Talk
Fusion of Multi-modal Data for Clinical Event Prediction
Even though advancements in deep learning techniques carry the potential to make significant contributions to healthcare, most of current models consider only a single input data stream without incorporating data that can inform clinical context. Yet in practice, non-imaging data based on the clinical history and laboratory data enable physicians to interpret imaging findings in the appropriate clinical context, leading to a higher diagnostic accuracy. Models must also achieve the capability to process contextual clinical data in addition to pixel or other sensor data. This talk will present multiple fusion machine learning methodologies including graph-based models, with boosted performance by integrating the clinical context with the imaging data applied to different clinical context.

Artificial Neural Networks for Understanding Human Brains
Artificial neural networks (ANNs), including deep learning, were originally inspired by biological neural networks. In turn, ANNs are now being used to study the human brain. We show that deep learning of fMRI can map the brain’s hierarchical functional organization by detecting “meta-networks” that represent interactions of low-order intrinsic connectivity networks.
