摘要:

边缘计算是医疗保健领域快速发展且急需的技术。在边缘设备上实现人工智能的问题是最已知的神经网络数据分析方法和算法的复杂性和高资源强度。在低功耗微控制器上实现这些方法的难度要求为神经网络开发新的有效算法。本文提出了一种基于LogNNet神经网络的医学数据分析方法,该方法利用混沌映射来转换输入信息。该方法有效地解决了分类问题,并根据一组医疗健康指标计算患者疾病存在的风险因素。LogNNet在评估围产期风险方面的效率在从UC Irvine机器学习库获得的心脏分娩图数据上得到了说明。分类精度达到~91%,Arduino微控制器上使用的RAM为~3-10 kB。使用在以色列卫生部公开数据库上训练的LogNNet网络,提供COVID-19快速检测的服务概念。分类精度达到~95%,使用~0.6 kB的RAM。在所有示例中,使用标准分类质量指标(精度、召回率和F1-measure)对模型进行测试。LogNNet架构允许在低RAM资源的物联网医疗外设上实现人工智能,可用于临床决策支持系统。

英文摘要:

Edge computing is a fast-growing and much needed technology in healthcare. The problem of implementing artificial intelligence on edge devices is the complexity and high resource intensity of the most known neural network data analysis methods and algorithms. The difficulty of implementing these methods on low-power microcontrollers with small memory size calls for the development of new effective algorithms for neural networks. This study presents a new method for analyzing medical data based on the LogNNet neural network, which uses chaotic mappings to transform input information. The method effectively solves classification problems and calculates risk factors for the presence of a disease in a patient according to a set of medical health indicators. The efficiency of LogNNet in assessing perinatal risk is illustrated on cardiotocogram data obtained from the UC Irvine machine learning repository. The classification accuracy reaches ~91% with the ~3-10 kB of RAM used on the Arduino microcontroller. Using the LogNNet network trained on a publicly available database of the Israeli Ministry of Health, a service concept for COVID-19 express testing is provided. A classification accuracy of ~95% is achieved, and ~0.6 kB of RAM is used. In all examples, the model is tested using standard classification quality metrics: precision, recall, and F1-measure. The LogNNet architecture allows the implementation of artificial intelligence on medical peripherals of the Internet of Things with low RAM resources and can be used in clinical decision support systems.
