Description
Summary:With the view of granular computing, there are different granules at different levels of scale in data sets having hierarchical scale structures. In this paper, the concept of multi-scale decision systems is introduced firstly, then a formal approach to rule acquisition measured at different levels of granulations is proposed, and some algorithms for rule acquisition in consistent multi-scale decision systems are proposed with illustrative examples.
