摘要:

感染COVID-19的患者可能会出现肺炎样症状以及可能损害肺部的呼吸系统问题。根据医学图像,可以使用各种机器学习方法来准确地识别和预测冠状病毒疾病。大多数已发表的机器学习方法可能需要大量的超参数调整,并且不适合小数据集。少样本学习算法通过利用相对小的数据集中的数据,旨在减少对大数据集的需求。这启发我们开发了一个少样本学习模型,用于早期检测COVID-19,以减少这种危险疾病的后效应。所提出的架构结合了少样本学习与预训练的卷积神经网络的集合,从CT扫描图像中提取特征向量进行相似性学习。提出的三重连体网络作为少样本学习模型,将CT扫描图像分为正常、COVID-19和社区获得性肺炎。建议的模型达到了98.719%的总体准确性,99.36%的特异性,98.72%的灵敏度,和ROC评分为99.9%,只有200 CT扫描每个类别的训练数据。

英文摘要:

Patients with the COVID-19 infection may have pneumonia-like symptoms as well as respiratory problems which may harm the lungs. From medical images, coronavirus illness may be accurately identified and predicted using a variety of machine learning methods. Most of the published machine learning methods may need extensive hyperparameter adjustment and are unsuitable for small datasets. By leveraging the data in a comparatively small dataset, few-shot learning algorithms aim to reduce the requirement of large datasets. This inspired us to develop a few-shot learning model for early detection of COVID-19 to reduce the post-effect of this dangerous disease. The proposed architecture combines few-shot learning with an ensemble of pre-trained convolutional neural networks to extract feature vectors from CT scan images for similarity learning. The proposed Triplet Siamese Network as the few-shot learning model classified CT scan images into Normal, COVID-19, and Community-Acquired Pneumonia. The suggested model achieved an overall accuracy of 98.719%, a specificity of 99.36%, a sensitivity of 98.72%, and a ROC score of 99.9% with only 200 CT scans per category for training data.
