#2904 closed enhancement (done)

Create new CalculateImpacts method for a set of variables

Reported by: fholzing Owned by: mkommend
Priority: medium Milestone: HeuristicLab 3.3.16
Component: Algorithms.DataAnalysis Version: trunk
Keywords: Cc:

Description

Currently the calculation of the VariableImpacts isn't possible for a single variable or a chosen set of variables. Two new methods like the current RegressionSolutionVariableImpactsCalculator.CalculateImpacts and ClassificationSolutionVariableImpactsCalculator.CalculateImpacts should be created which take an additional set of variables as an input.

comment:10 Changed 6 years ago by fholzing

r15831: Refactored RegressionSolutionVariableImpactsCalculator. We don't depend on the solution anymore. The impact can be calculated for a single variable. The calculator can be chosen.

Important Points:
I guess the same refactoring should be also applied to Classifications.
There may be a better alternative than the additional method in the Interface IOnlineCalculator.
Some OnlineCalculators aren't in the branch, so attention is required as we merge the branch.
Additional UnitTest are preferred.
The UI doesn't support the new functionality (Maybe in an additional ticket later on).

Review comments

  • Adhere to the coding styles and fix the parentheses in the impact calculator
  • Factor replacement method cannot be set in a property
  • Program as threadsafe as possible -> No static properties that can be modified (Calculator)
  • Line 163 use Count() directly instead of .Where().Count()
  • Use self-explaining parameter names and not IDataset problemData
  • EvaluateModelWithReplacedVariable should be replace to GetReplacedValues or something similar that describes its purpose and not call EvaluateModelWithReplacedVariable .
  • EvaluateModelWithReplacedVariable should have a better ordering of its parameters and not start with the original vlaues
  • Calculate value do not use .Count before zip, because this evaluates the enumerable multiple times
  • Line 199: avoid creation of modifiable datasets on the original dataset directly
  • Use consistent values for default parameters, e.g. the defined enums

comment:16 Changed 6 years ago by fholzing

I imported and adhered to the given VisualStudio Settings from https://dev.heuristiclab.com/trac.fcgi/attachment/wiki/Documentation/DevelopmentCenter/DeveloperGuidelines/Visual%20Studio%202010%20text%20editor%20settings.vssettings (using the AutoFormat-Shortcut in VisualStudio). Either the Settings are depricated, in which case we should update them, or they don't include our preferred formatting whereby the formatting should be included i guess.

comment:17 Changed 6 years ago by fholzing

r16016: Removed unnecessary where-condition (.Where(...).Count()); Cloned the dataset before the .ToModifiable() call; Adapted the CalculateValue-Method for a single loop through the IEnumerables for the target and estimated values

comment:18 Changed 6 years ago by fholzing

I just had a closer look at the missing Property/Parameter for the factor replacement method.

At this moment, DataPartition and ReplacementMethod are defined as IFixedValueParameter but are never set this way. They are only used in the Calculate-Method, which is currently not in use.

I would like to suggest three options to think about (each with it's own (dis)advantages:

-Just use them as IFixedValueParameter
-Just use them as method-parameters
-A combination of both with the Parameter as Default, which can be overwritten (via Default-Parameter)

comment:19 Changed 6 years ago by fholzing

r16017: Added IFixedValueParameter for factory variable replacement. Unified the default values.

comment:20 Changed 6 years ago by fholzing

r16018: Unified order of IFixedValueParameter. Use FactorReplacementMethod as default for .Calculate method

comment:21 Changed 6 years ago by fholzing

r16020: Removed static calculator-variable, Changed default ReplacementMethod from Median to Shuffle, Adapted Calculation-Method adhering to the OnlineCalculators, Re-Added the condition for counting the input-parameters
