Jákup Svøðstein

Researcher at the University of the Faroe Islands. I survey, benchmark, and build ML systems for weather, maritime, and logistics, with GNN architecture expertise as the theoretical backbone.

My work consistently shows that data quality, evaluation design, and design-space understanding drive performance more than model complexity.

What I work on

  • Graph neural networks for physical simulation — design-space analysis of GNN architectures for fluid simulation (manuscript in preparation)
  • Diagnostic weather benchmarking — conditional evaluation protocols that expose failure modes aggregate metrics hide, over complex maritime terrain (manuscript in preparation)
  • Maritime data science — AIS vessel classification, adaptive transmission power, public datasets with RF metadata
  • Logistics ML — GATv2 spatio-temporal encoders, transfer learning as integration middleware for low-data regimes

Projects

Project Description
AIS Vessel Classification 174-configuration factorial experiment showing preprocessing explains 58% of performance variance (ICOIN 2026)
AIS-TSH Dataset 7.8M AIS messages with per-message RF metadata (IEEE DataPort, DOI: 10.21227/fjhz-qf06)
Logistics Transfer Learning GATv2 encoder with transfer learning for supply-chain graphs: 30–41% improvement, 4–10× data reduction (CITA 2026)
Adaptive AIS Transmission Power Analytic collision-likelihood model: 35–64% collision reduction, 38–70% energy savings (ICSCCT 2026)
