Due to some defaults of rough sets based on data analysis,the multiscale variate is introduced to found the univariate multiscale rough set model by using the idea of variable precision rough set model.So the data can be analyzed in multiscale and variability in order to further improve the ability of Noise suppression,and availably acquire the decision rule.From the interrelation of multiscale value s and function(fs),the effect of value s for the approximation quality of classification is discussed to lay the foundation for the muliscale description of information attribute.The example of computing and analyzing with the proposed method shows it s effectiveness.
