EMRes-50 model . Detection of lung cancer on chest ct images using minimum redundancy maximum relevance feature selection method with convolutional neural networks. For the image features that led to categorization, there were varied levels of agreement in the interobserver and intraobserver components that . So, based on this motivation, we apply MPA as a feature selector from deep features that produced from CNN (largely redundant), which, accordingly minimize capacity and resources consumption and can improve the classification of COVID-19 X-ray images. A combination of fractional-order and marine predators algorithm (FO-MPA) is considered an integration among a robust tool in mathematics named fractional-order calculus (FO). Our dataset consisting of 60 chest CT images of COVID-19 and non-COVID-19 patients was pre-processed and segmented using a hybrid watershed and fuzzy c-means algorithm. A. Comparison with other previous works using accuracy measure. Chexnet: Radiologist-level pneumonia detection on chest x-rays with deep learning. arXiv preprint arXiv:2003.11597 (2020). The conference was held virtually due to the COVID-19 pandemic. Therefore, in this paper, we propose a hybrid classification approach of COVID-19.
