Graph Neural ODEs with Stability and Conservation Guarantees for Tumor Microenvironment Dynamics (Student Abstract)

Luong Doan, Tien Nguyen, Nhung Duong, Lap Nguyen, Tuan Do

AAAI 2026technical

We present Graph Neural ODEs (GNODEs) for modeling tumor microenvironment dynamics with mathematically guaranteed stability and conservation properties. Unlike bulk ODEs that miss spatial heterogeneity or discrete GNNs that inadequately capture continuous biological processes, GNODEs provide continu

The Fisher Dimension: Instance-Dependent Complexity for Causal Discovery

Luong Doan, Khanh Quoc, Duc Nguyen, Mai Hung, Phong Ho, Nhung Duong +1

ICML 2026poster

Classical sample complexity bounds for causal structure learning are minimax in nature, characterizing worst-case difficulty without distinguishing between easy and hard instances. We study instance-specific complexity for Markov equivalence class (MEC) recovery in linear Gaussian structural equatio…
