First, define a placeholder for feeding in the input (sample_inputs), then similar to the training stage, you define state variables for prediction (sample_c and sample_h). Finally you calculate the prediction with the tf.nn.dynamic_rnn function and then sending the output through the ...
本文分为四个部分,第一部分简要介绍LSTM的应用现状;第二部分介绍LSTM的发展历史,并引出了受众多学者关注的LSTM变体——门控递归单元(GRU);第三部分介绍LSTM的基本结构,由基本循环神经网络结构引出LSTM的具体结构。第四部分,应用Keras框架提供的API,比较和分析简单循环神经网络(SRN)、LSTM和GRU在手写数字mnist数据集上...
