DWFuzzyGammaNaiveBayes: Double Weighted Fuzzy Gamma Naive Bayes

In FuzzyClass: Fuzzy and Non-Fuzzy Classifiers

Double Weighted Fuzzy Gamma Naive Bayes

Description

DWFuzzyGammaNaiveBayes Double Weighted Fuzzy Gamma Naive Bayes

Usage

DWFuzzyGammaNaiveBayes(train, cl, cores = 2, fuzzy = TRUE, wdelta, weta)

Arguments

train	matrix or data frame of training set cases.
cl	factor of true classifications of training set
cores	kept for backward compatibility; prediction is vectorized and does not start parallel workers (default = 2)
fuzzy	boolean variable to use the membership function
wdelta	vector weight each class
weta	vector weight each feature

Value

A vector of classifications

Examples

set.seed(1) # determining a seed
data(GamWeightData)

# Splitting into Training and Testing
split <- caTools::sample.split(t(GamWeightData[, 1]), SplitRatio = 0.7)
Train <- subset(GamWeightData, split == "TRUE")
Test <- subset(GamWeightData, split == "FALSE")
# ----------------
# matrix or data frame of test set cases.
# A vector will be interpreted as a row vector for a single case.
test <- Test[, -4]
fit_NBT <- DWFuzzyGammaNaiveBayes(
  train = Train[, -4],
  cl = Train[, 4], cores = 2,
  wdelta = c(2.002/6,1.998/6,2.000/6),
  weta = c(3/10,2/10, 5/10)
)

pred_NBT <- predict(fit_NBT, test)

head(pred_NBT)
head(Test[, 4])
