A new technique breaks Dijkstra's 70-year-old record: it finds routes faster in huge networks, changing graph theory forever.

Abstract: This paper investigates the recovery of a node-domain sparse graph signal from the output of a graph filter. This problem, which is often referred to as the identification of the source of a ...

It begins by constructing a fine-grained knowledge graph from the source text，then identifies knowledge gaps in LLMs using the expected calibration error metric ...

Abstract: Feature matching is an essential computer vision task that requires the establishment of high-quality correspondences between two images. Constructing sparse dynamic graphs and extracting ...

Artificial intelligence is getting very good, very fast. Whether it's music, text, code or imagery, the time when it was reliably possible to tell the difference between AI and human outputs is ...
