经过初步调查,常用的LSTM层有Keras.layers.LSTM和Tensorflow.contrib.nn.LSTMCell及Tensorflow.nn.rnn_cell.LSTMCell ,其中后面两个的实现逻辑是一样的。这里,Keras.layers.LSTM的计算源码文件为keras/layers/recurrent.py中的LSTMCell类。Tensorflow.contrib.nn.LSTMCell和Tensorflow.nn.rnn_cell.LSTMCell的计算源码文件...

简介:本文解析了TensorFlow和Keras中的`tf.keras.layers.Bidirectional()`层,它用于实现双向RNN(如LSTM、GRU)的神经网络结构。文章详细介绍了该层的参数配置,并通过实例演示了如何构建含有双向LSTM层的模型,以及如何使用IMDB数据集进行模型训练和评估。 1 作用 ...
