Fuzzy Gamma Naive Bayes (R6 class)

R6 implementation of the Fuzzy Gamma Naive Bayes classifier. Create the model with FuzzyGammaNaiveBayesModel$new(), train it with $fit(train, cl) and classify new observations with $predict(newdata). The functional interface FuzzyGammaNaiveBayes() trains and returns an object of this class.

Super class

FuzzyClassifier -> FuzzyGammaNaiveBayes

Methods

FuzzyGammaNaiveBayes$new()

Create a new (untrained) classifier.

Usage

FuzzyGammaNaiveBayes$new(fuzzy = TRUE)

Arguments

fuzzy

See FuzzyGammaNaiveBayes().

---

FuzzyGammaNaiveBayes$clone()

The objects of this class are cloneable with this method.

Usage

FuzzyGammaNaiveBayes$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
