Jiahao Hu · Wei Zhou · Jie Liao · Junlin Zhu · Junhao Wen · Hongyu Zhang
摘要
Frequency-domain sequential recommendation models enhance sequence representation capacity through spectral transformations. However, existing methods typically adopt coarse-grained spectrum reweighting strategies that strengthen high-frequency components while amplifying random noise within freq...
