To overcome this problem a data partitioning method using MapReduce model is proposed. In this model, three MapReduce tasks are implemented to improve the performance of frequent itemset mining in parallel. In

In this section, we describe an efficient implementation for FREIGHT. Recall that, for every vertex v that is loaded, FREIGHT uses Equation (2) to find the block with the highest score among up to k options. A simple method to accomplish this task consists of explicitly evaluating the score...
With a hyperedge partitioning method, each hyperedge appears in only one partition, while vertices may be cut and replicated in more than one partition. As seen in Fig. 1 (c), the cutsize is 3, since there are three vertices (v2, v6 and v7) being in cut state. We assume that ...

First, we briefly introduce the PREF method. Second, we show that two types of duplicates, tuple-level duplicates and table-level duplicates, exist in a database partitioned by PREF in Sections 2.2 and 2.3. Third, we show that due to its tree-based partitioning schemes, query processing on...
11.A computer-implemented method of data mining, comprising:fetching data from a relational server;locally partitioning the data into a subset of the data; andbuilding a mining model that detects a data pattern based at least in part upon the subset of the data. ...
In this study, we present K_means clustering algorithm that partitions an image database in cluster of images similar. We adapt K_means method to a very special structure which is quadree. The goal is to minimize the search time of images similar to an image request. We associate to each...

A system that effectuates fetching a complete set of relational data into a mining services server and subsequently defining desired partitions upon the fetched data is provided. In
