However, far less attention has been paid to the overfitting problem of models in recommendation systems, which, on the contrary, is recognized as a critical issue for deep neural networks.
To address this issue, we propose an approach that can Jointly optimize the Ranking and Calibration abilities (JRC for short).
If conversion happens outside the waiting window, this sample will be duplicated and ingested into the training pipeline with a positive label.
Concretely, STAR has the star topology, which consists of the shared centered parameters and domain-specific parameters.

For example, a simple attempt to learn the combination of feature A and feature B <A, B> as the explicit cartesian product representation of new features can outperform previous implicit feature interaction models including factorization machine (FM)-based models and their variations.
