摘要:

随着深度学习的巨大成功,其他机器学习范式不得不退居二线。然而,其他模型,特别是基于规则的模型,更具可读性和可解释性,甚至在标记数据不丰富时具有竞争力。然而,现有的大多数基于规则的分类器都存在产生大量分类规则的问题,影响了模型的可读性。这妨碍了分类的准确性,因为噪声规则可能不会为分类添加任何有用的信息,并且还导致更长的分类时间。在这项研究中,我们提出了SigD2,它使用了一种新的,两阶段的修剪策略,修剪了大部分的噪音,冗余和无趣的规则,使分类模型更准确和可读。为了使SigDirect与最流行但不可解释的基于机器学习的分类器(如神经网络和支持向量机)相比更具竞争力,我们建议对SigDirect分类器的集成进行装袋和提升。所提出的算法的结果是相当有前途的,我们能够获得一个最小的统计上显着的分类规则,而不会危及分类精度。我们使用了15个UCI数据集,并将我们的方法与8个现有系统进行了比较。SigD2和提升的SigDirect(ACboost)集成模型不仅在分类精度方面,而且在规则数量方面都优于各种最先进的分类器。

英文摘要:

With the huge success of deep learning, other machine learning paradigms have had to take back seat. Yet other models, particularly rule-based, are more readable and explainable and can even be competitive when labelled data is not abundant. However, most of the existing rule-based classifiers suffer from the production of a large number of classification rules, affecting the model readability. This hampers the classification accuracy as noisy rules might not add any useful informationfor classification and also lead to longer classification time. In this study, we propose SigD2 which uses a novel, two-stage pruning strategy which prunes most of the noisy, redundant and uninteresting rules and makes the classification model more accurate and readable. To make SigDirect more competitive with the most prevalent but uninterpretable machine learning-based classifiers like neural networks and support vector machines, we propose bagging and boosting on the ensemble of the SigDirect classifier. The results of the proposed algorithms are quite promising and we are able to obtain a minimal set of statistically significant rules for classification without jeopardizing the classification accuracy. We use 15 UCI datasets and compare our approach with eight existing systems.The SigD2 and boosted SigDirect (ACboost) ensemble model outperform various state-of-the-art classifiers not only in terms of classification accuracy but also in terms of the number of rules.
