'How to address 'Input Mapped Classifier' message in Weka
I am trying to test a machine learning model produced from a training dataset that is triple the size of my test dataset. When I upload my test dataset into weka for training I get a message asking if I would like to "Input Mapped Classifier". I clicked yes and my results showed multiple question marks and a confusion matrix with very few results in it. I was wondering if there is a way to get around this and improve the output? Thank you for your help!
