CFAR++: Enhancing Rule Based Classifier
Md Rayhan Kabir, Seeratpal Jaura, Osmar R. Zai͏̈ane · 2023
Over the last few years, associative classifiers have shown massive success in mining patterns using association rules. These rule-based classifiers offer a level of human interpretability, addressing a common concern stemming from several deep learning models. Various associative classifiers have been proposed over the past that have shown state-of-the-art performance. However, those classifiers suffer the limitation of requiring parametric values which vary across different datasets. Furthermore, those frameworks do not consider the statistical significance of the rules. Recently, some works have addressed this limitation by proposing an associative classifier that incorporates the idea of using statistical significance to mine association classification rules. Though the recent associative classifiers show good performance, their performance is greatly affected by the dimension of the data. In this study, we explore the weakness of the recent associative classification models and experiment with using ensemble models to overcome such limitations, particularly on aggregating the ensemble models in a concise but effective predictor. We use 10 UCI datasets for evaluation of our new approach. From our study, we find the results based on the ensemble model with a delayed pruning are very competitive and can better handle large dimensional data spaces.
