5-class node classification Wikipedia Squirrel page node classification (5 classes, heterophilic). Uses the Geom-GCN/PyG node features and graph. Evaluated by Accuracy.
Dataset details
Task
Wikipedia Squirrel page node classification (5 classes, heterophilic). The primary catalog metric is Accuracy.
Data
Wikipedia Squirrel page node classification (5 classes, heterophilic). The cataloged artifact reports 1 graphs, 5 target classes or tasks.
Features
Features and edges follow the Geom-GCN/PyG artifact: WebKB uses webpage bag-of-words and hyperlinks, Actor uses film-page keywords and co-occurrence links, and WikipediaNetwork uses page features and hyperlinks.
Splits and evaluation
The catalog records these protocols or variants: Standard split, Filtered split. Evaluation uses Accuracy (higher is better). Exact masks or folds must come from the cited release.
Quirks and pitfalls
These small or repurposed graphs have contested preprocessing and split conventions. Results across Geom-GCN, PyG, and corrected heterophily artifacts are not automatically comparable; class imbalance and high variance require multiple splits.
Sources
Geom-GCN 10 fixed splits.
