Synonyms C4.5 ; CART ; Classification tree Definition A decision tree is a tree-structured classification model, which is easy to understand, even by nonexpert users, and can be efficiently induced from data. The induction of decision trees is one of the oldest and most popular techniques for...
Under these conditions, the cash flows if successful from the second investment have a NPV: 5 900 NPV = -1,500 +(1.15)t t =1 =-1,500 + 900 ·A 5 0.15 = 1,517 So what does the decision tree for this project look like? • Backward Induction: one makes decisions in reverse...

This paper focuses on the variance introduced by the dis- cretization techniques used to handle continuous attributes in decision tree induction. Di erent discretization procedures are rst studied em- pirically, then means to reduce the discretization variance are proposed. The experiment shows that ...
Our time-series tree has a time sequence in its internal node, and splits examples based on similarities between a pair of time sequences. We first define our standard example split test based on dynamic time warping, then propose a decision tree induction procedure for the split test. ...
