+   
+      BayesValidRox gives options to create interfaces for a variety of models with the class :any:`bayesvalidrox.pylink.pylink.PyLinkForwardModel`.
+	  
+	  Its main function is to run the model on given samples and to read in and contain MC references and observations.
+	  
+	  Models can be defined via python functions, shell commands or as general executables.
+	  This allows for the use of BayesValidRox with a broad range of models and easy extension to models that are defined with e.g. UM-Bridge.

+         :alt: UML diagram for the bayesvalidrox class :any:`bayesvalidrox.pylink.pylink.PyLinkForwardModel`.
+   
+Example
+=======
+For this example we use a very simple model that maps the uncertain parameter :math:`X` from the example in :any:`input_description` to two outputs, the original value and its square.
+We define this model as a function ``model`` in a new file ``model.py``.
+This function takes a single realization of the uncertain parameter as a 2-dimensional ``np.array`` and returns a dictionary of model results.
+Here we use the key ``A`` for the sample values and ``B`` for their squares.
+Under the key ``x_values`` a list should be given that is of the same length as each output of the model for a single input.
+The values in this list can denote e.g. timesteps and are used in postprocessing as labels of the x-axis.
+
+>>> def model(sample):
+>>>     square = sample*sample
+>>>     outputs = {'A': sample, 'B': square, 'x_values': [0]}
+>>>     return outputs
+
+In the main python file we can create an object of :any:`bayesvalidrox.pylink.pylink.PyLinkForwardModel` that links to this model.
+
+>>> from bayesvalidrox import PyLinkForwardModel
+
+We create an object of this class and set the ``link_type`` as 'Function' to indicate that this is a function in a python file.
+``py_file`` should be set to the filename of the model and ``name`` to the name of the function.
+Lastly we list the keys of the outputs that we are interested in.
+
+>>> Model = PyLinkForwardModel()
+>>> Model.link_type = 'Function'
+>>> Model.py_file = 'model'
+>>> Model.name = 'model'
+>>> Model.Output.names = ['A', 'B']
+
+With this we have completed an interface to our model.
+We can now evaluate this model on the samples created in the input example.
+
+>>> output, samples = Model.run_model_parallel(samples)
+
+Other types of model links can be found in :any:`examples`, e.g. :any:`beam` uses a shell command and parser.

+Postprocessing
+**************
+.. container:: twocol
+
+   .. container:: leftside
+   
+         Postprocessing refers to evaluations and checks performed on a model to get an understanding of its properties and estimate its quality.
+         The BayesValidRox class :any:`bayesvalidrox.post_processing.post_processing.PostProcessing` includes functions that are applicable to all types of surrogate model.
+		 
+		 * ``valid_metamodel``: visualizing some metamodel runs against the corresponding model runs
+		 * ``check_accuracy``: computing the RMSE error of the surrogate model
+		 
+   .. container:: rightside
+

+         :width: 300
+         :alt: UML diagram for the classes and functions used in active learning in BayesValidRox.
+		
+Postprocessing methods that are specific to a type of surrogate or training include
+
+* ``plot_moments``: visualizing the moments of a polynomial chaos expansion (PCE, aPCE)
+* ``sobol_indices``: calculating the Sobol' and Total Sobol' indices (PCE, aPCE)
+* ``plot_seq_design_diagnostics``: visualizing diagnostics that were evaluated during sequential training (surrogate trained with ``train_sequential``)
+
+		 
+Example
+=======
+We want to compare out trained surrogate from :any:`al_description` against its original model.
+
+>>> from bayesvalidrox import PostProcessing
+
+The postprocessing object expects the full engine. This allows it to perform both sampling, running the model and running the surrogate model.
+
+>>> PostProc = PostProcessing(Engine_)
+
+To gain an understanding of the approximation quality we use both ``valid_metamodel`` and ``check_accuracy``.
+
+>>> PostProc.valid_metamodel(n_samples=1)
+>>> PostProc.check_accuracy(n_samples=10)
+
+The visual comparison of model and metamodel results is saved in the folder ``Outputs_PostProcessing_calib``, while the accuracy check is given as console output.

