Abstract

Market Basket Analysis is used for many applications like online marketing, recommendation engines, information security, etc. Over the past few years, it has been one of the hot topics among research groups as its widely used e-commerce site to recommend related products or arrangements of layouts on the basis of frequently purchased items in supermarkets and fixing consumer index price as per consumer’s demands. In this paper, we have focused on two widely used market basket analysis algorithms i.e. Apriori algorithm and FP-growth algorithm. This paper mainly compares these two algorithms and compares the efficiency on the basis of database sizes, time complexity and space complexity. As a finding of comparison of these two algorithms we discovered that the Apriori algorithm required more time complexity while Fp-growth required more space complexity. Apriori algorithm can be used when there are no time constraints but low space available whereas FP-growth Algorithm used for low time constraint as it uses tree repeatedly to add new types of transactions to reduce time complexity.
基于先验算法和FP-Tree算法的购物篮分析
购物篮分析用于许多应用程序,如在线营销,推荐引擎,信息安全等。在过去的几年里,由于其广泛使用的电子商务网站根据消费者在超市经常购买的商品推荐相关产品或安排布局,并根据消费者的需求确定消费者指数价格,因此一直是研究小组的热点之一。在本文中,我们重点研究了两种广泛使用的市场篮子分析算法,即Apriori算法和FP-growth算法。本文主要对这两种算法进行比较,并在数据库大小、时间复杂度和空间复杂度的基础上对效率进行比较。通过对两种算法的比较,我们发现Apriori算法需要更多的时间复杂度,而Fp-growth算法需要更多的空间复杂度。Apriori算法可以在没有时间约束但可用空间较小的情况下使用,而FP-growth算法可以在时间约束较低的情况下使用,因为它反复使用tree来添加新类型的事务,以降低时间复杂度。
