q2 · i? · design · r2

Benchmark comparison on three datasets (MOOC, LectureBank, UCD) against general-purpose and task-specific baselines; Table 1 reports ProPRL best on all nine combinations, with the largest relative AUC gain of 6.11% on UCD and improvements "from 1.96% to 6.11%".

"ProPRL nev- ertheless outperforms the strongest baseline in every com- parison, demonstrating a consistent performance advantage across different evaluation settings."

Discussion¶

Related Claims¶

• Removing any ProPRL component reduces F1 on all three datasets, with multi-hop propagation having the largest overall impact — related
• ProPRL incurs moderate overhead over DGCPL but remains lightweight, using under 40 MB GPU memory and under 0.18 seconds test-time inference — related
• ProPRL is sensitive to learning rate but comparatively insensitive to its structural hyperparameters, with propagation depth around 5 capturing most multi-hop benefit — related
