The ID3 algorithm uses the information gain size to determine what features the current node should use to construct the decision tree, and uses the calculated maximum gain of information to establish the current node of the decision tree. Here we give a concrete example of information gain calcu...
ID3 algorithm is to construct the decision tree by employing a top-down, greedy search through the given sets to test each attribute at every tree node. In order to select the attribute that is most useful for classifying a given sets, we introduce a metric information gain. C4.5 is an ...

In this paper, Fuzzy ID3 algorithm is used, a popular and particularly efficient method, to construct fuzzy decision tree. We use weighted fuzzy production rules generated from fuzzy decision tree to establish early-warning system of financial risk. In addition, a new method is proposed, based ...
Conventional ID3 algorithm is modified by firstly horizontally splitting the sample of RFM dataset and then some mathematical calculations are applied in order to construct decision tree and then to predict future customer behaviors by matching pattern. This proposed algorithm significantly reduces the ...
