Analog Over-the-Air Federated Learning With Real-World Data

2022

Federated edge learning enables intelligence services to be deployed at the edge of future wireless network. To address the limited spectral resource and constrained scalability, analog over-the-air federated learning is recently proposed to achieve fast …

SPA: A poisoning attack framework for graph neural networks through searching and pairing

2025 · Machine Learning

Graph Neural Networks (GNN) have played an important role in many fields, while GNNs also suffer from adversarial attacks that aim to malfunction the GNN model by changing the adjacency matrix (i.e. generating adversarial edges) …
