Recommender system, which is more important, pay-AUC or click-AUC?

22 May 2024 1 4K Report

For example, if offline click-AUC improves from 0.77 to 0.82 VS pay-AUC improves from 0.88 to 0.91, which online gain will be greater?

Tong Guo

It depends on the weighted fusion formulas for predict-ctr and predict-cxr.

If the online items are sorted by predict-ctr, then click-auc matters.

If the online items are sorted by predict-cxr, then pay-auc matters.
