ShapKO: Shapley-Adaptive Modality Knockout for Robust Multimodal Learning

Nusrat Binta Nizam, Fengbei Liu, Sunwoo Kwak +3

Multimodal medical models often degrade when inputs are missing, a common scenario in real-world clinical workflows. Separately, even when all modalities are present, modality domi…

MAdam: Metric-Aware Multi-Objective Adam

Fengbei Liu, Rachit Saluja, Sunwoo Kwak +5

Multi-objective optimization (MOO) underlies many machine learning problems, yet MOO solvers across the loss-balancing, gradient-balancing, and Pareto-based families almost univers…

Network-Aware Bilinear Tokenization for Brain Functional Connectivity Representation Learning

Leo Milecki, Qingyu Hu, Bahram Jafrasteh +2

Masked autoencoders (MAEs) have recently shown promise for self-supervised representation learning of resting-state brain functional connectivity (FC). However, a fundamental quest…

Prediction of Rectal Cancer Regrowth from Longitudinal Endoscopy

Jorge Tapias Gomez, Despoina Kanata, Aneesh Rangnekar +8

Clinical trial studies indicate benefit of watch-and-wait (WW) surveillance for patients with rectal cancer showing a complete or near clinical response (CR) directly after treatme…
