CQSA: Byzantine-robust Clustered Quantum Secure Aggregation in Federated Learning

arXiv:2602.22269v1 Announce Type: new Abstract: Federated Learning (FL) enables collaborative model training without sharing raw data. However, shared local model updates remain vulnerable to inference and poisoning attacks. Secure aggregation schemes have been proposed to mitigate these attacks. In this…

Global graph features unveiled by unsupervised geometric deep learning

arXiv:2503.05560v3 Announce Type: replace Abstract: Graphs provide a powerful framework for modeling complex systems, but their structural variability poses significant challenges for analysis and classification. To address these challenges, we introduce GAUDI (Graph Autoencoder Uncovering Descriptive Information), a novel unsupervised…

Prior Knowledge-enhanced Spatio-temporal Epidemic Forecasting

arXiv:2602.22270v1 Announce Type: new Abstract: Spatio-temporal epidemic forecasting is critical for public health management, yet existing methods often struggle with insensitivity to weak epidemic signals, over-simplified spatial relations, and unstable parameter estimation. To address these challenges, we propose the Spatio-Temporal…

Support Tokens, Stability Margins, and a New Foundation for Robust LLMs

arXiv:2602.22271v1 Announce Type: new Abstract: Self-attention is usually described as a flexible, content-adaptive way to mix a token with information from its past. We re-interpret causal self-attention transformers, the backbone of modern foundation models, within a probabilistic framework, much like…

Agentic Framework for Epidemiological Modeling

arXiv:2602.00299v2 Announce Type: replace Abstract: Epidemic modeling is essential for public health planning, yet traditional approaches rely on fixed model classes that require manual redesign as pathogens, policies, and scenario assumptions evolve. We introduce EPIAGENT, an agentic framework that automatically…

Positional-aware Spatio-Temporal Network for Large-Scale Traffic Prediction

arXiv:2602.22274v1 Announce Type: new Abstract: Traffic flow forecasting has emerged as an indispensable mission for daily life, which is required to utilize the spatiotemporal relationship between each location within a time period under a graph structure to predict future flow.…
