Abstract :
Discrete features play an important role in data mining. How to best discretize continuous features has always been a NP-hard problem. This paper introduces diverse taxonomies in the existing literature to classify discretization methods, as well as idea and drawbacks of some typical methods. Furthermore, a comparison of these methods is studied. It´s essential to select proper methods depending on learning environment. At last, the thought of choosing the best discretization methods in association analysis is proposed as future research.
