Fuzzy Poisson Naive Bayes (R6 class)

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

Super class

FuzzyClassifier -> FuzzyPoissonNaiveBayes

FuzzyPoissonNaiveBayes$new()

Create a new (untrained) classifier.

Usage

FuzzyPoissonNaiveBayes$new(fuzzy = TRUE)

Arguments

fuzzy

See FuzzyPoissonNaiveBayes().

---

FuzzyPoissonNaiveBayes$clone()

The objects of this class are cloneable with this method.

Usage

FuzzyPoissonNaiveBayes$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
