Multi-Facet Recommender Networks with Spherical Optimization

1 code implementation27 Mar 2021 Yanchao Tan, Carl Yang, Xiangyu Wei, Yun Ma, Xiaolin Zheng

Metric learning has been proposed to capture user-item interactions from implicit feedback, but existing methods only represent users and items in a single metric space, ignoring the fact that users can have multiple preferences and items can have multiple properties, which leads to potential conflicts limiting their performance in recommendation.

Partial Relaxed Optimal Transport for Denoised Recommendation

no code implementations19 Apr 2022 Yanchao Tan, Carl Yang Member, Xiangyu Wei, Ziyue Wu, Xiaolin Zheng

The interaction data used by recommender systems (RSs) inevitably include noises resulting from mistaken or exploratory clicks, especially under implicit feedbacks.

DynStatF: An Efficient Feature Fusion Strategy for LiDAR 3D Object Detection

no code implementations24 May 2023 Yao Rong, Xiangyu Wei, Tianwei Lin, Yueyu Wang, Enkelejda Kasneci

In this work, we propose a novel feature fusion strategy, DynStaF (Dynamic-Static Fusion), which enhances the rich semantic information provided by the multi-frame (dynamic branch) with the accurate location information from the current single-frame (static branch).
