanwhile the LSTM code implementation is:...
Recurrent Neural Network (RNN) models, such as Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU), which excel at handling sequence prediction problems, have been employed by researchers to establish ROP prediction models12,13,14. Ji et al.13 discovered that LSTM performs the best ...
There is a current input xt and a hidden state ht−1 passed down by the previous node, which contains information about the previous node. Combined xt with ht−1, GRU will get the output ht of the current hidden node. Compared with the gate of LSTM, GRU has only two gated units,...

If you are new to Torch/Lua/Neural Nets, it might be helpful to know that this code is really just a slightly more fancy version of this 100-line gist that I wrote in Python/numpy. The code in this repo additionally: allows for multiple layers, uses an LSTM instead of a vanilla RNN...
