Often in higher order data mining (HOM) applications we need to use incomplete patterns received from different sources. In this paper, a solution is proposed for mining new patterns from incomplete or corrupted patterns received from the sources. The solution is based on a relation representation for the patterns, this representation may be used both for pattern discovery from incomplete information,...

However there are cases when we canpsilat access directly the raw data, such as: (i) institutions interested in sharing knowledge may not be allowed to share the raw data; (ii) data is in form of streams and it is only temporarily available for processing; (iii) finally there may also be limits on the computation speed that could...
