Tensor Completion via Leverage Sampling and Tensor QR Decomposition for Network Latency Estimation

no code implementations27 Jun 2023 Jun Lei, Ji-Qian Zhao, Jing-Qi Wang, An-Bao Xu

The main idea of our method is improving the tensor leverage sampling strategy and introduce tensor QR decomposition into tensor completion.

Hybrid CNN Based Attention with Category Prior for User Image Behavior Modeling

no code implementations5 May 2022 Xin Chen, Qingtao Tang, Ke Hu, Yue Xu, Shihang Qiu, Jia Cheng, Jun Lei

In Meituan, one of the largest e-commerce platform in China, an item is typically displayed with its image and whether a user clicks the item or not is usually influenced by its image, which implies that user's image behaviors are helpful for understanding user's visual preference and improving the accuracy of CTR prediction.

Continual Learning for CTR Prediction: A Hybrid Approach

no code implementations18 Jan 2022 Ke Hu, Yi Qi, Jianqiang Huang, Jia Cheng, Jun Lei

To address this problem, we formulate CTR prediction as a continual learning task and propose COLF, a hybrid COntinual Learning Framework for CTR prediction, which has a memory-based modular architecture that is designed to adapt, learn and give predictions continuously when faced with non-stationary drifting click data streams.
