In this paper, we use two datasets, Aliccp and movieLens. Dataset samples are shown in example/ranking/data.

Real Dataset download methods:

• Aliccp : Dowload address https://tianchi.aliyun.com/dataset/408.
• Movielens : The raw data precess file could be found in Torch-Rechub-ml-1m. You coud direclt dowload precessed file from https://cowtransfer.com/s/5a3ab69ebd314e.

In this repo, we offer the following models, list as follows. And their suructure are shown in the picture.

• Pure MLP as Multi-domain Backbone models.
• MLP + HAMUR
• Pure Wide & Deep as Multi-domain Backbone models.
• Wide & Deep + HUMUR
• Pure DCN as Multi-domain Backbone models.
• DCN + HUMUR
