Classification by naive bayes

Ka13nKa13n Member Posts: 5 Newbie
Dear Community

Good day and Merry Christmas!
I'm still new to this field and try to explore as much knowledge as I can now.... 
I've a question regarding using naive bayes for classification.

I got a data set with words, sum (in total) and sum (in document), for the further step I wanna use the text mining data to classified the paper which I collected.
However, my process keeps showing ''the example set is empty'', which can be referred to below XML. 
Is there any solution for the wrong output? If do, can any expert advise me? 
Thanks in advance and wish you all have a nice holiday! :smile:

    hi @Ka13n can you also post your repository data set "Acceptance 100 rfef result"? We cannot run your process and replicate your result without it.

    Dear Scott

    Thanks for spending time on my process, I've PM you regarding the repository.
    Please kindly find the data set and let me know if anything needed to solve the problem.

    ok thank you I have your data set. So yeah...I can see why you have an empty set. You're trying to ask Naive Bayes to do classification where the target/label is different for every row. That's an impossible problem.

    Can you backtrack and explain what exactly you're trying to do?

    I want to do like categorized the words or some approach in order to classify the papers which I collected.
    Don't know if this is possible, and thanks for helping me on my dumb question...

    ah ok. I'd recommend looking at this thesis that was written not long ago. I believe it is more in line of what you're trying to do.
