循环神经网络(Recurrent Neural Network, RNN)是一类具有内部环状连接的人工神经网络,用于处理序列数据。其最大特点是网络中存在着环,使得信息能在网络中进行循环,实现对序列信息的存储和处理。 网络结构 RNN的基本结构如下: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 # 一个简单的RNN结构示例classSimpleRNN...
由于GPU版是直接调用NVIDIA cuDNN的RNN API,这里咱就略去不表,CPU版最开始使用Python实现,自v1.0.0之后改为C++,为了不让语言成为理解RNN的障碍,所以本文以最后一个Python实现版本 v0.4.1为例讲述RNN模型。 RNN,更准确的说,torch.nn.RNN,实现的是Jeffrey Elman在1990年提出的simple recurrent neural network (SRN...
