Abstract
Due to the exponential increase of real-time data monitoring systems, the extraction of frequent item (Frequent item set mining) set from large uncertain database is the challenging task. The existing parallel mining algorithm for frequent item sets includes the limitations in terms of more memory usage and excessive run time even for less amount of data. To overcome this problem, the FiDoop based item set mining algorithm is proposed by using map reduce framework. It is used to improve the performance of load balancing operation in an uncertain database for computing frequent patterns. This system includes data uploading, preprocessing, threshold, find support and confidence, merge and result. Initially, the data is selected from the dataset and uploaded in the server. Afterwards, the preprocessing stage removes columns which contains unwanted entries. The information is analyzed and partitioned to compute threshold value. These data are classified depends on threshold values and the clustering algorithm is used to find high support and confidence values among clusters to discover frequent item. Finally, those frequent item sets are merged to acquire a frequent pattern. The proposed system is mainly developed for improving the accuracy and it is evaluated based on the performance measures of accuracy, memory usage and execution time.
