Set Overlap in Mining of Frequent Itemsets
نویسنده
چکیده
An important module of soft computing methods is the set overlap operation. If a query set is tested with a large pool of source sets, the signature-based or the inverted-file methods are used to reduce the cost of operation. The paper introduces a modified version of the inverted-file approach, which yields in lowest costs for sparse input samples, i.e. where the number of records containing an element is relatively low.

MINING FUZZY TEMPORAL ITEMSETS WITHIN VARIOUS TIME INTERVALS IN QUANTITATIVE DATASETS
This research aims at proposing a new method for discovering frequent temporal itemsets in continuous subsets of a dataset with quantitative transactions. It is important to note that although these temporal itemsets may have relatively high textit{support} or occurrence within particular time intervals, they do not necessarily get similar textit{support} across the whole dataset, which makes i...

Discovery of hidden and valuable knowledge from large data warehouses is an important research area and has attracted the attention of many researchers in recent years. Most of Association Rule Mining (ARM) algorithms start by searching for frequent itemsets by scanning the whole database repeatedly and enumerating the occurrences of each candidate itemset. In data mining problems, the size of ...
متن کاملData sanitization in association rule mining based on impact factor
Data sanitization is a process that is used to promote the sharing of transactional databases among organizations and businesses, it alleviates concerns for individuals and organizations regarding the disclosure of sensitive patterns. It transforms the source database into a released database so that counterparts cannot discover the sensitive patterns and so data confidentiality is preserved ag...
متن کاملFast Algorithms for Mining Generalized Frequent Patterns of Generalized Association Rules
Mining generalized frequent patterns of generalized association rules is an important process in knowledge discovery system. In this paper, we propose a new approach for efficiently mining all frequent patterns using a novel set enumeration algorithm with two types of constraints on two generalized itemset relationships, called subset-superset and ancestor-descendant constraints. We also show a...
متن کاملMining Frequent Closed Itemsets with the Frequent Pattern List
The mining of the complete set of frequent itemsets will lead to a huge number of itemsets. Fortunately, this problem can be reduced to the mining of frequent closed itemsets (FCIs), which results in a much smaller number of itemsets. The approaches to mining frequent closed itemsets can be categorized into two groups: those with candidate generation and those without. In this paper, we propose...
متن کاملMining All Non-derivable Frequent Itemsets
Recent studies on frequent itemset mining algorithms resulted in significant performance improvements. However, if the minimal support threshold is set too low, or the data is highly correlated, the number of frequent itemsets itself can be prohibitively large. To overcome this problem, recently several proposals have been made to construct a concise representation of the frequent itemsets, ins...
