In Data mining applications, which often involve complex data like multiple heterogeneous data sources, user preferences, decision-making actions and business impacts etc., the complete useful information cannot be obtained by using single data mining method in the form of informative patterns as that would consume more time and space, if and only if it is possible to join large relevant data sources for discovering patterns consisting of various aspects of useful information. We consider combined mining as an approach for mining informative patterns from multiple data-sources or multiple-features or by multiple-methods as per the requirements. In combined mining approach, we applied Lossy-counting algorithm on each data-source to get the frequent data item-sets and then get the combined association rules. In multi-feature combined mining approach, we obtained pair patterns and cluster patterns and then generate incremental pair patterns and incremental cluster patterns, which cannot be directly generated by the existing methods. In multi-method combined mining approach, we combine FP-growth and Bayesian Belief Network to make a classifier to get more informative knowledge.
