Table 3: Performance of different ablation models.
['Models', 'NLL', 'MAP', 'MRR', 'NDCG']
RQRF-CNN, RQRF-Attention, RQRF-MLP represent RQRF without CNN, attention, and MLP module, respectively. The performances of all ablation models are worse than that of RQRF, which demonstrates the preeminence of RQRF. Specifically, the module that makes the greatest contribution to RQRF is the convolutional layer, without which MAP, MRR, and NDCG drops by 15.9%, 10%, and 23.3%, respectively.
