NTA-Gossip: Learning When Not to Learn in Decentralised Federated Learning

Mamba–LSTM for Long-Horizon Shoreline Prediction Using Satellite Imagery

Coastal erosion forecasting is central to climate adaptation and risk management. However, shoreline dynamics exhibit complex spatio-temporal patterns with both local variations and long-range dependencies that conventional recurrent models struggle to capture efficiently. We propose a hybrid Mamba-LSTM framework for m...

SAGE: Optimal-Stopping Peer Selection for Decentralised Federated Learning

This work proposes SAGE (Sequential Anchor-Gated Exchange), an optimal-stopping peer selector under a one-model-bearing-exchange budget, and shows that the selector never returns a peer worse than random gossip with high probability, and proves that no such guarantee holds for selectors that commit without a certificat...
