It uses a novel fuzzy-list structure to keep the essential information for later mining process. An efficient pruning strategy is also developed to reduce the search space, thus speeding up the mining process to directly discover the FFIs. Experiments are conducted to show the performance of the proposed FFI-Miner algorithm compared to the Apriori-based and tree-based approaches in terms of execution time and the number of traversal nodes for discovering FFIs under variants of membership functions.<\/jats:p>","DOI":"10.3233\/ifs-151936","type":"journal-article","created":{"date-parts":[[2015,12,9]],"date-time":"2015-12-09T14:25:32Z","timestamp":1449671132000},"page":"2373-2379","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":37,"title":["A fast Algorithm for mining fuzzy frequent itemsets"],"prefix":"10.1177","volume":"29","author":[{"given":"Jerry Chun-Wei","family":"Lin","sequence":"first","affiliation":[{"name":"School of Computer Science and Technology, Harbin Institute of Technolgy Shenzhen Graduate School, Shenzhen, China"}]},{"given":"Ting","family":"Li","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Harbin Institute of Technolgy Shenzhen Graduate School, Shenzhen, China"}]},{"given":"Philippe","family":"Fournier-Viger","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University of Moncton, Canada"}]},{"given":"Tzung-Pei","family":"Hong","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, National Univsersity of Kaohsiung, Taiwan"},{"name":"Department of Computer Science and Engineering, National Sun Yat-sen University, Taiwan"}]}],"member":"179","published-online":{"date-parts":[[2015,10,28]]},"reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2009.12.052"},{"key":"e_1_3_1_3_2","first-page":"150","article-title":"An efficient tree-based fuzzy data mining approach","volume":"12","author":"Lin CW","year":"2010","unstructured":"Lin CW, Hong TP, Lin TC2010An efficient tree-based fuzzy data mining approachInternational Journal of Fuzzy Systems12150157","journal-title":"International Journal of Fuzzy Systems"},{"key":"e_1_3_1_4_2","doi-asserted-by":"publisher","DOI":"10.3233\/IFS-131022"},{"key":"e_1_3_1_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.asoc.2015.01.055"},{"key":"e_1_3_1_6_2","doi-asserted-by":"publisher","DOI":"10.1023\/B:DAMI.0000005258.31418.83"},{"key":"e_1_3_1_7_2","first-page":"209","article-title":"Mining fuzzy association rules","author":"Chan KCC","year":"1997","unstructured":"Chan KCC, Au WH1997Mining fuzzy association rulesProceedings of the International Conference on Information and Knowledge Management209215","journal-title":"Proceedings of the International Conference on Information and Knowledge Management"},{"key":"e_1_3_1_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0019-9958(65)90241-X"},{"key":"e_1_3_1_9_2","doi-asserted-by":"publisher","DOI":"10.1109\/TFUZZ.2003.809896"},{"key":"e_1_3_1_10_2","first-page":"3389","article-title":"Tseng, SPMF: A java open-source pattern mining library","volume":"15","author":"Fournier-Viger P","year":"2014","unstructured":"Fournier-Viger P, Gomariz A, Gueniche T, Soltani A, Wu CW, Vincent S2014Tseng, SPMF: A java open-source pattern mining libraryJournal of Machine Learning Research1533893393","journal-title":"Journal of Machine Learning Research"},{"key":"e_1_3_1_11_2","doi-asserted-by":"publisher","DOI":"10.1109\/69.250074"},{"key":"e_1_3_1_12_2","first-page":"487","article-title":"Fast algorithms for mining association rules in large databases","author":"Agrawal R","year":"1994","unstructured":"Agrawal R, Srikant R1994Fast algorithms for mining association rules in large databasesProceedings of the The International Conference on Very Large Data Bases487499","journal-title":"Proceedings of the The International Conference on Very Large Data Bases"},{"key":"e_1_3_1_13_2","first-page":"1","article-title":"The fuzzy frequent pattern tree","author":"Papadimitriou S","year":"2005","unstructured":"Papadimitriou S, Mavroudi S2005The fuzzy frequent pattern treeProceedings of the WSEAS International Conference on Computers17","journal-title":"Proceedings of the WSEAS International Conference on Computers"},{"key":"e_1_3_1_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2007.04.009"},{"key":"e_1_3_1_15_2","doi-asserted-by":"publisher","DOI":"10.3233\/IDA-1999-3504"},{"key":"e_1_3_1_16_2","first-page":"170","article-title":"An effective gradual data-reduction strategy for fuzzy itemset mining","volume":"15","author":"Hong TP","year":"2013","unstructured":"Hong TP, Lan GC, Lin YH, Pan ST2013An effective gradual data-reduction strategy for fuzzy itemset miningInternational Journal of Fuzzy Systems15170181","journal-title":"International Journal of Fuzzy Systems"}],"container-title":["Journal of Intelligent &amp;
