Bases: Dataset

A pair of traffic networks synthesized from the Performance Measurement System (PeMS) Data Source. Nodes represent sensors and edges indicate traffic flow correlation. Node attributes are averaged across all time interval. The two networks are noisy permutations of the original network generated by randomly inserting 10% edges (PeMS08-1) and deleting 15% edges (PeMS08-2) from the original network, respectively. There are in total 170 common nodes across two networks.
