WebMay 30, 2024 · Transfer learning is a machine learning technique used to improve learning in a new learning model via the transmission of knowledge from another similar already learned model. Transfer learning can dramatically reduce the training time and avoid over-fitting the LDCT restoration model [ 30 ]. WebIn this study, we proposed a novel approach based on transfer learning and deep support vector data description (DSVDD) to distinguish among COVID-19, non-COVID-19 pneumonia, and intact CT images. Our approach consists of three models, each of which can classify one specific category as normal and the other as anomalous.
