Hello, I have a problem concerning my project and I would really like to know what I am doing wrong..
I have an example set where there is a column named activities that include walking, sitting, joking, standing etc and I want to evaluate the performance of decision tree model in this set. The problem is when I get to performance matrix all the values in activites are compaired only to walking...and I get no precision for the other values (sitting, joking etc). Can someone help? I'm providing the photos of my project. Thank you in advance!
