Fuzzy Binomial Naive Bayes

Description

FuzzyBinomialNaiveBayes Fuzzy Binomial Naive Bayes

Usage

FuzzyBinomialNaiveBayes(train, cl, cores = 2, fuzzy = TRUE)

Arguments

fuzzy

boolean variable to use the membership function

Value

A vector of classifications

Examples

set.seed(1) # determining a seed
class1 <- data.frame(vari1 = rbinom(100,size = 10, prob = 0.2),
                     vari2 = rbinom(100,size = 10, prob = 0.2),
                    vari3 = rbinom(100,size = 10, prob = 0.2), class = 1)
class2 <- data.frame(vari1 = rbinom(100,size = 10, prob = 0.5),
                     vari2 = rbinom(100,size = 10, prob = 0.5),
                    vari3 = rbinom(100,size = 10, prob = 0.5), class = 2)
