The main goal of this method is to solve the updating problem of association rules after a number of new records have been added to a database. The overall approach towards incremental mining is to make use of previously mined knowle ...

Discovery Robust Knowledge from Databases that Change
... The robustness of a rule could be different in different database states. E.g.: Suppose there are two db states d1 and d2 of a given db. To reach a state inconsistent with r, we need to delete 10 tuples in d1 and only 1 tuple in d2. ...
