The COVID-19 pandemic continues to wreak havoc on the world's population's health and well-being. Successful screening of infected patients is a critical step in the fight against it, with radiology examination using chest radiography being one of the most important screening methods. For the definitive diagnosis of COVID-19 disease, reverse-transcriptase polymerase chain reaction remains the gold standard. Currently available lab tests may not be able to detect all infected individuals; new screening methods are required. We propose a Multi-Input Transfer Learning COVID-Net fuzzy convolutional neural network to detect COVID-19 instances from torso X-ray, motivated by the latter and the open-source efforts in this research area. Furthermore, we use an explainability method to investigate several Convolutional Networks COVID-Net forecasts in an effort to not only gain deeper insights into critical factors associated with COVID-19 instances, but also to aid clinicians in improving screening. We show that using transfer learning and pre-trained models, we can detect it with a high degree of accuracy. Using X-ray images, we chose four neural networks to predict its probability. Finally, in order to achieve better results, we considered various methods to verify the techniques proposed here. As a result, we were able to create a model with an AUC of 1.0 and accuracy, precision, and recall of 0.97. The model was quantized for use in Internet of Things devices and maintained a 0.95 percent accuracy.
新冠疫情持续对全球人口的健康与福祉造成严重破坏。成功筛查感染患者是抗击疫情的关键一步,胸部X光放射学检查是最重要的筛查方法之一。对于新冠疾病的确诊,逆转录聚合酶链反应仍是金标准。目前可用的实验室检测可能无法检测出所有感染者,因此需要新的筛查方法。受此启发以及该研究领域的开源成果影响,我们提出了一种多输入迁移学习新冠网络模糊卷积神经网络,用于从躯干X光中检测新冠病例。此外,我们使用一种可解释性方法来研究几种卷积网络新冠网络的预测结果,不仅是为了更深入地了解与新冠病例相关的关键因素,也是为了帮助临床医生改进筛查工作。我们表明,通过迁移学习和预训练模型,能够高精度地检测出新冠病例。利用X光图像,我们选择了四个神经网络来预测其概率。最后,为了取得更好的结果,我们考虑了各种方法来验证此处提出的技术。结果,我们创建了一个AUC为1.0、准确率、精确率和召回率均为0.97的模型。该模型经过量化后可用于物联网设备,且准确率保持在95%。
