Decision trees can provide a detailed representation of all the paths that may prevail within a decision problems planning horizon according to the alternatives associated with for each one decision and contingent outcomes associated with each uncertain event. (Golub, 1997) Decision trees are read from left field to right. Decision trees are gene rally learned by inwardness of a gain down growth procedure, which starts from the root customer and greedily chooses a split of the data that maximizes some be function, usually a measure of the impurity of the sub samples implicitly defined by the split. After choosing a split, the sub samples are thusly mapped to the cardinal children nodes. This procedure is then recursively applied to the children, and the tree is grown until some stopping criterion is met. The tree is then used as a starting point for a bottom up search, performing a pruning of the tree. This eliminates nodes that are redundant or are unable to pay for themselves in terms of the cost function. A decision tree can be judgment of as a type of a mark map. On the tree, each line represents a trail segment to be traversed. Each point of interconnection,known as a node, indicates where any of... great dept and ratt ling concise at that.
