Abstract (EN)The concept of valued tolerance is introduced as an extension of the usual concept of indiscernibility (which is a crisp equivalence relation) in rough sets theory. Some specific properties of the approach are discussed. Further on the problem of inducing rules is addressed. Properties of a “credibility degree” associated to each rule are analysed and its use in classification problems is discussed.
