- Abstract summary: We propose a robust CNN-based network, called CVR-Net, for the automatic recognition of the coronavirus from CT or X-ray images.
We train and test the proposed CVR-Net on three different datasets, where the images have collected from different open-source repositories.
Our model achieves an overall F1-score & accuracy of 0.997 & 0.998; 0.963 & 0.964; 0.816 & 0.820; 0.961 & 0.961; and 0.780 & 0.780, respectively, for task-1 to task-5.

- Abstract: The novel Coronavirus Disease 2019 (COVID-19) is a global pandemic disease
spreading rapidly around the world. A robust and automatic early recognition of
COVID-19, via auxiliary computer-aided diagnostic tools, is essential for
disease cure and control. The chest radiography images, such as Computed
Tomography (CT) and X-ray, and deep Convolutional Neural Networks (CNNs), can
be a significant and useful material for designing such tools. However,
designing such an automated tool is challenging as a massive number of manually
annotated datasets are not publicly available yet, which is the core
requirement of supervised learning systems. In this article, we propose a
robust CNN-based network, called CVR-Net (Coronavirus Recognition Network), for
the automatic recognition of the coronavirus from CT or X-ray images. The
proposed end-to-end CVR-Net is a multi-scale-multi-encoder ensemble model,
where we have aggregated the outputs from two different encoders and their
different scales to obtain the final prediction probability. We train and test
the proposed CVR-Net on three different datasets, where the images have
collected from different open-source repositories. We compare our proposed
CVR-Net with state-of-the-art methods, which are trained and tested on the same
datasets. We split three datasets into five different tasks, where each task
has a different number of classes, to evaluate the multi-tasking CVR-Net. Our
model achieves an overall F1-score & accuracy of 0.997 & 0.998; 0.963 & 0.964;
0.816 & 0.820; 0.961 & 0.961; and 0.780 & 0.780, respectively, for task-1 to
task-5. As the CVR-Net provides promising results on the small datasets, it can
be an auspicious computer-aided diagnostic tool for the diagnosis of
coronavirus to assist the clinical practitioners and radiologists. Our source
codes and model are publicly available at

Convolutional Neural Networks (CNN) have seen success in identifying pathologies in Chest X-Ray (CXR) images.
In this work, we analyze the utility of pretraining on unlabeled ImageNet or CXR datasets using various algorithms and in multiple settings.
Some findings of our work include: (i) supervised training with labeled ImageNet learns strong representations that are hard to beat; (ii) self-supervised pretraining on ImageNet (1M images) shows performance similar to self-supervised pretraining on a CXR dataset (100K images); and (iii) the CNN trained on supervised

Vision Transformers (ViTs) have not been applied to this task despite their high classification performance on generic images.
ViTs do not rely on convolutions but on patch-based self-attention and in contrast to CNNs, no prior knowledge of local connectivity is present.
Our results show that while the performance between ViTs and CNNs is on par with a small benefit for ViTs, DeiTs outperform the former if a reasonably large data set is available for training.
