Embodiment Construction

[0030] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0031] It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second" and the like are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance.

[0032] The frequent itemset mining algorithm in the prior art directly processes the entire original data set, and the amount of data corresponding to the original data set is relatively large (for example, if the size of the original data set exceeds the preset size, it is considered that the original data set corresponds to If the amount of data is relativel...

Abstract

Embodiments of the invention provide a frequent item set mining method and device, a storage medium and electronic equipment. The mining method comprises the steps of obtaining an original data set; dividing the original data set into a plurality of sub-data sets; calculating at least one frequent item set of each sub-data set in the plurality of sub-data sets; summarizing all the frequent item sets of all the sub-data sets to obtain at least one candidate frequent item set of the original data set; and screening out a frequent item set of the original data set from the at least one candidatefrequent item set. By means of the method, the mining time of the frequent item set can be shortened.

Description

technical field [0001] The present application relates to the technical field of data mining, and in particular to a frequent itemset mining method, device, storage medium and electronic equipment. Background technique [0002] Frequent itemset mining has always been one of the most active fields in data mining. It has a very wide range of applications in real life, for example, it is widely used in many research fields such as data mining, software error detection, spatiotemporal data analysis, biological analysis, etc. Due to its practical significance, frequent itemset mining has attracted extensive attention. [0003] At present, common frequent itemsets mining algorithms include Apriori (association rule algorithm) algorithm, FP-Growth algorithm and Eclat algorithm, so frequent itemsets can be mined through the above three algorithms. [0004] In the process of realizing the present invention, the inventors found the following problems in the prior art: when the amoun...
