join(right, on=None, time_stamps=None, relationship='many-to-many', memory=None, horizon=None, lagged_targets=False, upper_time_stamp=None)¶
Joins another to placeholder to this placeholder.
- right (
The placeholder you would like to join.
- on (None, string, Tuple[str] or List[Union[str, Tuple[str]]]):
The join keys to use. If none is passed, then everything will be joined to everything else.
- time_stamps (string or Tuple[str]):
The time stamps used to limit the join.
- relationship (str):
The relationship between the two tables. Must be from
- memory (float):
The difference between the time stamps until data is ‘forgotten’. Limiting your joins using memory can significantly speed up training time. Also refer to
- horizon (float):
The prediction horizon to apply to this join. Also refer to
- lagged_targets (bool):
Whether you want to allow lagged targets. If this is set to True, you must also pass a positive, non-zero horizon.
- upper_time_stamp (str):
Name of a time stamp in right that serves as an upper limit on the join.
