CPMR: Context-Aware Incremental Sequential Recommendation with Pseudo-Multi-Task Learning

1 code implementation9 Sep 2023 Qingtian Bian, Jiaxing Xu, Hui Fang, Yiping Ke

To dually improve the performance of temporal states evolution and incremental recommendation, we design a Pseudo-Multi-Task Learning (PMTL) paradigm by stacking the incremental single-target recommendations into one multi-target task for joint optimization.

Union Subgraph Neural Networks

1 code implementation25 May 2023 Jiaxing Xu, Aihu Zhang, Qingtian Bian, Vijay Prakash Dwivedi, Yiping Ke

We first investigate different kinds of connectivities existing in a local neighborhood and identify a substructure called union subgraph, which is able to capture the complete picture of the 1-hop neighborhood of an edge.

IMF: Interactive Multimodal Fusion Model for Link Prediction

1 code implementation20 Mar 2023 Xinhang Li, Xiangyu Zhao, Jiaxing Xu, Yong Zhang, Chunxiao Xing

To this end, we propose a two-stage multimodal fusion framework to preserve modality-specific knowledge as well as take advantage of the complementarity between different modalities.
