Privacy Preserving Disease Prediction Across Multiple Hospitals Using CKKS Based Homomorphic Federated Learning

This paper proposes a CKKS-based homomorphic federated learning framework that enables privacy-preserving disease prediction across multiple hospitals by encrypting model updates to prevent membership inference attacks, though this enhanced security comes at the cost of significant communication overhead and reduced predictive utility compared to plaintext approaches.

A label-free geometric diagnostic tracks when removing a domain subspace helps out-of-distribution seed classification

This paper proposes and validates a label-free geometric diagnostic that uses the angle between domain subspaces and class-discriminative directions to predict when removing domain-specific information will improve out-of-distribution seed classification, particularly under severe deployment shifts where traditional selection methods fail.

ACO-QSNR: An Ant Colony Optimization and Q-Learning-Based SNR-Aware Cross-Layer Routing Protocol for Mobile Ad Hoc Networks

This paper proposes ACO-QSNR, a novel cross-layer routing protocol for Mobile Ad Hoc Networks that integrates Ant Colony Optimization and Q-learning with SNR-aware metrics to outperform conventional protocols like AODV in terms of packet delivery ratio, throughput, and delay under dynamic mobility and varying node densities.