 Training surrogate models
-*************************
\ No newline at end of file
+*************************
+Surrogate models, also called metamodels, are models that are built on evaluations of full models with the goal to capture the full behaviour, but reduce the cost of evaluations.
+
+In BayesValidRox two types of surrogate model are available, polynomial chaos expansion and Gaussian processes.
+The Polynomial Chaos Expansion (PCE) and its variant the arbitrary Polynomial Chaos Expansion (aPC) build polynomials from the given distributions of uncertain inputs.
+Gaussian processes (GP) give kernel-based representations of the model results.
+
+The surrogate models are trained on datasets :math:`\mathcal{D}=(x_i, y_i)_{i=1,\dots,M)` that consist of :math:`M` samples of the uncertain parameters and the corresponding model outputs.
+We call this dataset the training data, with training samples :math:`(x_i)_{i=1,\dots,M)`.
+
+
+MetaModel and Engine classes
+============================
+BayesValidRox creates surrogate models as objects of the class :any:`bayesvalidrox.surrogate_models.surrogate_models.MetaModel`.
+Training is performed by the class :any:`bayesvalidrox.surrogate_models.engine.Engine`.

+=================
+
+
+Training with the engine
+========================
+For training a surrogate model we use an object of class :any:`bayesvalidrox.surrogate_models.engine.Engine`.
+This needs to be given three things: the metamodel itself, the model that the metamodel should replace and the experimental design that matches the uncertain inputs for the model and metamodel.
+
+The standard method of training the surrogate is performed by the function ``train_normal()``.
+Other available training methods in BayesValidRox are presented in :any:`al_description`.
+
+For training the engine performs three main steps.
+
+1) Generating training samples from the experimental design.
+2) Evaluating the model on the training samples.
+3) Fitting the surrogate to the training dataset.
+
+Example
+=======
+We now build a surrogate model for the simple model from :any:`model_description` using the experimental design from :any:`input_description`.
+For this we need the classes :any:`bayesvalidrox.surrogate_models.surrogate_models.MetaModel` and :any:`bayesvalidrox.surrogate_models.engine.Engine`.
+
+>> from bayesvalidrox import MetaModel, Engine
+
+First we set up the surrogate model and tell it to consider the uncertain parameters defined in ``Inputs`` as its input parameters.
+
+>>> MetaMod = MetaModel(Inputs)
+
+Then we specify what type of surrogate we want and its properties.
+Here we use an aPCE with maximal polynomial degree 3 and want to use FastARD as the regression method.
+We set the value of the q-norm truncation scheme to 0.9.
+This combination will give us a sparse aPCE.
+
+>>> MetaMod.meta_model_type = 'aPCE'
+>>> MetaMod.pce_reg_method = 'FastARD'
+>>> MetaMod.pce_deg = 3
+>>> MetaMod.pce_q_norm = 0.85
+
+Before we start the actual training we need to set some training-related values for the experimental design.
+Most importantly we set the attribute ``method`` to 'normal' to indicate that no iterations are performed during the training and we set ``n_init_samples`` to our wanted number of training samples.
+
+.. warning::
+   The attribute ``method`` will be deprecated in further release.
+   
+>>> ExpDesign.method = 'normal'
+>>> ExpDesign.n_init_samples = 10
+
+Like this the experimental design will generate 10 samples according to our previously set sampling method.
+Alternatively we can set the samples that we generated in :any:`input_description` as the training samples.
+For this the sampling method should be set to 'user' and our samples given as ``X``.
+
+>>> ExpDesign.sampling_method = 'user'
+>>> ExpDesign.root_samples = samples
+
+Now we create an engine object with the model, experimental design and surrogate model.
+With the function ``start_engine`` the engine performs its preparations for training.
+
+.. warning::
+   The function start_engine will likely be deprecated in future releases.
+
+>>> Engine_ = Engine(MetaMod, Model, ExpDesign)
+>>> Engine_.start_engine()
+
+Then we train the surrogate model.
+
+>>> Engine.train_normal()
+
+We can evaluate the trained surrogate model in two ways, via the engine, or directly.
+The evaluations return the mean approximation of the surrogate and its associated standard deviation.
+Evaluation via the surrogate model can make use of the sampling in the experimental design,
+
+>>> mean, stdev = Engine_.eval_metamodel(nsamples = 10)
+
+while for direct evaluation the exact set of samples has to be given.
+
+>>> mean, stdev = Engine_.MetaModel.eval_metamodel(samples)

