TMVA::Rule Class Reference
TMVA

Implementation of a rule.

A rule is simply a branch or a part of a branch in a tree. It fulfills the following:

The coefficient is found by either brute force or some sort of intelligent fitting. See the RuleEnsemble class for more info.

◆ Equal()

Bool_t TMVA::Rule::Equal ( const Rule &  other,
Bool_t  useCutValue,
Double_t  mindist 
) const

Compare two rules.

  • useCutValue:
    • true -> calculate a distance between the two rules based on the cut values if the rule cuts are not equal, the distance is < 0 (-1.0) return true if d<mindist
    • false-> ignore mindist, return true if rules are equal, ignoring cut values
  • mindist: min distance allowed between rules; if < 0 => set useCutValue=false;
