# Correlated Utility-based Pattern Mining

## TL;DR

This paper introduces CoUPM, an efficient method for mining high-utility, positively correlated patterns in data, addressing limitations of previous utility-oriented mining by considering item correlation for more insightful results.

## Contribution

The paper proposes a novel utility mining approach that incorporates item correlation, improving pattern relevance and computational efficiency over existing methods.

## Key findings

- CoUPM outperforms state-of-the-art algorithms in efficiency.
- Patterns mined are more insightful due to correlation consideration.
- Experimental results confirm higher effectiveness of correlated high-utility patterns.

## Abstract

In the field of data mining and analytics, the utility theory from Economic can bring benefits in many real-life applications. In recent decade, a new research field called utility-oriented mining has already attracted great attention. Previous studies have, however, the limitation that they rarely consider the inherent correlation of items among patterns. Consider the purchase behaviors of consumer, a high-utility group of products (w.r.t. multi-products) may contain several very high-utility products with some low-utility products. However, it is considered as a valuable pattern even if this behavior/pattern may be not highly correlated, or even happen by chance. In this paper, in light of these challenges, we propose an efficient utility mining approach namely non-redundant Correlated high-Utility Pattern Miner (CoUPM) by taking positive correlation and profitable value into account. The derived patterns with high utility and strong positive correlation can lead to more insightful availability than those patterns only have high profitable values. The utility-list structure is revised and applied to store necessary information of both correlation and utility. Several pruning strategies are further developed to improve the efficiency for discovering the desired patterns. Experimental results show that the non-redundant correlated high-utility patterns have more effectiveness than some other kinds of interesting patterns. Moreover, efficiency of the proposed CoUPM algorithm significantly outperforms the state-of-the-art algorithm.
