product recommendation example), and one will be used as a target
( class ). Setting the usage to active is shown at lines 9, 17, 25, and 34.
The second option we use is outlier treatment, which is set at lines 6,
15, 23, and 32. We have chosen, in this example, to let the system
decide the treatment for education and marital-status but to leave the
capital-gain “as is.” Of course, more general code can be written,
especially in conjunction with a user interface, to ask for attribute
names, together with outlier treatment, usage, and others that can
be tuned at the logical attribute level.
