Fast Algorithms for Mining Association Rules
📜 Abstract
We are interested in mining association rules in large databases of sales transactions. We present two new algorithms for solving this problem that are fundamentally different from the known algorithms. Experiments with synthetic as well as real-life data show that these algorithms outperform the known algorithms by factors ranging from three to over an order of magnitude. We also show how the best features of the two proposed algorithms can be combined into a hybrid algorithm, called Apriori. The basic idea in these algorithms is the use of novel data structures and techniques to count itemsets. We also talk about how the performance of the algorithms can be further improved by incorporating buffer management and other low-level implementations. Based on our performance evaluations, we recommend the use of the hybrid algorithm over the known ones.
✨ Summary
The paper, “Fast Algorithms for Mining Association Rules,” presents two new algorithms to improve the process of mining association rules in large datasets, specifically sales transactions. This research directly addresses efficiency issues found in previous algorithms. Consistent with empirical results, the proposed algorithms significantly outperform existing algorithms, with improvements ranging from threefold to over an order of magnitude. A hybrid algorithm, named Apriori, combines the best features of both individual algorithms.
This paper has had significant influence in the field of data mining, especially in market basket analysis and related applications. The introduction of the Apriori algorithm, in particular, set a new standard for mining frequent itemsets and has been widely cited in subsequent literature as the foundational algorithm for association rule learning. Its impact continues to be felt in various domains that require pattern recognition within large datasets.
