Sharp asymptotics for the Lov\'asz number of random circulant graphs

We study the LOV\'ASZ number of dense random circulant graphs generated by independent Bernoulli bits indexed by cyclic distances. Although only $O(n)$ independent random inputs determine $O(n^2)$ globally dependent edge indicators, we prove sharp expectation asymptotics along all odd orders, including composite orders...

SkySense-VITA: Towards Universal In-context Segmentation of Multi-modal Remote Sensing Imagery

SkySense-VITA is introduced, a unified in-context segmentation model, which synergistically processes both optical and Synthetic Aperture Radar (SAR) imagery using VI sual, T extu A l, or fused prompts, and is proposed to de-couple multi-modal prompt fusion and prediction process.
