Model Comparison for Classification #1998

Closed HeuristicLab-Trac-Bot closed 8 years ago

HeuristicLab-Trac-Bot commented 11 years ago

Issue migrated from trac ticket # 1998

milestone: HeuristicLab 3.3.13 | component: Algorithms.DataAnalysis | priority: high | resolution: done

2012-12-17 17:09:17: @t-h-e created the issue

Similar to Regression, it shall be possible to easily create simple models for classification, which a classification model has to exceed to be accepted as good model.

0R, 1R and LDA classifiers will be created to compare them to the hopefully better classification model.

r9073: branch project Problems.DataAnalysis

r9074:

  • added ZeroR and OneR classifiers
  • added ConstantClassificationModel/-Solution and OneRClassificationModel/-Solution

A view to display the OneRClassificationModel has to be added.

r9135:

  • OneR now handles missing values separately
  • adapted OneRClassificationModelView to show the class of missing values
  • with a double-click on the row header in ClassificationSolutionComparisonView the selected solution opens in a new view
  • put a try catch block around linear discriminant analysis solution (it is only shown, if it doesn't throw an exception)

ZeroR may not be a good model in the ClassificationSolutionComparisonView, because MatthewsCorrelationCoefficientCalculator will always calculate NaN and F1 score will also be NaN if the negative class is chosen by ZeroR.

Discussed in architects meeting, should be integrated into the trunk.

Please review r10560, r10568 to r10570. All other changesets have already been reviewed.

For comparison reasons I left the original version of the OneR algorithm untouched.

Reviewed r10560 changes are OK:

Made a more detailed review of the source code. Notes from the overall source code review:

  • Adapt to work with current trunk version (export button).
  • Exception occurs when running a linear discriminant analysis model (works for the trunk) cannot reproduce
  • Move OneR and ZeroR out of the Algorithms.DataAnalysis.Linear folder. done
  • OneR and ZeroR should not be available in the "New Item" dialog. done
  • ExecutionTime for OneR should not be produced as a result. I guess this is ok.
  • The file OneRTest.cs can be deleted? No, the OneRTest.cs file is the new implementation by mkommend. The file OneR.cs should be deleted

r13091: minor changes while reviewing

Reviewed changes in

  • HeuristicLab.Problems.DataAnalysis (online calculators of F1-score and Matthews correlation have been added)
  • HeuristicLab.Algorithms.DataAnalysis (ZeroR and OneR algorithms have been added)
  • HeuristicLab.Problems.DataAnalysis.Views (only ClassificationSolutionComparisonView has been added)
  • HeuristicLab.Algorithms.DataAnalysis.Views (only the OneRClassificationModelView has been added)

TODO:

  • don't calculate F1 score for multi-class problems
  • terminate branch
  • more detailed review of online calculators and algorithms
  • add F1 score and Matthew's correlation to classification results collection
  • mark ConstantRegressionModel obsolete and create new class: ConstantModel
