: : 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?
: 我好像知道了
: 我搞错题目的意思了，我以为 Soil_Type 是 target (leaf)
: 其实 leaf 是 Cover_Type (？)
