下面使用tf.contrib.rnn.BasicLSTMCell分别创建forward和backward的LSTM单元,它们的隐藏节点数都设为n_hidden,而forget_bias都设为1.然后直接将正向的lstm_fw_cell和反向的lstm_bw_cell传入Bi-RNN界都tf.nn.bidirectional_rnn中,生成双向LSTM,并传入x作为输入。最后对双向LSTM的输出结果outputs做一个矩阵乘法并加上偏...

I want to implement a unidirectional and a bidirectional LSTM in tensorflow keras wrapper with the same amount of units. As an example I implement the unidirectional LSTM with 256 units, and the bidirectional LSTM with 128 units (which as I understand gives me 128 for each...
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 ...
