+Configuration
+=============
+
+Thetis needs a YAML configuration file that specifies several aspects, e.g., the task, available classes, requested
+evaluation aspects, etc. `Download an exemplary configuration file <https://efs-techhub.com/efs-portfolio/loesungen/thetis>`__ or copy/paste the
+following configuration file. An explanation for each configuration aspect can be found below.
+
+
+Example Configuration File
+--------------------------
+
+An exemplary YAML configuration for Thetis must have the following form:
+
+.. code-block:: yaml
+
+   # meta data of model predictions and data set
+   meta:

+     distinct_classes: ["no person", "person"]
+
+     # In binary classification (when 'distinct_classes' has length of 2), you must specify a positive label out of
+     # the list of available classes. This is important since you only give a single "confidence" for each prediction,
+     # targeting the probability of the positive class. May only be specified for binary classification.
+     binary_positive_label: "person"

+     # Bounding-box format. Can be one of: "xyxy" (xmin, ymin, xmax, ymax), "xywh" (xmin, ymin, width, height),

+General Application Settings

+     - Description
+   * - :code:`task`
+     - string
+     - Selection of the examination task. Can be one of: "classification" (binary/multi-class classification), "detection" (image-based object detection).
+   * - :code:`language`
+     - string
+     - Language of the final evaluation report. Can be one of: "en" (US English), "de" (German).
+   * - :code:`task_settings/distinct_classes`
+     - list of int or string
+     - List of distinct classes that can occur within the data set. Only to be provided in case of Classification or Detection
+   * - :code:`task_settings/binary_positive_label`
+     - int or string
+     - In binary classification (when 'distinct_classes' has length of 2), you must specify a positive label out of
+       the list of available classes. This is important since you only give a single "confidence" for each prediction,
+       targeting the probability of the positive class.
+   * - :code:`task_settings/detection_bbox_format`
+     - string
+     - Bounding-box format of the provided boxes in object detection mode. Can be one of: "xyxy" (xmin, ymin, xmax, ymax),
+       "xywh" (xmin, ymin, width, height), or "cxcywh" (center x, center y, width, height).
+   * - :code:`task_settings/detection_bbox_ious`
+     - list of float
+     - List with IoU scores (in [0, 1] interval) used for object detection evaluation.
+       Note: the IoU score "0.5" is always active for the evaluation. You can specify more IoU scores if you want.
+   * - :code:`task_settings/detection_bbox_matching`
+     - string
+     - String with bounding box matching strategy within object detection evalulation. The strategy of matching the
+       predicted bounding boxes with the ground truth ones must either be "exclusive" with
+       exclusive bounding box matching where each prediction and each ground truth are assigned
+       to a single counter-part, or "max" with maximum/non-exclusive bounding box matching where each ground truth object
+       may have multiple predictions assigned to it. Default is "exclusive".
+   * - :code:`task_settings/detection_bbox_probabilistic`
+     - boolean
+     - Currently not used.
+   * - :code:`task_settings/detection_confidence_thr`
+     - float
+     - In detection mode, it is possible to set a confidence threshold (in [0, 1] interval) to discard blurry predictions with low confidence.
+  * - :code:`task_settings/detection_bbox_clipping`
+     - int
+     - In detection mode, it is possible to specify tolerance zone outside the image in case of boxes that are out of image bounds.
+       This can be ommitted, in which case no clipping is applied and an error is raised if a box is out of image bounds.
+       Alternatively, it can be set to relative(relative to image width and height)% ([0-100]%) or absolute values in px ([int]px). 
+       These specify the dimensions outside the image, such that if any boxes extend into this tolerance zone, they will get clipped to the image dimensions. 
+       If boxes exceed these tolerance zones no clipping will be applied, an error will be raised instead.

+   :header-rows: 1
+
+   * - Key/Specifier
+     - Dtype
+     - Description
+   * - :code:`uncertainty/examine`
+     - boolean
+     - Enables/disables the uncertainty evaluation (uncertainty calibration, e.g., computation of the Expected Calibration Error (ECE)) for the final rating & reporting.
+   * - :code:`uncertainty/ece_bins`
+     - int
+     - Number of bins used for the computation of the Expected Calibration Error (ECE), Maximum Calibration Error (MCE),
+       and the respective reliability diagrams. The default value is 20.
+   * - :code:`uncertainty/ece_sample_threshold`
+     - int
+     - Sample threshold used for the computation of the ECE, MCE, D-ECE, and the respective reliability diagrams to discard
+       bins with an amount of samples below this threshold. Discarding bins with only a small amount of samples is
+       recommended to stabilize the ECE/MCE computations. The default value is 10.
+   * - :code:`uncertainty/dece_bins`
+     - int
+     - Number of bins used for the computation of the Decetion Expected Calibration Error (D-ECE) (object detection only)

+       evaluation of object detection tasks. The default value is 5.

+     - boolean
+     - Enables/disables the AI fairness evaluation for the final rating & reporting.
+   * - :code:`fairness/sensitive_attributes/<label name>`
+     - optional string or list of int/string
+     - Specify one or multiple sensitive attributes (e.g., gender or age) that are used for fairness evaluation.
+       The value of this entry is a list of target classes (given by "distinct_classes" parameter) for which the
+       sensitive attribute is valid. For example, if "distinct_classes" specifies labels "person" and "car", a
+       sensitive attribute for "gender" might only be valid for target label "person". If the attribute is valid for
+       all specified target labels, you can also leave the value empty or pass "all".
