Bidirectional wrapper for RNNs.

    Bidirectional wrapper for RNNs.

    bidirectional(
      object,
      layer,
      merge_mode = "concat",
      input_shape = NULL,
      batch_input_shape = NULL,
      batch_size = NULL,
      dtype = NULL,
      name = NULL,
      trainable = NULL,
      weights = NULL
    )

    Arguments

    object

    Model or layer object

    layer

    Recurrent instance.

    merge_mode

    Mode by which outputs of the forward and backward RNNs will be combined. One of 'sum', 'mul', 'concat', 'ave', NULL. If NULL, the outputs will not be combined, they will be returned as a list.

    input_shape

    Dimensionality of the input (integer) not including the samples axis. This argument is required when using this layer as the first layer in a model.

    batch_input_shape

    Shapes, including the batch size. For instance, batch_input_shape=c(10, 32) indicates that the expected input will be batches of 10 32-dimensional vectors. batch_input_shape=list(NULL, 32) indicates batches of an arbitrary number of 32-dimensional vectors.

    batch_size

    Fixed batch size for layer

    dtype

    The data type expected by the input, as a string (float32, float64, int32...)

    name

    An optional name string for the layer. Should be unique in a model (do not reuse the same name twice). It will be autogenerated if it isn't provided.

    trainable

    Whether the layer weights will be updated during training.

    weights

    Initial weights for layer.
