Bug Report, WEKA:Naive Bayes
Rapidminer 4.5

Dear All,

I hope this is a correct bug report.
I wasn't sure where to post.

The WEKA Naive Bayes refuses to run:
it claim's ComplementNaiveBayes: Cannot handle multi-valued nominal attributes!
But I think it should use weka.classifiers.bayes.NaiveBayes, not ComplementNaiveBayes!

I used the following data, and loaded it inside WEKA to confirm that NaiveBayes runs fine there.

Data:
"Day";"Outlook";"Temperature";"Humidity";"Wind";"PlayTennis"
"Dl";"Sunny";"Hot";"High";"Weak";"No"
"D2";"Sunny";"Hot";"High";"Strong";"No"
"D3";"Overcast";"Hot";"High";"Weak";"Yes"
"D4";"Rain";"Mild";"High";"Weak";"Yes"
"D5";"Rain";"Cool";"Normal";"Weak";"Yes"
"D6";"Rain";"Cool";"Normal";"Strong";"No"
"D7";"Overcast";"Cool";"Normal";"Strong";"Yes"
"D8";"Sunny";"Mild";"High";"Weak";"No"
"D9";"Sunny";"Cool";"Normal";"Weak";"Yes"
"Dl0";"Rain";"Mild";"Normal";"Weak";"Yes"
"Dl1";"Sunny";"Mild";"Normal";"Strong";"Yes"
"Dl2";"Overcast";"Mild";"High";"Strong";"Yes"
"Dl3";"Overcast";"Hot";"Normal";"Weak";"Yes"
"Dl4";"Rain";"Mild";"High";"Strong";"No"

Hi Wessel,
we have a bugtracker at bugs.rapid-i.com. This is the right place for such nice and detailed bug reports I will copy this one and paste it there.

Oh,
one short hint: You just could replace the WEKA Bayes with the rapid miner Naive Bayes learner. This should work anyway. And the learner doing exactly the same.

I'm making a new account.

Since my forum account doesn't work?

Yes,
unfortunately the forum and the bug tracker use incompatible table formats. You will have to create a new login if you want to report bugs.

Greetings,
  Sebastian

PS: I took a look on the matter and saw, that the W-NaiveBayes operator is deprecated. So this bug has got reaaally low priority, because we have some bugs on not deprecated things, which come first...
