Abstract—The paper discusses the methods used to rough set theory knowledge to discovery from decision tables. From this ways dynamic reduct. Discovery relative static and dynamic reducts, discovery frequent sets, discovery decision rules and calculate stability coefficients for objects from a decision table. The most important and matchless feature of dynamic reduct is ability to calculate stability coefficients for every object from decision table using different methods. In this study we present some statistical arguments showing the introduced stability coefficient of dynamic reducts are proper measures of their quality.

Index Terms—Dynamic reduct, Decision table, Rough set, Stability coefficients.
