Abstract

Market Basket Analysis is an analysis related to consumers and products in marketing. One of the successes of a company in the retail sector depends on promotion and shopping cart analysis. The data patterns generated from an association-based analysis are mostly applied by companies, one of which is the use of data mining technology. FP-Growth has been known as a reliable algorithm in terms of association, but some obstacles in its implementation in the field are often not finding a rule if using a diverse dataset. Unsupervised Learning or what is often known as grouping techniques such as K-Means, K-Medoid, and Fuzzy C-Means (FCM) can divide optimal data based on euclidean distances so that it finds better data patterns than without data sharing, especially in the case of FP-Growth. Comparisons are made by experimenting with the number of clusters 2 to 7, each of which is applied to the clustering algorithm. The results of these experiments, K- Medoid is the algorithm with the best validity value compared to other algorithms. Besides, the use of unsupervised learning techniques combined with FP-Growth can generate rules for each algorithm compared to simply applying FP-Growth.
