Subclasses implement apply() for channel-first arrays.
-
abstractmethod apply(data: ndarray) → ndarray[source]

- Parameters:
- datandarray, shape (n_channels, n_times) or (n_channels, n_times, n_epochs)
Input data.
- Returns:
- biasedndarray, same shape as input
Biased data with signal of interest emphasized.
