Decision Tree

finis Tree A conclusiveness shoetree diagram is a model that is both prognostic and descriptive. It is c anyed a decision tree because the resulting model is presented in the relieve oneself of a tree structure. decisiveness trees argon a streamer tool in data mining. Decision trees be for the most part favored over other nonparametric techniques because of the readability of their versed hypotheses and the cleverness of training and evaluation. Decision trees rotter be utilise in many different situations to assist in work come in a problem. Decision trees can be extremely worthy when one is faced with a sequential decision problem. Decision trees can provide a detailed representation of all the paths that may prevail within a decision problems formulation horizon according to the alternatives associated with for each one decision and mathematical outcomes associated with each uncertain event. (Golub, 1997) Decision trees are read from unexpended to right . Decision trees are generally learned by delegacy of a gain down growth procedure, which starts from the root guest 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 thence 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 themselv! es in terms of the cost function. A decision tree can be judgment of as a type of a footmark 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 rattling concise at that.
