Rough-set belief rule model using multinomial subjective logic

In accordance with the uncertainty of decision rules extraction process in boundary region of the rough set, this study proposes a rough-set belief rule model using multinomial subjective logic. The model builds the belief rule expectation for classification and recognition. It not only considered the effects of single condition attributes on decision, but also the multi-attributes. Finally, the example analysis and comparison with the R_0.5(X) model indicates the validity and advantage of this model.
