Hi,
I am a little confused with the requirement of hw2.
The requirement says,
"We are interested in whether a single nominal attribute
with 40 possible values or 40 binary attributes is better"
Is this means, we should build classification tree according to
these 40 binary attributes separately, and compare the result to
"attribute with 40 values"?
ex: according to "binary attribute 1"
v.s.
according to "40-value attributes"
Or should we build a classification tree according to 40 binary
attributes all together?
ex: according to "binary attribute 1~40"
v.s.
according to "40-value attributes"
If so, how to do this?
