....and difficulties which are part of a lot of research which is currently going on. Contributions to tackle a number of these difficulties can be found in [4] in [6] and in [7] Liu, Ma Wong, even proposed an improvement of their original CBA (classification based on associations) system [3] in [8] to cope with those weaknesses. In spite of the fact that the presented adaptations of CBA are valuable, some important issues still remain unsolved. Our goal is to address them in this paper. The potential weakness which we were able to determine is situated in the way CBA sorts its (class) ....

Identifying weaknesses and proposing adaptations to CBA 3.1 Using intensity of implication to sort the CARs A profound examination of the algorithm learns us that a potential weakness is the way the rules are sorted. Since rules are inserted in the classifier following the sorted ....
