If this field is None, then the ``s3_output_path`` will be used
to store the ``analysis_config`` output.
label (str): Target attribute of the model required by bias metrics.
Specified as column name or index for CSV dataset or as JSONPath for JSONLines.
*Required parameter* except for when the input dataset does not contain the label.
features (List[str]): JSONPath for locating the feature columns for bias metrics if the
dataset format is JSONLines.
dataset_type (str): Format of the dataset. Valid values are ``"text/csv"`` for CSV,

``"application/x-parquet"`` for Parquet.
s3_compression_type (str): Valid options are "None" or ``"Gzip"``.
joinsource (str or int): The name or index of the column in the dataset that
acts as an identifier column (for instance, while performing a join).
This column is only used as an identifier, and not used for any other computations.
This is an optional field in all cases except:
* The dataset contains more than one file and `save_local_shap_values`
is set to true in :class:`~sagemaker.clarify.ShapConfig`, and/or
* When the dataset and/or facet dataset and/or predicted label dataset
are in separate files.
facet_dataset_uri (str): Dataset S3 prefix/object URI that contains facet attribute(s),
used for bias analysis on datasets without facets.
* If the dataset and the facet dataset are one single file each, then
the original dataset and facet dataset must have the same number of rows.
* If the dataset and facet dataset are in multiple files (either one), then
an index column, ``joinsource``, is required to join the two datasets.
Clarify will not use the ``joinsource`` column and columns present in the facet
dataset when calling model inference APIs.
facet_headers (list[str]): List of column names in the facet dataset.
predicted_label_dataset_uri (str): Dataset S3 prefix/object URI with predicted labels,
which are used directly for analysis instead of making model inference API calls.
* If the dataset and the predicted label dataset are one single file each, then the
original dataset and predicted label dataset must have the same number of rows.
* If the dataset and predicted label dataset are in multiple files (either one),
then an index column, ``joinsource``, is required to join the two datasets.
predicted_label_headers (list[str]): List of column names in the predicted label dataset

These heat maps highlight the image's features according
to how much they contribute to the CV model prediction.
``"IMAGE_CLASSIFICATION"`` and ``"OBJECT_DETECTION"`` are the two supported CV use cases.
Args:
model_type (str): Specifies the type of CV model and use case. Accepted options:
``"IMAGE_CLASSIFICATION"`` or ``"OBJECT_DETECTION"``.
num_segments (None or int): Approximate number of segments to generate when running
SKLearn's `SLIC method <https://scikit-image.org/docs/dev/api/skimage.segmentation.html?highlight=slic#skimage.segmentation.slic>`_
for image segmentation to generate features/superpixels.
The default is None. When set to None, runs SLIC with 20 segments.
feature_extraction_method (None or str): method used for extracting features from the
image (ex: "segmentation"). Default is ``"segmentation"``.
segment_compactness (None or float): Balances color proximity and space proximity.
Higher values give more weight to space proximity, making superpixel
shapes more square/cubic. We recommend exploring possible values on a log
scale, e.g., 0.01, 0.1, 1, 10, 100, before refining around a chosen value.
The default is None. When set to None, runs with the default value of ``5``.
max_objects (None or int): Maximum number of objects displayed when running SHAP
with an ``"OBJECT_DETECTION"`` model. The Object detection algorithm may detect
more than the ``max_objects`` number of objects in a single image.
In that case, the algorithm displays the top ``max_objects`` number of objects
according to confidence score. Default value is None. In the ``"OBJECT_DETECTION"``
case, passing in None leads to a default value of ``3``.
iou_threshold (None or float): Minimum intersection over union for the object
bounding box to consider its confidence score for computing SHAP values,
in the range ``[0.0, 1.0]``. Used only for the ``"OBJECT_DETECTION"`` case,
where passing in None sets the default value of ``0.5``.
context (None or float): The portion of the image outside the bounding box used
in SHAP analysis, in the range ``[0.0, 1.0]``. If set to ``1.0``, the whole image
is considered; if set to ``0.0`` only the image inside bounding box is considered.
