Abstract Some learning algorithms of interval-valued attributes are developed in the disorderly situation. The ordinal relation between condition attributes and decision attributes is not taken into account. In this paper, aiming at the defects of the original algorithms, a monotonic decision tree algorithm is proposed to deal with monotonic classification of interval-valued attributes. The possibility degree is used to determine the order relation of interval-valued attributes, the rank mutual information is utilized to measure the monotonic consistency, and the expanded attributes are selected by maximizing the rank mutual information. Furthermore, unstable cut-points are applied to the construction process of interval-valued attributes decision tree to reduce the computing number of rank mutual information and improve the computational efficiency. The experimental results show that the algorithm improves the efficiency and testing accuracy.

Key words： Interval-Valued Attribute Monotonic Classification Possibility Degree Monotonic Decision Tree
