OVERVIEW: In collaboration with Clinical Research Informatics (CRI) group within SC CTSI, data scientists from the USC Information Sciences Institute are building innovative data models to characterize COVID-19 disease progression. Deep convolutional neural networks will be applied to x-ray and CT image analysis, as well as prediction of mortality and ventilator needs, with the goal of building diagnostic tools for the disease. ISI’s model mixing strategies have shown success in the past, particularly in environments with heterogeneous data and local capabilities. A recent analysis of blood serum linked to two viral infections identified a set of latent factors that are correlated with different outcomes.
GOALS: The models aim to predict clinical outcomes of COVID-19 patients using machine learning models that learn in a locally distributed manner and can handle longitudinal multivariate data with missing values.
CURRENT STATUS: As of Summer 2020, the machine learning teams are beginning to tailor these methods to relevant COVID-19 datasets, starting with USC's Keck Medical Center with plans to expand to collaborating institutions.
