call(inputs)

Compute the output of the Seasonality Block.

Parameters:

inputs (tf.Tensor) – A tensor of shape (batch_size, train_sequence_length, input_size)

Returns:

A tuple of two tensors: - backcast: Shape (batch_size, train_sequence_length, output_size) - forecast: Shape (batch_size, predict_sequence_length, output_size)

Return type:

Tuple[tf.Tensor, tf.Tensor]

get_config()

Returns the config of the object.

An object config is a Python dictionary (serializable) containing the information needed to re-instantiate it.
