MediEncoder: Nonlinear Representation Learning for High-Dimensional Causal Mediation Analysis
arXiv:2606.30648v1 Announce Type: cross Abstract: Causal mediation analysis decomposes a treatment effect into indirect pathways through mediators and direct pathways not operating through them. Modern biomedical studies often involve high-dimensional covariates and mediators that are noisy proxies for lower-dimensional latent biological processes. Existing methods typically rely on sparsity, linear factor models, or ignore the connection among variables in the learned representations, which can be restrictive when measurements are nonlinear and covariate and mediator factors are structurally
The increasing complexity of modern biomedical data necessitates more sophisticated AI tools for understanding causal relationships, moving beyond previous limitations of linear models and sparsity assumptions.
This development improves the accuracy of causal inference in high-dimensional biological systems, critical for advancing drug discovery, personalized medicine, and understanding complex diseases.
The ability to accurately decompose treatment effects into direct and indirect pathways, even with noisy and nonlinear data, will enhance the interpretability and reliability of AI applications in biomedicine.
