摘要:

由SARS-CoV-2引起的COVID-19(2019冠状病毒病)大流行给人类带来了一场危险和毁灭性的灾难。在撰写本文时,没有推荐使用特定的抗病毒药物或疫苗来控制感染传播和扩散。目前COVID-19的诊断是通过逆转录聚合物链反应(RT-PCR)检测完成的。然而,这种方法是昂贵的,耗时的,并不容易在贫困地区。基于咳嗽声音特征和症状元数据设计和开发了可解释的COVID-19诊断AI框架,以克服这些限制。使用包含30000个音频片段的症状和人口统计数据的医疗数据集评估了所提出的框架的性能,其中328个咳嗽声音来自150名患者,具有四种咳嗽类别(COVID-19,哮喘,支气管炎和健康)。实验结果表明,该模型捕获了更好和鲁棒的特征嵌入,以区分COVID-19患者咳嗽和几种类型的非COVID-19咳嗽,具有更高的特异性和准确性,分别为95.04 $\pm$ 0.18%和96.83 $\pm$ 0.18%,同时保持可解释性。

英文摘要:

COVID-19 (coronavirus disease 2019) pandemic caused by SARS-CoV-2 has led to a treacherous and devastating catastrophe for humanity. At the time of writing, no specific antivirus drugs or vaccines are recommended to control infection transmission and spread. The current diagnosis of COVID-19 is done by Reverse-Transcription Polymer Chain Reaction (RT-PCR) testing. However, this method is expensive, time-consuming, and not easily available in straitened regions. An interpretable and COVID-19 diagnosis AI framework is devised and developed based on the cough sounds features and symptoms metadata to overcome these limitations. The proposed framework's performance was evaluated using a medical dataset containing Symptoms and Demographic data of 30000 audio segments, 328 cough sounds from 150 patients with four cough classes ( COVID-19, Asthma, Bronchitis, and Healthy). Experiments' results show that the model captures the better and robust feature embedding to distinguish between COVID-19 patient coughs and several types of non-COVID-19 coughs with higher specificity and accuracy of 95.04 $\pm$ 0.18% and 96.83$\pm$ 0.18% respectively, all the while maintaining interpretability.