+<h2>Example<a class="headerlink" href="#example" title="Link to this heading">¶</a></h2>
+<p>For this example we use a very simple model that maps the uncertain parameter <span class="math notranslate nohighlight">\(X\)</span> from the example in <a class="reference internal" href="input_description.html"><span class="doc">Priors, input space and experimental design</span></a> to two outputs, the original value and its square.
+We define this model as a function <code class="docutils literal notranslate"><span class="pre">model</span></code> in a new file <code class="docutils literal notranslate"><span class="pre">model.py</span></code>.
+This function takes a single realization of the uncertain parameter as a 2-dimensional <code class="docutils literal notranslate"><span class="pre">np.array</span></code> and returns a dictionary of model results.
+Here we use the key <code class="docutils literal notranslate"><span class="pre">A</span></code> for the sample values and <code class="docutils literal notranslate"><span class="pre">B</span></code> for their squares.
+Under the key <code class="docutils literal notranslate"><span class="pre">x_values</span></code> a list should be given that is of the same length as each output of the model for a single input.
+The values in this list can denote e.g. timesteps and are used in postprocessing as labels of the x-axis.</p>

 <h1>Training surrogate models<a class="headerlink" href="#training-surrogate-models" title="Link to this heading">¶</a></h1>
+<p>Surrogate models, also called metamodels, are models that are built on evaluations of full models with the goal to capture the full behaviour, but reduce the cost of evaluations.</p>
+<p>In BayesValidRox two types of surrogate model are available, polynomial chaos expansion and Gaussian processes.
+The Polynomial Chaos Expansion (PCE) and its variant the arbitrary Polynomial Chaos Expansion (aPC) build polynomials from the given distributions of uncertain inputs.
+Gaussian processes (GP) give kernel-based representations of the model results.</p>
+<p>The surrogate models are trained on datasets <span class="math notranslate nohighlight">\(\mathcal{D}=(x_i, y_i)_{i=1,\dots,M)\)</span> that consist of <span class="math notranslate nohighlight">\(M\)</span> samples of the uncertain parameters and the corresponding model outputs.

+<p>We now build a surrogate model for the simple model from <a class="reference internal" href="model_description.html"><span class="doc">Models</span></a> using the experimental design from <a class="reference internal" href="input_description.html"><span class="doc">Priors, input space and experimental design</span></a>.
+For this we need the classes <a class="reference internal" href="_autosummary/bayesvalidrox.surrogate_models.surrogate_models.MetaModel.html#bayesvalidrox.surrogate_models.surrogate_models.MetaModel" title="bayesvalidrox.surrogate_models.surrogate_models.MetaModel"><code class="xref any py py-class docutils literal notranslate"><span class="pre">bayesvalidrox.surrogate_models.surrogate_models.MetaModel</span></code></a> and <a class="reference internal" href="_autosummary/bayesvalidrox.surrogate_models.engine.Engine.html#bayesvalidrox.surrogate_models.engine.Engine" title="bayesvalidrox.surrogate_models.engine.Engine"><code class="xref any py py-class docutils literal notranslate"><span class="pre">bayesvalidrox.surrogate_models.engine.Engine</span></code></a>.</p>
+<p>&gt;&gt; from bayesvalidrox import MetaModel, Engine</p>
+<p>First we set up the surrogate model and tell it to consider the uncertain parameters defined in <code class="docutils literal notranslate"><span class="pre">Inputs</span></code> as its input parameters.</p>

+</pre></div>
+</div>
+<p>Then we specify what type of surrogate we want and its properties.
+Here we use an aPCE with maximal polynomial degree 3 and want to use FastARD as the regression method.
+We set the value of the q-norm truncation scheme to 0.9.
+This combination will give us a sparse aPCE.</p>

+<p>Before we start the actual training we need to set some training-related values for the experimental design.
+Most importantly we set the attribute <code class="docutils literal notranslate"><span class="pre">method</span></code> to ‘normal’ to indicate that no iterations are performed during the training and we set <code class="docutils literal notranslate"><span class="pre">n_init_samples</span></code> to our wanted number of training samples.</p>

+</div>
+<p>Like this the experimental design will generate 10 samples according to our previously set sampling method.
+Alternatively we can set the samples that we generated in <a class="reference internal" href="input_description.html"><span class="doc">Priors, input space and experimental design</span></a> as the training samples.
+For this the sampling method should be set to ‘user’ and our samples given as <code class="docutils literal notranslate"><span class="pre">X</span></code>.</p>

+<p>Now we create an engine object with the model, experimental design and surrogate model.

