In this paper, we propose a new decision-tree induction algorithm based on clustering named Clus-DTI. Our intention is to investigate how clustering data as a part of the induction process affects the accuracy and complexity of the generated models. Our performance analysis is not based solely ...

This simplified algorithm is is the basis for all current top-down decision tree induction algorithm. Nevertheless, its assumptions are too stringent for practical use. For instance, it would only work if every combination of attribute values is present in the training data, and if the training ...

RainForest, for example, adapts to the amount of main memory available and applies to any decision tree induction algorithm. The method maintains an AVC-set (where “AVC” stands for “Attribute-Value, Classlabel”) for each attribute, at each tree node, describing the training tuples at ...

We say that a distributed learning algorithm L d (e.g., for decision tree induc- tion fromdistributed data sets) is exact with respect to the hypothesis inferred by a batch learning algorithm L (e.g., for decision tree induction from a cen- tralized data set) if the hypothesis produced...
