Dual Attentive Sequential Learning for Cross-Domain Click-Through Rate Prediction

1 code implementation5 Jun 2021 Pan Li, Zhichao Jiang, Maofei Que, Yao Hu, Alexander Tuzhilin

While several cross domain sequential recommendation models have been proposed to leverage information from a source domain to improve CTR predictions in a target domain, they did not take into account bidirectional latent relations of user preferences across source-target domain pairs.

Dual Metric Learning for Effective and Efficient Cross-Domain Recommendations

1 code implementation17 Apr 2021 Pan Li, Alexander Tuzhilin

Furthermore, we combine the dual learning method with the metric learning approach, which allows us to significantly reduce the required common user overlap across the two domains and leads to even better cross-domain recommendation performance.
