Publisher summary· verbatim

arXiv:2505.11552v3 Announce Type: replace-cross Abstract: Graph-based collaborative filtering methods act as low-pass filters in the spectral domain and discard the intermediate-frequency components where community-level user preferences reside. Existing GSP-based methods address the loss through so
