CxSE: Chest X-ray Slow Encoding CNN forCOVID-19 Diagnosis
This work addresses the problem of rapid COVID-19 detection for medical screening, but it appears incremental as it builds on existing CNN methods for a specific dataset.
The paper tackled COVID-19 diagnosis from chest X-rays by proposing a new CNN architecture called slow Encoding CNN, achieving performance metrics such as a sensitivity of 0.96 for the COVID-19 positive class on a competition test dataset.
The coronavirus continues to disrupt our everyday lives as it spreads at an exponential rate. It needs to be detected quickly in order to quarantine positive patients so as to avoid further spread. This work proposes a new convolutional neural network (CNN) architecture called 'slow Encoding CNN. The proposed model's best performance wrt Sensitivity, Positive Predictive Value (PPV) found to be SP=0.67, PP=0.98, SN=0.96, and PN=0.52 on AI AGAINST COVID19 - Screening X-ray images for COVID-19 Infections competition's test data samples. SP and PP stand for the Sensitivity and PPV of the COVID-19 positive class, while PN and SN stand for the Sensitivity and PPV of the COVID-19 negative class.
