Then later,LSTM (long short term memory) was inventedto solve this issue by explicitly introducing a memory unit, called the cell into the network. This is the diagram of a LSTM building block. 初看起来非常复杂。让我们忽略中间部分,只看单元的输入和输出。网络有三个输入,XtXt是当前的输入;ht...
In the above diagram, a chunk of neural network, \( A ), looks at some input \( xt ) and outputs a value \( ht ). A loop allows information to be passed from one step of the network to the next. These loops make recurrent neural networks seem kind of mysterious. However, if yo...

最终,我们需要处理我们当前diagram的输出是什么了。这个输出取决于我们当前的CellState(注意,这时候CellState已经在上一步被更新过了),只不过我们需要过滤掉其中的部分信息。首先,我们通过一个Sigmoid层来决定CellState的哪些部分是需要输出的。然后,我们将新的CellState通过一个tanh函数(将CellState的各部分指规则化到-...

LSTM的key是cell state C_t ,就是流经整个diagram的顶部的水平线,cell state像一个传送带,贯穿整个chain,只有一些linear interaction,要让信息流过不作修改是非常容易的。 LSTM能够删除或者修改cell state的信息,由gate来进行调控。Gate是一种让信息选择性通过的方式,由sigmoid 神经元层和pointwise multiplication操作...
