Distributionally Robust Graph-based Recommendation System

1 code implementation20 Feb 2024 Bohao Wang, Jiawei Chen, Changdong Li, Sheng Zhou, Qihao Shi, Yang Gao, Yan Feng, Chun Chen, Can Wang

DR-GNN addresses two core challenges: 1) To enable DRO to cater to graph data intertwined with GNN, we reinterpret GNN as a graph smoothing regularizer, thereby facilitating the nuanced application of DRO; 2) Given the typically sparse nature of recommendation data, which might impede robust optimization, we introduce slight perturbations in the training distribution to expand its support.

MS-Former: Memory-Supported Transformer for Weakly Supervised Change Detection with Patch-Level Annotations

1 code implementation16 Nov 2023 Zhenglai Li, Chang Tang, Xinwang Liu, Changdong Li, Xianju Li, Wei zhang

How to capture the semantic variations associated with the changed and unchanged regions from the patch-level annotations to obtain promising change results is the critical challenge for the weakly supervised change detection task.
