An open-sourced dataset, which contains 349 COVID-19 CT images from 216 patients and 463 non-COVID- 19 CTs, is built, which is used to develop diagnosis methods based on multi-task learning and self-supervised learning that achieve an F1 of 0.90, an AUC of0.98, and an accuracy of 1.89.
COVID-Net is introduced, a deep convolutional neural network design tailored for the detection of COVID-19 cases from chest X-ray (CXR) images that is open source and available to the general public, and COVIDx, an open access benchmark dataset comprising of 13,975 CXR images across 13,870 patient patient cases.
It is deduced that several testing protocols for the recognition are not fair and that the neural networks are learning patterns in the dataset that are not correlated to the presence of COVID-19.
The results show that even a simple binary machine learning classifier is able to classify correctly healthy and COVID-19 sounds, and opens the door to further investigation of how automatically analysed respiratory patterns could be used as pre-screening signals to aid CO VID-19 diagnosis.
Experimental results show that the proposed patch-based convolutional neural network approach achieves state-of-the-art performance and provides clinically interpretable saliency maps, which are useful for COVID-19 diagnosis and patient triage.
The state-of-the-art performances achieved show that, with the help of artificial intelligence, chest X-rays can become a cheap and accurate auxiliary method for COVID-19 diagnosis and indicate an analytical path for future research on diagnosis.
Five different deep learning models and their ensemble and their ensemble and their ensemble and their ensemble and their ensemble have been used to classify COVID-19, pneumoniæ and healthy subjects using chest X-ray images, showing that the ResNets were the most interpretable models.
Results based on a dataset of X-ray images show that COVID-CAPS has advantage over previous CNN-based models, being capable of handling small datasets, which is of significant importance due to sudden and rapid emergence of CO VID-19.
A high-speed and accurate fully-automated method to detect COVID-19 from the patient's chest CT scan images is proposed and a novel architecture for improving the classification accuracy of convolutional networks on images containing small important objects is introduced.
Adding a benchmark result helps the community track progress.
