SOURCE-LINKED INTELLIGENCE

Parallel Training Using a CNN-DNN Architecture for Accelerated Development of Diagnostic Models

arXiv · AI, language, vision and robotics · article · Sep 11, 2026 · UTC

Artificial intelligence has shown promise in assisting radiologists in imaging-based diagnosis across a wide range of diseases. Efficient training of large deep learning models is essential to cope with extremely large data sets or dynamically growing disease data, like in a pandemic like situation. In this retrospective study, we collected 300 CT scans from COVID-19 and non-COVID-19 pneumonia patients from three different centers in Germany. We investigated a hybrid CNN-DNN network model based on image decomposition and localization that naturally supports parallel and efficient training of d
