Introduction

In the realm of data mining, the Apriori algorithm plays a pivotal role in forming association rule mining. This algorithm involves the extraction of information from a database, followed by the production of frequent items/items and candidate generation. The ultimate goal is to obtain a minimum support value and a minimum confidence. However, in large databases, the Apriori algorithm tends to produce numerous frequent items/items, which is caused by the recurring candidate generation process and the need to record databases repeatedly.

The Limitations of Traditional Apriori Algorithm

The traditional Apriori algorithm has several limitations, particularly in large databases. One of the primary limitations is the production of numerous frequent items/items, which can lead to a significant increase in the complexity of the analysis. This is due to the recurring candidate generation process, which requires the algorithm to record databases repeatedly. As a result, the traditional Apriori algorithm can be computationally expensive and time-consuming.

The Need for Optimization

In order to overcome the limitations of the traditional Apriori algorithm, there is a need for optimization. One of the strategies applied in this study is to eliminate the candidate generation process and minimize the stages of completion. This can be achieved by utilizing the FP-Growth method, which is a more efficient and effective approach to association rule mining.

FP-Growth Method: A More Efficient Approach

The FP-Growth method is a more efficient approach to association rule mining, particularly in large databases. This method starts with the first stage of the Apriori algorithm (K-1 item) and utilizes a tree-like structure to store the frequent items/items. The FP-Growth method has several advantages over the traditional Apriori algorithm, including:

*** Time Efficiency: The completion stage is faster, making it more suitable for large databases. *** Reduction of Frequent Items/Items: FP-Growth produces fewer frequent items/items, making it easier to analyze and understand. *** Results Details: FP-Growth is able to display frequent items/items with a value of <1, which is not displayed by traditional Apriori algorithms.

Advantages of FP-Growth

The use of FP-Growth as a substitute for the candidate generation method in the Apriori algorithm provides several advantages, including:

Improved Efficiency: FP-Growth is more efficient than the traditional Apriori algorithm, particularly in large databases.
Reduced Complexity: FP-Growth produces fewer frequent items/items, making it easier to analyze and understand.
More Detailed Results: FP-Growth is able to display frequent items/items with a value of <1, providing more detailed results.

Applications of FP-Growth

The use of FP-Growth has several applications in various fields, including:

Sales Analysis: FP-Growth can be used to analyze sales data and identify patterns and trends.
Marketing: FP-Growth can be used to analyze customer behavior and preferences, providing insights for marketing strategies.
Recommendation Systems: FP-Growth can be used to develop recommendation systems that suggest products or services based on user behavior and preferences.

Conclusion

In conclusion, the development of a priori algorithm for decision making using FP-Growth provides a more efficient and effective approach to association rule mining. The use of FP-Growth eliminates the candidate generation process and minimizes the stages of completion, making it more suitable for large databases. The advantages of FP-Growth include improved efficiency, reduced complexity, and more detailed results. The applications of FP-Growth are numerous, including sales analysis, marketing, and recommendation systems.
