Hi, i am working with the data set of multi class labels can any one help me how to compare ROCs for such multi class labels ,even i couldn't find how to plot the results of multi class labels. I have used Binary2Multiclass learner and Polynomial by binomial classification but i am not getting the curve. I would feel better if you send the related operators with wiring. Thanks in advance...
I am a newbie in Rapid Miner.
I am also facing same problem, when try to create a logistic model, here my label have more than 2 categories.
I know Logistic model is for modelling on Binomial Labels, But here I am asking that "How to Implement Multinomial Logistic Model in Rappid Miner"
