Abstract

fetched live from OpenAlex

The Coronavirus Disease 2019 (COVID-19) pandemic continues to have a devastating effect on the global population’s health and well-being. Successful screening of infected patients is a crucial step in the battle against COVID-19, with radiology inspection using chest radiography being one of the most popular screening methods. Early studies discovered that patients with COVID-19 infection have anomalies in chest radiography images. In this study, we present our Deep Convolutional Neural Network (CNN) for an automatic detection of COVID-19 using computed tomography (CT). Multiple models are presented and fine-tuned to provide accurate detection of COVID-19 vs. normal vs. pneumonia. The proposed model gives an Area Under Curve (AUC) of 99.64%, an accuracy (ACC) of 96.37%, a specificity of 96.00% and a sensitivity of 97.00%. Moreover, an explainability algorithm has been developed and shows the high efficiency of identifying the pathological signs of COVID-19 in CT scans.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
