چکیده
Association rule mining is the most important technique in the field of data mining. The main task of association rule mining is to mine association rules by using minimum support thresholds decided by the user, to find the frequent patterns. Above all, most important is research on increment association rules mining. The Apriori algorithm is a classical algorithm in mining association rules. This classical algorithm is inefficient due to so many scans of database. And if the database is large, it takes too much time to scan the database. This paper presents many improved Apriori algorithm to increase the efficiency of generating association rules. KeywordsData mining, Apriori algorithm, minimum support threshold, multiple scan.

متن کاملIdentifying Important Factors of Arthroplasty in Patients with Degenerative Knee Osteoarthritis Based on Association Rule Mining Approach
Background and Aim: Total Knee Arthroplasty (TKA) aims to reduce the pain and improve the quality of life of patients with progressive osteoarthritis. When the indication of patients' disease is established, this type of surgery should be performed as soon as possible because patients' late attendance increases surgical complications. Therefore, identification of factors influencing the choice ...
متن کاملAn Incremental Mining Algorithm for Association Rules Based on Minimal Perfect Hashing and Pruning
In the literatures, hash-based association rule mining algorithms are more efficient than Apriori-based algorithms, since they employ hash functions to generate candidate itemsets efficiently. However, when the dataset is updated, the whole hash table needs to be reconstructed. In this paper, we propose an incremental mining algorithm based on minimal perfect hashing. In our algorithm, each can...
متن کاملIARMMD: A Novel System for Incremental Association Rules Mining from Medical Documents
This paper presents a novel system for Incremental Association Rules Mining from Medical Documents (IARMMD). The system concerns with maintenance of the discovered association rules and avoids redoing the mining process on whole documents during the updating process. The design of the system is based on concepts representation. It designed to develop our previous D-EART system. The IARMMD impro...
متن کاملAn Efficient Hash-based Association Rule Mining Approach for Document Clustering
Document clustering is one of the important research issues in the field of text mining, where the documents are grouped without predefined categories or labels. High dimensionality is a major challenge in document clustering. Some of the recent algorithms address this problem by using frequent term sets for clustering. This paper proposes a new methodology for document clustering based on Asso...
