A Survey on Cross-Domain Sequential Recommendation

no code implementations10 Jan 2024 Shu Chen, Zitao Xu, Weike Pan, Qiang Yang, Zhong Ming

Cross-domain sequential recommendation (CDSR) shifts the modeling of user preferences from flat to stereoscopic by integrating and learning interaction information from multiple domains at different granularities (ranging from inter-sequence to intra-sequence and from single-domain to cross-domain).

Siamese Representation Learning for Unsupervised Relation Extraction

1 code implementation1 Oct 2023 Guangxin Zhang, Shu Chen

Unsupervised relation extraction (URE) aims at discovering underlying relations between named entity pairs from open-domain plain text without prior information on relational distribution.

Improving Neural Radiance Fields with Depth-aware Optimization for Novel View Synthesis

1 code implementation11 Apr 2023 Shu Chen, Junyao Li, Yang Zhang, Beiji Zou

Through these explicit constraints and the implicit constraint from NeRF, our method improves the view synthesis as well as the 3D-scene geometry performance of NeRF at the same time.

Structure-Aware NeRF without Posed Camera via Epipolar Constraint

1 code implementation1 Oct 2022 Shu Chen, Yang Zhang, Yaxin Xu, Beiji Zou

This two-stage strategy is not convenient to use and degrades the performance because the error in the pose extraction can propagate to the view synthesis.

Estimation of 3D Human Pose Using Prior Knowledge

no code implementations9 May 2021 Shu Chen, Lei Zhang, Beiji Zou

Estimating three-dimensional human poses from the positions of two-dimensional joints has shown promising results. However, using two-dimensional joint coordinates as input loses more information than image-based approaches and results in ambiguity. In order to overcome this problem, we combine bone length and camera parameters with two-dimensional joint coordinates for input. This combination is more discriminative than the two-dimensional joint coordinates in that it can improve the accuracy of the model's prediction depth and alleviate the ambiguity that comes from projecting three-dimensional coordinates into two-dimensional space.

Dynamical evolution in a one-dimensional incommensurate lattice with $\mathcal{PT}$ symmetry

no code implementations14 Jan 2021 Zhihao Xu, Shu Chen

We investigate the dynamical evolution of a parity-time ($\mathcal{PT}$) symmetric extension of the Aubry-Andr\'{e} (AA) model, which exhibits the coincidence of a localization-delocalization transition point with a $\mathcal{PT}$ symmetry breaking point.
