public boolean containsTargetColumnCorrelations(String key)
Output only. Correlations between
TablesDatasetMetadata.target_column_spec_id,
and other columns of the
TablesDatasetMetadataprimary_table.
Only set if the target column is set. Mapping from other column spec id to
its CorrelationStats with the target column.
This field may be stale, see the stats_update_time field for
for the timestamp at which these stats were last updated.

Parameter
Returns
public boolean equals(Object obj)
Parameter
Returns
Overrides
public TablesDatasetMetadata getDefaultInstanceForType()
Returns
public String getMlUseColumnSpecId()
column_spec_id of the primary table column which specifies a possible ML
use of the row, i.e. the column will be used to split the rows into TRAIN,
VALIDATE and TEST sets.
Required type: STRING.
This column, if set, must either have all of TRAIN
, VALIDATE
, TEST
among its values, or only have TEST
, UNASSIGNED
values. In the latter
case the rows with UNASSIGNED
value will be assigned by AutoML. Note
that if a given ml use distribution makes it impossible to create a "good"
model, that call will error describing the issue.
If both this column_spec_id and primary table's time_column_spec_id are not
set, then all rows are treated as UNASSIGNED
.
NOTE: Updates of this field will instantly affect any other users
concurrently working with the dataset.
string ml_use_column_spec_id = 4;
Returns
Type | Description |
String | The mlUseColumnSpecId.
