HSG-12M: A Large-Scale Benchmark of Spatial Multigraphs from the Energy Spectra of Non-Hermitian Crystals

This paper introduces Poly2Graph, an automated pipeline for generating HSG-12M, a pioneering 16.7-million-scale dataset of spatial multigraphs derived from non-Hermitian crystal energy spectra, which bridges condensed matter physics and geometry-aware graph learning by preserving vital geometric information often discarded in existing benchmarks.

Distant Object Localisation from Noisy Image Segmentation Sequences

This paper proposes a reliable, computation-efficient system for 3D localisation of distant objects in safety-critical surveillance tasks like wildfire monitoring by applying multi-view triangulation or particle filters to noisy image segmentation sequences from drones, offering shape and uncertainty estimates without requiring specialised sensors or full 3D reconstruction.
