摘要:

目的:本研究旨在探讨模糊认知图(FCM)在冠心病诊断中的应用,以实现冠心病的自动化、无创性诊断。研究方法:提出了一种计算机辅助诊断模型,用于使用状态空间高级FCM(AFCM)方法对CAD进行可接受的和非侵入性的预测。此外,一个基于规则的机制被纳入,以进一步增加系统的知识和决策机制的可解释性。所提出的方法进行了测试,利用CAD数据集从帕特雷大学的核医学实验室。更具体地说,设计了两种结构的AFCM,并进行了不同的参数测试。此外,所提出的AFCM,这是最近提出的新方程的基础上,与传统的FCM方法进行了比较。结果如下:实验结果表明,与传统方法相比,AFCM方法和新方程的有效性达到了78.21%,分类任务提高了7%(+7%),准确率达到了85.47%。结论:结果表明,AFCM方法在开发模糊认知地图优于传统的方法,而它构成了一个可靠的方法来诊断冠状动脉疾病。结论和未来的研究相关的冠状病毒的大流行提供。

英文摘要:

Purpose: In this study, the recently emerged advances in Fuzzy Cognitive Maps (FCM) are investigated and employed, for achieving the automatic and non-invasive diagnosis of Coronary Artery Disease (CAD). Methods: A Computer-Aided Diagnostic model for the acceptable and non-invasive prediction of CAD using the State Space Advanced FCM (AFCM) approach is proposed. Also, a rule-based mechanism is incorporated, to further increase the knowledge of the system and the interpretability of the decision mechanism. The proposed method is tested utilizing a CAD dataset from the Laboratory of Nuclear Medicine of the University of Patras. More specifically, two architectures of AFCMs are designed, and different parameter testing is performed. Furthermore, the proposed AFCMs, which are based on the new equations proposed recently, are compared with the traditional FCM approach. Results: The experiments highlight the effectiveness of the AFCM approach and the new equations over the traditional approach, which obtained an accuracy of 78.21%, achieving an increase of seven percent (+7%) on the classification task, and obtaining 85.47% accuracy. Conclusions: It is demonstrated that the AFCM approach in developing Fuzzy Cognitive Maps outperforms the conventional approach, while it constitutes a reliable method for the diagnosis of Coronary Artery Disease. Conclusions and future research related to recent pandemic of coronavirus are provided.
