Abstract: The interval concept lattice theory is a new method of mining objects based on interval parameters.It can more accurately deal with uncertain information.Interval parameters α and β can determine interval concepts and lattice structure,and then affect extracted decision rules.In order to solve the optimization problem of interval parameters,firstly we combined the theories of interval concept lattice and three-way decision-theoretic rough set,and then put forward three-way decision space theory.Secondly,according to the theory,the extension of interval concept was divided into positive region.Megative region and boundary region,moreover,the three-way decision rules and decision loss function were proposed.Through adjusting interval parameters,we can find more credible decision rules,and then optimize interval parameters.Finally we verified the model by an example.
