堆疊 RNN cell 層
StackedRNNCells 類別
keras.layers.StackedRNNCells(cells, **kwargs)
封裝器，允許堆疊的 RNN cells 作為單一 cell 運作。
用於實作高效堆疊 RNNs。
參數
- cells：RNN cell 實例的列表。
範例
batch_size = 3
sentence_length = 5
num_features = 2
new_shape = (batch_size, sentence_length, num_features)
x = np.reshape(np.arange(30), new_shape)
rnn_cells = [keras.layers.LSTMCell(128) for _ in range(2)]
stacked_lstm = keras.layers.StackedRNNCells(rnn_cells)
lstm_layer = keras.layers.RNN(stacked_lstm)
result = lstm_layer(x)
