Hi, I am new to RapidMiner.

I would like to predict Credit Payment 'yes or no' outcome with at least 2 method (e.g Naive Bayes/Decision Tree/k-mean etc.), however all of the prediction returns a no.
Unlike a usual yes/no this attribute has 3 values in the excel data: yes, no and unknown. 
I am using Naive Bayes, decision tree and have set the attribute to label, polynominal for prediction.

Appreciate any help in advance.

    Hi @Coralion,

    It's difficult to answer without analysing your data.
    Maybe have you got a highly imbalanced training set ...??

    Can you please share your data ?

    Sure @lionelderkrikor

    As attached. There are some 'unknown' values for education and job attribute. Those could be the affecting factors.
