The Center for Generative AI is excited to launch the Fall 2024 AI Health Invited Talk Series. The seminars will take place on Thursdays at 12pm at Dell Medical School and will consist of a 30 minute hybrid Zoom talk followed by a 30 minute in-person lunch discussion (lunch will be provided).

 

The goal of the lunch discussion is to connect computer scientists and engineers with clinicians to tackle actionable AI/Health projects. We ask that you kindly fill out the RSVP form if you are interested in attending the in-person lunch discussion. While the talk is open to everyone, due to limited space the in-person lunch will be provided to those who RSVP under a first-come, first-serve basis until we reach capacity.

 

RSVP here to attend in person.

This Week's Speaker: Tianlong Chen, Assistant Professor, The University of North Carolina at Chapel Hill

 

Title: Flexible Modality Learning: Modeling Arbitrary Modality Combination via the Mixture-of-Experts Framework

 

Abstract: While multimodal approaches are essential in understanding biological and disease behaviors, existing works primarily focus on single modalities such as imaging, genomics, or clinical data. Few recent studies attempt to integrate multiple modalities, and the lack of robust methods to handle missing modalities often limits the usability of such integrative approaches, forcing reliance on samples where the target modalities are available. Addressing this gap, we propose a novel multimodal learning framework, Flex-MoE (Flexible Mixture-of-Experts), which is flexible in incorporating diverse modalities in healthcare research while being resilient to missing modality scenarios through an advanced Sparse MoE design. This talk will illustrate the core idea of Flex-MoE, and demonstrate its effectiveness in handling diverse missing modality scenarios.
