The date mining based on big data was a very important field. In order to improve the mining efficiency, the mining algorithm of frequent itemsets based on mapreduce and FP-tree was proposed, namely, MAFIM algorithm. Firstly, the data were distributed by mapreduce. Secondly, local frequent itemsets were computed by FP-tree. Thirdly, the mining results were combined by the center node. Finally, global...
Considering the requirement to build space and ground integrated training, mission command and decision-making space flight simulator, with the development of manned space engineering, a standards-based HLA astronaut training, command and decision-making integrated space and ground simulator distributed architecture was presented. Firstly the system structure composed of the spacecraft, telemetry...
Traditional algorithms for mining maximum frequent itemsets in local database and for mining global frequent itemsets do not suit mining of maximum frequent itemsets in distributed multimedia database. As far as we know, a little research of mining global maximum frequent itemsets has been done. Therefore, the paper proposes an algorithm for fast mining maximum frequent itemsets in distributed multimedia...
