Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| combine node attributes with topology (SCI) vs topology-only NMF (SNMF) | NMF community detection · Cornell | AC: 0.3179 -> 0.4769 | Helped |
| SCI vs PCL-DC | attributed community detection · Cora/Citeseer | AC: 0.6525 -> 0.3442 | Hurt |
| SCI vs CESNA | overlapping community detection · WebKB, Cora, Citeseer | F-score: 0.4393 -> 0.5063 | Helped |
| use attribute-derived membership U=SC instead of U directly (ablation) | SCI · synthetic Newman network | AC/NMI | Mixed |
| add node attributes to topology (ablation) | SNMF · synthetic Newman network | AC/NMI | Helped |
| vary sparsity weight alpha (ablation) | SCI · Cornell, Texas | accuracy | Mixed |
| vary topology weight beta (ablation) | SCI · Cornell, Texas | accuracy | No clear effect |
