A Quantum Encoding of Traveling Salesperson Tours via Route Generation, Cost Phases, and a Reversible Valid-Permutation Oracle

Alexander Johannes Stasik, Franz Georg Fuchs

For a traveling salesperson problem (TSP) of n cities, we present a compact quantum encoding based on a time-register representation of tours. A candidate route is represented as a…

Learning partially observed systems with neural Hamiltonian ordinary differential equations

Sunniva Meltzer, Sølve Eidnes, Alexander Johannes Stasik

When learning dynamical systems from data, embedding physical structure can constrain the solution space and improve generalization, but many physics-informed models assume access…

Unreliable Uncertainty Estimates with Monte Carlo Dropout

Aslak Djupskås, Alexander Johannes Stasik, Signe Riemer-Sørensen

Reliable uncertainty estimation is crucial for machine learning models, especially in safety-critical domains. While exact Bayesian inference offers a principled approach, it is of…