+</div>
+<p>We can evaluate the trained surrogate model in two ways, via the engine, or directly.

+   
+      BayesValidRox gives options to create interfaces for a variety of models with the class :any:`bayesvalidrox.pylink.pylink.PyLinkForwardModel`.
+	  
+	  Its main function is to run the model on given samples and to read in and contain MC references and observations.
+	  
+	  Models can be defined via python functions, shell commands or as general executables.
+	  This allows for the use of BayesValidRox with a broad range of models and easy extension to models that are defined with e.g. UM-Bridge.

+         :alt: UML diagram for the bayesvalidrox class :any:`bayesvalidrox.pylink.pylink.PyLinkForwardModel`.
+   
+Example
+=======
+For this example we use a very simple model that maps the uncertain parameter :math:`X` from the example in :any:`input_description` to two outputs, the original value and its square.
+We define this model as a function ``model`` in a new file ``model.py``.
+This function takes a single realization of the uncertain parameter as a 2-dimensional ``np.array`` and returns a dictionary of model results.
+Here we use the key ``A`` for the sample values and ``B`` for their squares.
+Under the key ``x_values`` a list should be given that is of the same length as each output of the model for a single input.
+The values in this list can denote e.g. timesteps and are used in postprocessing as labels of the x-axis.
+
+>>> def model(sample):
+>>>     square = sample*sample
+>>>     outputs = {'A': sample, 'B': square, 'x_values': [0]}
+>>>     return outputs
+
+In the main python file we can create an object of :any:`bayesvalidrox.pylink.pylink.PyLinkForwardModel` that links to this model.
+
+>>> from bayesvalidrox import PyLinkForwardModel
+
+We create an object of this class and set the ``link_type`` as 'Function' to indicate that this is a function in a python file.
+``py_file`` should be set to the filename of the model and ``name`` to the name of the function.
+Lastly we list the keys of the outputs that we are interested in.
+
+>>> Model = PyLinkForwardModel()
+>>> Model.link_type = 'Function'
+>>> Model.py_file = 'model'
+>>> Model.name = 'model'
+>>> Model.Output.names = ['A', 'B']
+
+With this we have completed an interface to our model.
+We can now evaluate this model on the samples created in the input example.
+
+>>> output, samples = Model.run_model_parallel(samples)
+
+Other types of model links can be found in :any:`examples`, e.g. :any:`beam` uses a shell command and parser.

+Postprocessing
+**************
+.. container:: twocol

+   
+         Postprocessing refers to evaluations and checks performed on a model to get an understanding of its properties and estimate its quality.

+
+* ``plot_moments``: visualizing the moments of a polynomial chaos expansion (PCE, aPCE)
+* ``sobol_indices``: calculating the Sobol' and Total Sobol' indices (PCE, aPCE)
+* ``plot_seq_design_diagnostics``: visualizing diagnostics that were evaluated during sequential training (surrogate trained with ``train_sequential``)
+

+Example
+=======
+We want to compare out trained surrogate from :any:`al_description` against its original model.

+>>> from bayesvalidrox import PostProcessing
+
+The postprocessing object expects the full engine. This allows it to perform both sampling, running the model and running the surrogate model.
+
+>>> PostProc = PostProcessing(Engine_)
+
+To gain an understanding of the approximation quality we use both ``valid_metamodel`` and ``check_accuracy``.
+
+>>> PostProc.valid_metamodel(n_samples=1)
+>>> PostProc.check_accuracy(n_samples=10)
+
+The visual comparison of model and metamodel results is saved in the folder ``Outputs_PostProcessing_calib``, while the accuracy check is given as console output.

