Data for modern medical imaging modeling is constrained by their high physical density, complex structure, insufficient annotation, heterogeneity across sites, long-tailed distribution, and sparsely presented information. In this talk, I will cover three of my research to combat these scenarios: the first work focuses on using surrogate medical endpoint to quantify cancer mortality via automated body composition assessment; the second work utilizes deep reinforcement learning to learn better from weakly supervised dental imaging data for a finding summarization; lastly, the third work investigates federated learning settings on how they benefit cross-site collaborative learning and how non-identical and imbalanced data can impact the learning quality in real-world settings. The objective of this talk is to provide a coverage of various methods that more effectively model medical imaging tasks when the available data are constrained.
