Naive Bayes Geometric Classifier
FuzzyGeoNaiveBayes(train, cl, cores = 2, fuzzy = T)
train |
matrix or data frame of training set cases. |
cl |
factor of true classifications of training set |
cores |
how many cores of the computer do you want to use (default = 2) |
fuzzy |
boolean variable to use the membership function |
A vector of classifications
