Changeset 8679 for trunk/sources/HeuristicLab.Problems.DataAnalysis/3.4/Implementation/Classification

Timestamp:

Message:

#1902 changed DiscriminantFunctionClassificationModel and DiscriminantFunctionClassificationSolution to non-abstract. Classification based on GPR uses these classes to create a classification solution from a GaussianProcessRegressionModel.
Also added view classes for DiscriminantFunctionClassificationModel

Location:

Files:

• DiscriminantFunctionClassificationModel.cs (modified) (3 diffs)
• DiscriminantFunctionClassificationSolution.cs (modified) (3 diffs)
