How to tell two categorical arrays with different categories names are the same

3 views (last 30 days)
Assume I have two categorical arrays as for example the following:
X=[1,1,2,3];
y=[3,3,1,2];
The two arrays have different classes names (categories) but in the classification task they have the same classes. How could I tell that the two arrays are the same (have the same categories)?

You don't have categorical arrays, you have numeric arrays. If you had categorical arrays, you'd just look at their categories.
