Note that the probabi...

Classification based on association rule mining has become a popular technique within the data mining community. However, it has now been emphatically shown that association rules generated solely on the basis of support and confidence are often not statistically significant i.e, the rules generated are artifacts of the particular dataset being mined rather than a relationship inherent in the u...

All of the association rule based contrast set learning techniques use support-confidence based methods and inherit their limitations. In recent years sta...
