Welcome to Data Processing Compendium – Workflows for Knowledge Exploitation in the Process Industries!
=======================================================================================================

The *Data Processing Compendium* is a catalogue of methods for data processing, so far with a focus on data pre-processing. The compendium is a key result of the AiF research project *Knowledge based pre-processing of process data (IGF-Vorhaben Nr. 16901 N)*. The project has been conducted by `AixCAPE® e.V. <http://www.aixcape.org>`_

Support and feedback by 12 :ref:`industrial partners <project-partners>` from Belgium, France, and Germany is greatly acknowledged.


Overview
========

Algorithms
----------

Algorithms such as :doc:`/Algorithms/BackwardDifference/index` and :doc:`/Algorithms/HoltWintersDoubleExponentialSmoothing/index` are the foundation to solve many data processing tasks. Algorithms can be accessed in three different ways:

.. toctree::
   :maxdepth: 1
   :hidden:

   Algorithms/index
   WorkProcessClassifiers/index
   Tools/index

- :doc:`/Algorithms/index`: An alphabetical list of algorithms.

- :doc:`/WorkProcessClassifiers/index`: Algorithms classified by basic properties, for example  :doc:`/WorkProcessClassifiers/OneDimensionalAlgorithm/index` and :doc:`/WorkProcessClassifiers/MultiDimensionalAlgorithm/index`.

- :doc:`/Tools/index`: Algorithms grouped by implementing tools, for example :doc:`/Tools/ExcelTool/index` and :doc:`/Tools/MatlabTool/index`.

Single Steps
------------

Single steps provide a task-oriented view on data processing. They are arranged in a hierarchy of tasks, for example :doc:`/DataPreprocessing/index` → :doc:`/DataPreprocessing/DataCleaning/index` → :doc:`/DataPreprocessing/DataCleaning/HandlingImproperValues/index` → :doc:`/DataPreprocessing/DataCleaning/HandlingImproperValues/ReconstructingImproperValues/index`. The lowest level in the hierarchy contains the actual single steps, typically identified by an algorithm, for example :doc:`/DataPreprocessing/DataCleaning/HandlingImproperValues/ReconstructingImproperValues/ReconstructingImproperValuesWithLocalCenteredMovingMedian/index`.

.. toctree::
   :maxdepth: 1
   :hidden:

   DataPreprocessing/index
   SingleStepClassifiers/index

- :doc:`/DataPreprocessing/index`: Hierarchy of single steps.

- :doc:`/SingleStepClassifiers/index`: Single steps classified by basic properties, for example  :doc:`/SingleStepClassifiers/OutlierResistantStep/index`.

Reference Processes
-------------------

Reference processes are best practice procedures for more complex tasks from literature or provided by our project partners. 

.. toctree::
   :maxdepth: 1
   :hidden:

   ReferenceProcesses/index
   
- :doc:`/ReferenceProcesses/index`: List of reference processes.
