Congress

US Congress bill co-sponsorship hypergraph node classification (2 classes). The primary catalog metric is Accuracy.

US Congress bill co-sponsorship hypergraph node classification (2 classes). The cataloged artifact reports 1 graphs, 2 target classes or tasks.

The release represents higher-order membership with a node-hyperedge incidence relation and supplies node features where available. Some source datasets have no measured features and use documented synthetic features; clique expansion is an alternative representation that discards hyperedge identity.

The catalog records these protocols or variants: Standard split. Evaluation uses Accuracy (higher is better). Exact masks or folds must come from the cited release.

Do not silently replace incidence propagation with clique expansion or merge distinct releases sharing a short name. Random synthetic features, split seeds, hyperedge multiplicity, and isolated-node handling can dominate results and must be reported.
