    <rdf:Description rdf:about="&cpannotationschema;scenarios">
        <cpannotationschema:scenarios>Consider a scenario in machine learning (ML) domain. 
        The scenario deals with a machine learning task realization and it is based on an example derived from the OpenML portal (http://www.openml.org). 
There is an ML Task :task29 which is a supervised classification task defined on the dataset :credit-a.
This task is achieved by the Execution :run100241 which executes the Implementation :wekaLogistic of the Algorithm :logisticRegression which
this execution realizes.
The Implementation :wekaLogistic has five hyperparameters (Parameter): :wekaLogisticC, :wekaLogisticDoNotCheckCapabilities, :wekaLogisticM, :wekaLogisticOutputDebugInfo, :wekaLogisticR. The values of two of these hyperparameters are set. The hyperparameter :wekaLogisticM has value set to -1 (expressed via the ParameterSetting :wekaLogisticMSetting29), and the hyperparameter :wekaLogisticR that has its value set to &quot;1.0E-8&quot;^^xsd:float (expressed via the ParameterSetting :wekaLogisticRSetting29).
The Execution :run100241 has on Input the :credit-a dataset and the parameter settings and its Output is the ML model :wekaLogisticModel100241.</cpannotationschema:scenarios>
