Spark solutions for discovering fuzzy association rules in Big Data Fernández Basso, Carlos Jesús Ruiz Jiménez, María Dolores Martín Bautista, María José Big Data Fuzzy frequent itemset Fuzzy association rules Spark The research reported in this paper was partially supported the COPKIT project from the 8th Programme Framework (H2020) research and innovation programme (grant agreement No 786687) and from the BIGDATAMED projects with references B-TIC-145-UGR18 and P18-RT-2947. The high computational impact when mining fuzzy association rules grows significantly when managing very large data sets, triggering in many cases a memory overflow error and leading to the experiment failure without its conclusion. It is in these cases when the application of Big Data techniques can help to achieve the experiment completion. Therefore, in this paper several Spark algorithms are proposed to handle with massive fuzzy data and discover interesting association rules. For that, we based on a decomposition of interestingness measures in terms of α-cuts, and we experimentally demonstrate that it is sufficient to consider only 10equidistributed α-cuts in order to mine all significant fuzzy association rules. Additionally, all the proposals are compared and analysed in terms of efficiency and speed up, in several datasets, including a real dataset comprised of sensor measurements from an office building. 2022-03-01T07:22:00Z 2022-03-01T07:22:00Z 2021-07-24 info:eu-repo/semantics/article Carlos Fernandez-Basso, M.
