An against-expectation pattern is either an itemset that its support is out of a certain neighbor of its expected value, referred to an against-expectation itemset or an association rule generating by an against-expectation itemset, referred to an against-expectation rule. The techniques for mining against-expectation patterns are previously undeveloped. Present algorithm for identifying against-expectation patterns is based on the nearest- neighbor graph and correlation analysis techniques. We experimentally evaluate our algorithms and demonstrate that our approach is efficient and promising. ER -
