Abstract: Rule induction is an area of machine learning in which formal rules are extracted from a set of observations or training dataset. Inducted rules can be expressed as a final result of the decision tree in which each branch represents a possible scenario of decision and its outcome. Existing decision learning algorithms like Iterative Dichotomiser (ID3) is an attribute centered method which may introduce unnecessary attributes in the classification rules. To overcome the problem, coverage and confidence measures are applied to select the most promising attribute-value at each step. The proposed approach is granule centered in which, instead of focusing on the selection of a suitable partition, i.e., a family of granules is defined, a teach step, by values of an attribute. This paper is concentrated on the selection of a single granule. The decision tree learning algorithm ID3 and granular network are successfully applied for information table of test dataset of seismic vulnerability of urban areas in Tehran, capital of Iran.
