• W4387521010 abstract "ABSTRACTMachine learning methods have been extensively employed to predict COVID-19 using chest X-ray images in numerous studies. However, a machine learning model must exhibit robustness and provide reliable predictions for diverse populations, beyond those used in its training data, to be truly valuable. Unfortunately, the assessment of model generalisability is frequently overlooked in current literature. In this study, we investigate the generalisability of three classification models – ResNet50v2, MobileNetv2, and Swin Transformer – for predicting COVID-19 using chest X-ray images. We adopt three concurrent approaches for evaluation: the internal-and-external validation procedure, lung region cropping, and image enhancement. The results show that the combined approaches allow deep models to achieve similar internal and external generalisation capability.KEYWORDS: COVID-19X-raymachine learning Disclosure statementNo potential conflict of interest was reported by the author(s).Notes1. https://github.com/dirtmaxim/lungs-finder2. https://keras.io/examples/vision/swin_transformers/3. https://www.kaggle.com/c/rsna-pneumonia-detection-challenge4. https://github.com/agchung/Actualmed-COVID-chestxray-dataset5.
