Multi-Objective Composite Longitudinal Biomarker Scores for Improved Cancer Risk Assessment
Bitan Sarkar, Ana Maria Kenney, James P. Long +4
Repeated blood-based biomarker measurements can improve cancer risk assessment by capturing longitudinal changes missed by single-time-point analyses. Parametric Empirical Bayes (P…
Bias in Meta-Analytic Modeling of Surrogate Endpoints in Cancer Screening Trials
James P. Long, Abhishikta Roy, Ehsan Irajizad +2
In meta-analytic modeling, the functional relationship between a primary and surrogate endpoint is estimated using summary data from a set of completed clinical trials. Parameters…
Robust Learning on Noisy Graphs via Latent Space Constraints with External Knowledge
Chunhui Gu, Mohammad Sadegh Nasr, James P. Long +2
Graph Neural Networks (GNNs) often struggle with noisy edges. We propose Latent Space Constrained Graph Neural Networks (LSC-GNN) to incorporate external "clean" links and guide em…
A Framework for Mediation Analysis with Multiple Exposures, Multivariate Mediators, and Non-Linear Response Models
James P. Long, Ehsan Irajizad, James D. Doecke +2
Mediation analysis seeks to identify and quantify the paths by which an exposure affects an outcome. Intermediate variables which are effected by the exposure and which effect the…
