'Returns the input vector for the given position in the sequence pair.
Returns the vector formed by concatenating the input vector for the control
sequence and the input vector for the target sequence.
Args:
control_events: A list-like sequence of control events.
target_events: A list-like sequence of target events.
position: An integer event position in the event sequences. When
predicting the target label at position `i + 1`, the input vector is
the concatenation of the control input vector at position `i + 1` and
the target input vector at position `i`.
Returns:
An input vector, a list of floats.'

def events_to_input(self, control_events, target_events, position):

    return (self._control_encoder_decoder.events_to_input(control_events, (position + 1)) + self._target_encoder_decoder.events_to_input(target_events, position))
