Start Import Labels Task Run
glue_start_import_labels_task_run | R Documentation |
Enables you to provide additional labels (examples of truth) to be used to teach the machine learning transform and improve its quality¶
Description¶
Enables you to provide additional labels (examples of truth) to be used
to teach the machine learning transform and improve its quality. This
API operation is generally used as part of the active learning workflow
that starts with the start_ml_labeling_set_generation_task_run
call
and that ultimately results in improving the quality of your machine
learning transform.
After the start_ml_labeling_set_generation_task_run
finishes, Glue
machine learning will have generated a series of questions for humans to
answer. (Answering these questions is often called 'labeling' in the
machine learning workflows). In the case of the FindMatches
transform,
these questions are of the form, “What is the correct way to group these
rows together into groups composed entirely of matching records?” After
the labeling process is finished, users upload their answers/labels with
a call to start_import_labels_task_run
. After
start_import_labels_task_run
finishes, all future runs of the machine
learning transform use the new and improved labels and perform a
higher-quality transformation.
By default, start_ml_labeling_set_generation_task_run
continually
learns from and combines all labels that you upload unless you set
Replace
to true. If you set Replace
to true,
start_import_labels_task_run
deletes and forgets all previously
uploaded labels and learns only from the exact set that you upload.
Replacing labels can be helpful if you realize that you previously
uploaded incorrect labels, and you believe that they are having a
negative effect on your transform quality.
You can check on the status of your task run by calling the
get_ml_task_run
operation.
Usage¶
Arguments¶
TransformId
[required] The unique identifier of the machine learning transform.
InputS3Path
[required] The Amazon Simple Storage Service (Amazon S3) path from where you import the labels.
ReplaceAllLabels
Indicates whether to overwrite your existing labels.
Value¶
A list with the following syntax:
