Used to implement efficient stacked RNNs.

Usage

rnn_cells_stack(cells, ...)

Arguments

cells

List of RNN cell instances.

...

Unnamed arguments are treated as additional cells. Named arguments are passed on to the underlying layer.

Value

A Layer instance, which is intended to be used with layer_rnn().

Examples

batch_size <- 3
sentence_length <- 5
num_features <- 2
new_shape <- c(batch_size, sentence_length, num_features)
x <- array(1:30, dim = new_shape)

rnn_cells <- lapply(1:2, function(x) rnn_cell_lstm(units = 128))
stacked_lstm <- rnn_cells_stack(rnn_cells)
lstm_layer <- layer_rnn(cell = stacked_lstm)

result <- lstm_layer(x)
str(result)

## <tf.Tensor: shape=(3, 128), dtype=float32, numpy=…>