 Training surrogate models
-*************************
\ No newline at end of file
+*************************
+Surrogate models, also called metamodels, are models that are built on evaluations of full models with the goal to capture the full behaviour, but reduce the cost of evaluations.
+
+In BayesValidRox two types of surrogate model are available, polynomial chaos expansion and Gaussian processes.
+The Polynomial Chaos Expansion (PCE) and its variant the arbitrary Polynomial Chaos Expansion (aPC) build polynomials from the given distributions of uncertain inputs.
+Gaussian processes (GP) give kernel-based representations of the model results.
+
+The surrogate models are trained on datasets :math:`\mathcal{D}=(x_i, y_i)_{i=1,\dots,M)` that consist of :math:`M` samples of the uncertain parameters and the corresponding model outputs.
+We call this dataset the training data, with training samples :math:`(x_i)_{i=1,\dots,M)`.
+
+
+MetaModel and Engine classes
+============================
+BayesValidRox creates surrogate models as objects of the class :any:`bayesvalidrox.surrogate_models.surrogate_models.MetaModel`.
+Training is performed by the class :any:`bayesvalidrox.surrogate_models.engine.Engine`.
+
+.. image:: ../diagrams/metamod_training_reduced.png
+   :width: 800
+   :alt: UML diagram for metamodel-related classes in bayesvalidrox
+   
+MetaModel options
+=================
+
+
+Training with the engine
+========================
+For training a surrogate model we use an object of class :any:`bayesvalidrox.surrogate_models.engine.Engine`.
+This needs to be given three things: the metamodel itself, the model that the metamodel should replace and the experimental design that matches the uncertain inputs for the model and metamodel.
+
+The standard method of training the surrogate is performed by the function ``train_normal()``.
+Other available training methods in BayesValidRox are presented in :any:`al_description`.
+
+For training the engine performs three main steps.
+
+1) Generating training samples from the experimental design.
+2) Evaluating the model on the training samples.
+3) Fitting the surrogate to the training dataset.
+
+Example
+=======
+We now build a surrogate model for the simple model from :any:`model_description` using the experimental design from :any:`input_description`.
+For this we need the classes :any:`bayesvalidrox.surrogate_models.surrogate_models.MetaModel` and :any:`bayesvalidrox.surrogate_models.engine.Engine`.
+
+>> from bayesvalidrox import MetaModel, Engine
+
+First we set up the surrogate model and tell it to consider the uncertain parameters defined in ``Inputs`` as its input parameters.
+
+>>> MetaMod = MetaModel(Inputs)
+
+Then we specify what type of surrogate we want and its properties.
+Here we use an aPCE with maximal polynomial degree 3 and want to use FastARD as the regression method.
+We set the value of the q-norm truncation scheme to 0.9.
+This combination will give us a sparse aPCE.
+
+>>> MetaMod.meta_model_type = 'aPCE'
+>>> MetaMod.pce_reg_method = 'FastARD'
+>>> MetaMod.pce_deg = 3
+>>> MetaMod.pce_q_norm = 0.85
+
+Before we start the actual training we need to set some training-related values for the experimental design.
+Most importantly we set the attribute ``method`` to 'normal' to indicate that no iterations are performed during the training and we set ``n_init_samples`` to our wanted number of training samples.
+
+.. warning::
+   The attribute ``method`` will be deprecated in further release.
+   
+>>> ExpDesign.method = 'normal'
+>>> ExpDesign.n_init_samples = 10
+
+Like this the experimental design will generate 10 samples according to our previously set sampling method.
+Alternatively we can set the samples that we generated in :any:`input_description` as the training samples.
+For this the sampling method should be set to 'user' and our samples given as ``X``.
+
+>>> ExpDesign.sampling_method = 'user'
+>>> ExpDesign.root_samples = samples
+
+Now we create an engine object with the model, experimental design and surrogate model.
+With the function ``start_engine`` the engine performs its preparations for training.
+
+.. warning::
+   The function start_engine will likely be deprecated in future releases.
+
+>>> Engine_ = Engine(MetaMod, Model, ExpDesign)
+>>> Engine_.start_engine()
+
+Then we train the surrogate model.
+
+>>> Engine.train_normal()
+
+We can evaluate the trained surrogate model in two ways, via the engine, or directly.
+The evaluations return the mean approximation of the surrogate and its associated standard deviation.
+Evaluation via the surrogate model can make use of the sampling in the experimental design,
+
+>>> mean, stdev = Engine_.eval_metamodel(nsamples = 10)
+
+while for direct evaluation the exact set of samples has to be given.
+
+>>> mean, stdev = Engine_.MetaModel.eval_metamodel(samples)
