docstr: Needs to be implemented by subclass.
  
  Parameters
  ----------
      t : torch.Tensor float
          normalized time, dim: (batch, n_forecasts)
      meta: dict
          Metadata about the all the samples of the model input batch. Contains the following:
              * ``df_name`` (list, str), time series ID corresponding to each sample of the input batch.
  Returns
  -------
      torch.Tensor
          Component forecast, same dimensions as input t
