Abstract: Artificial intelligence continues to permeate healthcare but has been met with mixed success. While the digitization of the patient has led to important discoveries, these data have their own limitations and biases which restrict the utility of the machine learning models that are built on them. The utilization of multiple modalities of digital patient data in modeling can alleviate some of these issues but their discrepant structure make effective fusion challenging. This talk will highlight opportunities and challenges of creating multi-modal machine learning models in multiple clinical domains. To showcase the power of these approaches, projects from two recent publications will be highlighted that target clinical questions from different angles. The first project highlights how deep neural networks using a massive corpus of Electronic Health Records (EHR) and raw electrocardiogram (ECG) waveform data can be used to more quickly detect clinically-relevant heart failure conditions that often require extensive follow-up. In the second, deep fusion models of EHR and ECG data are used to increase screening specificity for pulmonary embolism for moderate-to-high suspicion individuals. This work hints at the possibility of reducing testing burden for a disease that is hard to accurately screen. Finally, recent work leveraging federated learning approaches will be highlighted as ways to overcome potential health system-specific biases and create more robust, generalizable models for more personalized medicine.
