Mind the Metric: Reproducibility and Fair Benchmarking of Spectral Graph Models for Collaborative Filtering
Domenico de Gioia · Claudio Pomo · Ludovico Boratto · Tommaso Di Noia
摘要
Graph models that manipulate the frequency spectrum of user-item interactions to separate preference signals from noise often report significant improvements, but concerns about evaluation rigor and reproducibility persist. We conduct a reproducibility and replicability study that examines three...
