Introduction,ion to market basket analysis . The goal of market basket analysis is to better understand the purchase behavior of customers in supermarkets. Transaction data recorded by point-of-sale systems in supermarkets is analysed. We assume there is a set . = {.., …, .. } of possible items of goods and sAgility 发表于 2025-3-23 19:10:57
Data Matrices matrix. An example of such a data matrix with general values is given in Sect. 2.1. However, we are interested only in a simple form of data matrices. This means that we consider data matrices with positive integer numbers as their only values, see Sect. 2.2. Association rules were defined in a丛林 发表于 2025-3-24 01:56:56
4ft-quantifiersion to the GUHA procedure ASSOC. These are introduced in Sect. 4.1. There is also a possibility to use various measures of interestingness of association rules together with suitable thresholds for their values to define additional 4ft-quantifiers. An overview of well known measures of interestingneIncorruptible 发表于 2025-3-24 05:04:27
Useful Resultsf 4ft-quantifiers is defined by a relatively simple condition concerning frequencies from 4ft-tables. However, the proof that a particular 4ft-quantifier belongs to a particular class of 4ft-quantifiers sometimes requires a relatively complex computation. This is especially true for statistically mo食道 发表于 2025-3-24 09:29:00

Deduction Rules truthfulness of a given association rule implies truthfulness of an additional rule with the same 4ft-quantifier. Criteria of soundness of such deductions rules are found for important classes of 4ft-quantifiers. It is shown that the question of soundness of a given deduction rule can be converted
