Classification Learner - importing character variables?

Hello there, I hope someone here can help me with a probably trivial problem. I want to use the Classification Learner App. I have a dataset with a numerical response (years) and a number of character variables as predictors or, if possible, a mix of numerical and character variables as predictors. It seems like the Classification Learner App doesn't recognize character variables and I can't the the app to import my predictor variables. Does anyone have a solution for this??

Cheers Niclas

Hi Niclas,

I was looking at the documentation page, and it mentions that the predictors cannot be of any type other than numeric. I was trying a few examples and it allows an import only with numeric data types. Here is the documentation link that explains the same:

http://www.mathworks.com/help/stats/select-data-and-validation-for-classification-problem.html

You may have to edit the predictors to be numeric, or maybe you could take in the numeric values of the character predictors.

Hope this helps!

Hello Geetu

You have to import your response as a separate file, so you have an input array of X rows and Y columns, and a response of X rows.
