Ryan Baker is a Professor at the University of Pennsylvania, and Director of the Penn Center for Learning Analytics. His lab conducts research on engagement and robust learning within online and blended learning, seeking to find actionable indicators that can be used today but which predict future student outcomes. Baker has developed models that can automatically detect student engagement in over a dozen online learning environments, and has led the development of an observational protocol and app for field observation of student engagement that has been used by over 150 researchers in 7 countries. Predictive analytics models he helped develop have been used to benefit over a million students, over a hundred thousand people have taken MOOCs he ran, and he has coordinated longitudinal studies that spanned over a decade. He was the founding president of the International Educational Data Mining Society, is currently serving as Editor of the journal Computer-Based Learning in Context, is Associate Editor of the Journal of Educational Data Mining, was the first technical director of the Pittsburgh Science of Learning Center DataShop, and currently serves as Co-Director of the MOOC Replication Framework (MORF). Baker has co-authored published papers with over 300 colleagues.

Abstract：COVID-19 is a pandemic disease that caused more than 6.84 million deaths until 7/Feb/2023. X-ray and CT scans are two popular chest imaging techniques used in radiology to get detailed images of the chest noninvasively for diagnostic purposes. Traditional manual analysis of X-ray or CT-based scans is tedious and error-prone. To solve the problem, our lab develops and applies novel big-data-based machine learning theories and techniques, such as advanced pooling-based networks, graph convolutional networks, attention neural networks, weakly supervised networks, etc. We also use cloud computing techniques to run our developed app on the remote server to help doctors in the suburban area. Two other chest-related infectious diseases: secondary pulmonary tuberculosis and community-acquired pneumonia, will be covered in this talk.
