Welcome. 1 Introduction. 2 … Web3.1 Splitting criteria If we split a node Ainto two sons A Land A R (left and right sons), we will have P(A L)r(A L) + P(A R)r(A R) ≤P(A)r(A) (this is proven in [1]). Using this, one obvious way to build a tree is to choose that split which maximizes ∆r, the decrease in risk. There are defects with this, however, as the following example shows:
