论文摘要
自2019年底Covid-19出现以来，Covid-19已成为人工智能（AI）社区的积极研究主题。最有趣的AI主题之一是COVID-19对医学成像的分析。 CT扫描成像是有关该疾病的最有用的工具。这项工作是第二届COV19D竞赛的一部分，在其中设定了两个挑战：COVID-19检测和COVID-19的严重性检测。对于从CT扫描的COVID-19检测，我们提出了具有Densenet-161模型的2D卷积块的集合。在这里，每个具有Densenet-161体系结构的2D卷积块是分别训练的，在测试阶段，集合模型基于其概率的平均值。另一方面，我们提出了一个卷积层的集合，其成立模型用于COVID-19的严重程度检测。除了卷积层外，还使用了三个成立变体，即Inception-V3，Inception-V4和Inception-Resnet。我们提出的方法在第二COV19D竞赛的验证数据中的表现优于基线方法，分别为COVID-19检测和COVID-19的严重性检测分别为11％和16％。
Since the appearance of Covid-19 in late 2019, Covid-19 has become an active research topic for the artificial intelligence (AI) community. One of the most interesting AI topics is Covid-19 analysis of medical imaging. CT-scan imaging is the most informative tool about this disease. This work is part of the 2nd COV19D competition, where two challenges are set: Covid-19 Detection and Covid-19 Severity Detection from the CT-scans. For Covid-19 detection from CT-scans, we proposed an ensemble of 2D Convolution blocks with Densenet-161 models. Here, each 2D convolutional block with Densenet-161 architecture is trained separately and in testing phase, the ensemble model is based on the average of their probabilities. On the other hand, we proposed an ensemble of Convolutional Layers with Inception models for Covid-19 severity detection. In addition to the Convolutional Layers, three Inception variants were used, namely Inception-v3, Inception-v4 and Inception-Resnet. Our proposed approaches outperformed the baseline approach in the validation data of the 2nd COV19D competition by 11% and 16% for Covid-19 detection and Covid-19 severity detection, respectively.
