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"
