Fuzzy Gaussian Naive Bayes (Zadeh-based) (R6 class)

R6 implementation of the Fuzzy Gaussian Naive Bayes (Zadeh-based) classifier. Create the model with FuzzyGaussianNaiveBayesModel$new(), train it with $fit(train, cl) and classify new observations with $predict(newdata). The functional interface FuzzyGaussianNaiveBayes() trains and returns an object of this class.

Super class

FuzzyClassifier -> FuzzyGaussianNaiveBayes

FuzzyGaussianNaiveBayes$new()

Create a new (untrained) classifier.

Usage

FuzzyGaussianNaiveBayes$new(fuzzy = TRUE)

Arguments

fuzzy

See FuzzyGaussianNaiveBayes().

---

FuzzyGaussianNaiveBayes$clone()

The objects of this class are cloneable with this method.

Usage

FuzzyGaussianNaiveBayes$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
