Leveraging Peer-Informed Label Consistency for Robust Graph Neural Networks with Noisy Labels

IJCAI 2025

Graph Neural Networks (GNNs) excel in many applications but struggle when trained with noisy labels, especially as noise can propagate through the graph structure. Despite recent progress in developing robust GNNs, few methods exploit the intrinsic properties of graph data to filter out noise. In th

Variational Perturbation Personalized Federated Learning via Prior-Posterior Distance

ICASSP 2025accepted

Personalized Federated Learning (pFL) mitigates the impact of statistical heterogeneity on FL architecture to some extent by allowing participants to use personalized models based on local data distributions. The existing pFL methods optimize from the perspective of model structure, attempting to ad…

PGTRNET: Two-Phase Weakly Supervised Object Detection with Pseudo Ground Truth Refinement

ICASSP 2022accepted

Current state-of-the-art weakly supervised object detection (WSOD) studies mainly follow a two-stage training strategy which integrates a fully supervised detector (FSD) with a pure WSOD model. There are two main problems hindering the performance of the two-phase WSOD approaches, i.e., insufficient…
