1 Parameter-Efficient Transfer from Sequential Behaviors for User Modeling and Recommendation SIGIR2020 https://arxiv.org/abs/2001.04253

With github codes and datasets: https://github.com/fajieyuan/SIGIR2020_peterrec

Keywords: self-supervised learning, user sequential behaviors, pretraining, transfer learning, universal user representation, user profile prediction, cold-start problem

(1) We are the first to evidence that self-supervised user behavior pre-training helps many downstream tasks.

(2) We are also the first to provide user profile prediction as a way to assess the universal or generic property of user representation

(3) We release a large-scale public dataset for user representation transer learning and source code.

2 One Person, One Model, One World: Learning Continual User Representation without Forgetting SIGIR2021 https://arxiv.org/abs/2009.13724

With github codes and datasets: https://github.com/fajieyuan/SIGIR2021_Conure

Keywords: self-supervised learning, lifelong learning, pre-training, transfer learning, fine-tuning, general-purpose user representation, user profile prediction, cold-start recommendation

(1) We are the first to propose universal lifelong user representation learning mechanism for recommender system

(2) We are the first to clearly demonstrate the catastrophic forgetting and over-parameterization issues in recommender sytem.

(3) We release the dataset for lifelong user representation learning and source code.
