Structural Alignment based Zero-shot Classification for Remote Sensing Scenes

2018

Zero-shot classification aims to classify unseen classes instances without any training data. However, the problem of class structure in consistency between visual space and semantic space severely affects zero-shot classification performance for remote sensing scenes. …

An Adaptive Differential Privacy Method Based on Federated Learning

2024 · arXiv (Cornell University)

Differential privacy is one of the methods to solve the problem of privacy protection in federated learning. Setting the same privacy budget for each round will result in reduced accuracy in training. The existing methods …

Graph Segmentation and Contrastive Enhanced Explainer for Graph Neural Networks

2025 · Proceedings of the AAAI Conference on Artificial Intelligence

Graph Neural Networks are powerful tools for modeling graph-structured data but their interpretability remains a significant challenge. Existing model-agnostic GNN explainers aim to identify critical subgraphs or node features relevant to task predictions but often …
