Re: Naive Bayes Classifier for Marketing data
Mandeep, I just worked through a similar example using the same data set but using the logistic regression learner. In order to use Naive bayes, you would need to convert the continuous variables to categorical variables by binning.

Re: Naive Bayes Classifier for Marketing data
Not to be rude, but how would you think you could use binning in a map-reduce program? Seriously, what ideas can you come up with for this? What are the problems you see?

Re: Naive Bayes Classifier for Marketing data
Binning refers to the reduction of a continuous variable to a categorical variable. This is done by defining intervals which partition all possible values and testing the continuous variable to see which interval it falls into. Why would map-reduce have anything to do with this?
