In this paper, we propose an innovative iterative approach to rule learning, specifically designed for (though not limited to) text-based data. Our method focuses on progressively expanding the vocabulary used in each iteration, resulting a significant reduction memory consumption. Additionally, introduce Value of Confidence, which quantifies reliability generated rules. By leveraging our ensures that only most robust and trustworthy rules are retained, thereby enhancing overall quality...
