Therefore, automatic and accurate detection of COVID-19 using medical imaging modalities, which are more widely available and accessible, can be beneficial as an alternative diagnostic tool. In this study, an\n                    <jats:bold>Artificial Intelligence model for Detection of COVID-19 (AIDCOV)<\/jats:bold>\n                    is developed to classify chest radiography images as belonging to a person with either COVID-19, other infections, or no pneumonia (i.e., normal). The hierarchical structure in AIDCOV captures the dependencies among features and improves model performance while an attention mechanism makes the model interpretable and transparent. We used several publicly available datasets of both\n                    <jats:bold>computed tomography (CT)<\/jats:bold>\n                    and X-ray modalities. The main public dataset for chest X-ray images contains 475 COVID-19 samples, 3949 samples from other viral\/bacterial infections, and 1583 normal samples. Our model achieves a mean cross-validation accuracy of 98.4%. AIDCOV has a sensitivity of 99.8%, a specificity of 100%, and an F1-score of 99.8% in detecting COVID-19 from X-ray images on that dataset. Using a large dataset of CT images, our model obtained mean cross-validation accuracy and sensitivity of 98.8% and 99.4%, respectively. Additionally, our interpretable model can distinguish subtle signs of infection within each radiography image. Assuming these results hold up in larger datasets obtained from a variety of patients over the world, AIDCOV can be used in conjunction with or instead of RT-PCR testing (where RT-PCR testing is unavailable) to detect and isolate individuals with COVID-19, prevent onward transmission to the general population and healthcare workers, and highlight the areas in the lungs that show signs of COVID-related damage.\n                  <\/jats:p>","DOI":"10.1145\/3466690","type":"journal-article","created":{"date-parts":[[2021,10,22]],"date-time":"2021-10-22T18:24:54Z","timestamp":1634927094000},"page":"1-20","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":19,"title":["AIDCOV: An Interpretable Artificial Intelligence Model for Detection of COVID-19 from Chest Radiography Images"],"prefix":"10.1145","volume":"12","author":[{"given":"Maryam","family":"Zokaeinikoo","sequence":"first","affiliation":[{"name":"Department of Supply Chain &amp; Information Systems, Smeal College of Business, The Pennsylvania State University, State College, University Park, PA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pooyan","family":"Kazemian","sequence":"additional","affiliation":[{"name":"Department of Operations, Weatherhead School of Management, Case Western Reserve University, Cleveland, OH"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Prasenjit","family":"Mitra","sequence":"additional","affiliation":[{"name":"College of Information Sciences and Technology, The Pennsylvania State University, State College, University Park, PA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Soundar","family":"Kumara","sequence":"additional","affiliation":[{"name":"Department of Industrial and Manufacturing Engineering, The Pennsylvania State University, State College, University Park, PA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2021,10,22]]},"reference":[{"key":"e_1_2_1_1_1","volume-title":"https:\/\/promedmail.org\/promed-post\/ (accessed","year":"2021","unstructured":"Promed Post. 2021.
